How to replace your SIM Card with a Micro SIM or Nano SIM Card

September 22nd, 2015

If you’re changing smartphone, you may also need to change the size of your SIM card. Newer devices typically require a Micro SIM or Nano SIM.

If you’ve recently got your hands on a new smartphone, there’s a good chance it’ll require a Micro SIM or Nano SIM. Before you’re able to use your SIM card in the new handset, you’ll need to first make sure it’s of the right size. In some cases, it will be necessary to replace your current SIM card with a Micro SIM or Nano SIM.

In this article, we’ll explain how to change your current SIM card for a Micro SIM or Nano SIM. We’ll discuss the process on each UK network and how much you can expect it to cost. We’ll also discuss the option of manually cutting your SIM card down to size.

Which size of SIM Card is required for my phone?

SIM Card SizesAs of 2015, there are now three types of SIM card currently in use: Standard SIM, Micro SIM and Nano SIM.

The oldest handsets typically use a standard-size SIM card (measuring 25mm x 15mm). For newer handsets released in the last couple of years, it’s more likely you’ll need a Micro SIM or Nano SIM. Micro SIMs measure 15mm x 12mm whereas Nano SIMs measure 12.3mm x 8.8mm.

If your current SIM card is of the wrong size for your handset, you’ll need to replace it for a SIM card of the right size.

The following table shows the required size of SIM card for some commonly-used handsets today:

Standard SIM

  • Apple: iPhone 3GS and older
  • BlackBerry: Bold, Curve
  • Samsung: Galaxy S II and older, Galaxy Note (original)

Micro SIM

  • Apple: iPhone 4 & iPhone 4S
  • HTC: One M7, One S, One X
  • LG: G4, G3, G2, Nexus 5, Nexus 4
  • Microsoft: Lumia 540, Lumia 640
  • Motorola: Moto G, Moto E
  • Samsung: Galaxy S5 and older, Galaxy Note 4 and older
  • Sony: Xperia Z2 and older, Xperia M2, Xperia E3

Nano SIM

  • Apple: iPhone 5 and newer
  • BlackBerry: Passport
  • HTC: One M8 and newer
  • Motorola: Moto X, Nexus 6
  • Nokia: Lumia 735, Lumia 930, Lumia 1520
  • Samsung: Galaxy Alpha, Galaxy S6 and newer
  • Sony: Xperia Z3 and newer

To find out exactly which size of SIM card is required by your smartphone, please select your handset from the following options:

For more information, please see our full guide to the different types of SIM card. This will explain in more detail the differences between Standard SIM, Micro SIM and Nano SIM.

Changing to Micro SIM or Nano SIM

iPhone 6 Plus and Samsung Galaxy S6 Edge

Newer smartphones typically use either a Micro SIM or Nano SIM.

If you’re purchasing an upgrade directly from your mobile network, they’ll normally send you a replacement SIM card along with the new phone. The new SIM card should be of the right size to fit in your new handset. If you didn’t receive a replacement SIM card, contact your mobile network and ask for a replacement. Please note that upon activating your new Micro SIM or Nano SIM, your old SIM card will cease to function. Before switching over, be sure to copy your text messages and phone numbers.

If you purchased your handset SIM-free or on a Pay As You Go basis (or if you received the handset as a gift from someone else), you’ll need to manually exchange your current SIM card for a new SIM of the right size. There are three ways you’re able to do this:

1. Out of Contract? Get a “Micro SIM Only” or “Nano SIM Only” Deal.

If you’re no longer tied in to the minimum term of your contract (i.e. if you’re more than 24 months into your Pay Monthly contract), the best thing to do is to switch over to a “Micro SIM Only” or “Nano SIM Only” deal. You’ll get a new tariff which typically saves you £20/month (about £240 over the next 12 months). You’ll also get a new SIM card for free which will be of the right size to fit in your new smartphone.

As a quick sample of some of the deals currently available:

* The BT Mobile tariffs have a £5/month discount for BT Broadband customers. BT also has a SIM card for only £5/month with 200 minutes, unlimited texts and 500MB of 4G data.

To order a “Micro SIM Only” or “Nano SIM Only” tariff, choose your mobile network followed by the size of SIM card you require:

2. During Your Contract: Ask your mobile network to replace your SIM card.

If you’re currently in the middle of a contract, you can ask your mobile network to replace your existing SIM card. If you do this, you can stay on the same contract and price plan as before. Everything remains the same including the price you pay: the only difference is you’re able to use a Micro SIM or Nano SIM.

EE

EE, Orange & T-Mobile

For customers on EE and T-Mobile, it’s £10.20 to get a replacement Micro SIM or Nano SIM. For Pay Monthly customers, this is charged to your next monthly bill. For Pay As You Go customers, the money will be taken from your airtime balance. For customers on Orange, replacement SIM cards are available for free.

The fastest way to get a replacement Micro SIM or Nano SIM is by visiting your nearest EE retail store. Here, the SIM card swap-over will take less than hour. If you aren’t able to easily visit an EE store, you can also order a replacement SIM card online (it may take a couple of days for the SIM card to arrive). Upon getting your new SIM card, you can activate it here on the EE website. For more information, please refer to the EE help page.

giffgaff

giffgaff

giffgaff doesn’t charge for a replacement Micro SIM or Nano SIM. You can order a replacement SIM card from the giffgaff website. It can take up to 7 working days for the SIM card to arrive. When the new SIM card arrives, use the online SIM swap tool to get your SIM card changed over. It normally takes about 30 minutes for the SIM Swap to finish.

O2

O2

O2 will replace your SIM card free of charge in their nearest retail store. This is the quickest way to get a replacement Micro SIM or Nano SIM. If you aren’t able to visit a store in person, you could alternatively call O2 Customer Services to have a SIM card sent out (dial 202 if you’re a Pay Monthly customer or 4445 if you’re on Pay As You Go). If a SIM card is being sent to you through the post, use the online SIM swap tool to get your number moved over.

Tesco Mobile

Tesco Mobile

Tesco Mobile can send you a replacement SIM card free of charge. To do this, you’ll need to call Tesco Mobile Customer Services on 4455. They’ll send you a replacement Micro SIM or Nano SIM within 3 working days. Once the new SIM card arrives through the post, follow the instructions here to get the new SIM card activated.

Three

Three

Three is able to replace your existing SIM card with a new Micro SIM or Nano SIM. You can do this in a nearby Three retail store. Normally, it costs £5 to get a replacement SIM card from Three. However, inform the staff that you’re changing the size of your SIM card and they shouldn’t charge you anything for the replacement.

Virgin Mobile

Virgin Mobile

Virgin Mobile can send you a replacement Micro SIM or Nano SIM free of charge through the post. A replacement SIM card will normally cost you £5 but it should be free if you tell them you’re changing the size of your SIM card. You can request a replacement SIM card by calling Virgin Mobile Customer Services on 789. It’s not currently possible to get a replacement SIM card in store.

Vodafone

Vodafone

Vodafone can replace your SIM card with a new Micro SIM or Nano SIM totally free of charge. It can take up to 15 minutes to do this at your nearest Vodafone retail store. Alternatively, you can contact Vodafone Customer Services on 191 and they’ll send you a SIM card through the post.

3. Alternative: Cut your SIM card down to size.

If you’re switching from Standard SIM to Micro SIM, the only difference between the two SIM card types is the amount of plastic that surrounds the metallic chip. For this reason, it’s possible to cut down the SIM card yourself into Micro SIM dimensions. The easiest way to do this is by purchasing a specialist Micro SIM Cutter. These are available from Amazon for around £5.

Users who are slightly more daring can follow these DIY instructions to cut their own Micro SIM with a ruler and a pair of scissors. Please note that cutting your own Micro SIM could damage it if performed incorrectly. A broken or badly-cut Micro SIM could possibly cause damage to your phone. If at all possible, we recommend ordering a replacement SIM card directly from your mobile network. Except from on EE and T-Mobile, it’s free to obtain a replacement SIM card from your network.

If you’re switching to a nano-sized SIM card, please be aware that it’s not possible to cut a regulation Nano SIM. This is because Nano SIMs are slightly thinner than Standard and Micro SIMs. Although you’re able to cut your SIM card length-wise and width-wise, the trimmed-down Nano SIM will be a little too thick. We don’t recommend cutting your own Nano SIM as an oversized SIM card could cause damage to your handset.

SIM Type Length (mm) Width (mm) Height (mm)
Standard SIM 25.00 15.00 0.76
Micro SIM 15.00 12.00 0.76
Nano SIM 12.30 8.80 0.67

The dimensions of a standard SIM card, micro SIM card and nano SIM card. For more information, see our comparison of the different SIM card types.

Using a Micro SIM or Nano SIM in Older Handsets

After changing the size of your SIM card, it should normally still be possible to use the SIM card in older handsets. If you own a handset that requires a standard-size SIM card, a SIM card adapter will make it possible to use a Micro SIM or Nano SIM. Adapters can readily be purchased online for less than £5. Nano-to-Micro SIM adapters are also available for about the same price.

Once you’ve received an adapter, do take additional care. You shouldn’t place the adapter in a smartphone unless a SIM card is first placed in the adapter. An inserted adapter without a SIM card inside may cause damage to your handset when it is finally removed.

Finally, you should also be warned that certain handsets are incompatible with adapters. Incompatible handsets include the Nokia N8, BlackBerry Bold 9700, Sony Ericsson X10 and the Samsung Galaxy Note. These devices contain a push-in SIM card slot with delicate and flexible metal pins that connect to the SIM card. Using an adapter in one of these devices can cause permanent damage to the SIM card slot. The All About Symbian website has a great report on the different types of SIM card slots and the possible damage from adapters.

Order a Replacement Micro SIM or Nano SIM

There are two ways to get a replacement Micro SIM or Nano SIM.

The first way is to get a “Micro SIM Only” or “Nano SIM Only” contract: you can do this online via your mobile network’s website. It’ll save you money on your line rental every month and you’ll get a suitably-sized SIM card for no extra charge. Refer to the website of your mobile network operator for more information: BT Mobile, EE, giffgaff, O2, Tesco, Three, Virgin Mobile and Vodafone.

The second way of getting a replacement SIM card doesn’t involve changing your contract or tariff. You’ll either need to contact customer services or you’ll need to visit your mobile network’s local retail store. More information can be found here.

      Ken replied:

      Hi Gill,
      Thanks for your comment. Yes, your mobile network will transfer your entire account over to the new SIM card including any Pay As You Go credit you may currently have on it 🙂

    Hi ken I’ve a very old sagem non_smartphone with std Sim. Pay as you go. Thinking of buying a Samsung that takes micro Sim. If I ask network provider of existing phone for new Sim, will it have same telephone number as I don’t want a new number, and will it contain the contacts etc that are on existing std sim? Or will I need to reload everything?

      Ken replied:

      Hi Tony,
      Thanks for your comment. Yes – your mobile network can provide you with a new micro-SIM on the same phone number to replace your old SIM card. Your phone book won’t transfer over to your new phone, however, so you’ll need to move these over yourself.
      Hope this helps,

    For the past fortnight Vodafone have not been able to swap sims from a Moto G to an iPhone 5s. Every time it fails, so far 6 times, and the Vodafone shop is having no luck either. I am now on my fifth nano sim. No one seems able to explain why and I feel the problem lies elsewhere. Any ideas? The helpline just expresses disbelief and sends another sim! Do you think this will ever be resolved?

    Hi Ken,

    My 75 year old mum had a Nokia 2700 Classic standard mobile phone. It died the other day and she took it into town today to see if it could be repaired. The guy said the battery was fine, did a few other checks and couldn’t find the problem.

    She came home with a Samsung Keystone 2, using her own sim card. Unfortunately, along with having no camera on the phone – which the guy didn’t tell her, the only data showing is two telephone numbers. I suspect it’s the last two contacts on her sim card because it’s contacts beginning with S and T.

    There are no signs of her media files which were videos and photographs – lots of my nephew when he was a baby – and no saved text messages, either. As there’s no camera on the newer mobile I suspect there’d be nowhere to store the media files anyway.

    Is there any way to retrieve the media files from the sim card?

    Thanks in advance for any help and/or advice.

    Kind regards.

    Pauline

      Hi Pauline,
      Thanks for your comment. Unfortunately, your mum’s media files were probably saved on the Nokia 2700 – the same goes for the text messages and phone book (there is a way to copy your phone book to a SIM card but this requires you to do it on the original handset). Unfortunately, the SIM card does not store any of this information. Is it possible to somehow retrieve her old handset?
      Sorry I couldn’t be more helpful with this,

        Hi Ken,

        Thank you so much for your reply and the information you provided.

        A bit of an update regarding this subject if I may.

        Not happy at all with the Samsung handset, I managed to get my mum the exact same Nokia 2700 Classic mobile from eBay. Same colour, too, she was over the moon.

        However, although the phone arrived boxed and unopened, when we took the back cover off the phone to put the SIM card in, we couldn’t get the battery to sit in place ‘flush’ – and we couldn’t get the back cover on the phone. We assumed we couldn’t get the cover on because the battery wasn’t sitting flush in the handset.

        Mum still has the original handset. So, I took the battery out of the original handset, put it into the newer one and tried to put the new cover on. The cover wouldn’t go on. It sits in place along the right of the phone but not the left; the left is where the battery is ‘sticking out’ a bit in the newer handset, so maybe it’s warped due to the pressure of the battery sticking out? I don’t know. I took the old cover from the original phone and it went on the newer handset without any problem but only with the old battery inside. I hope this isn’t too confusing; believe me, it was for us and we were there!

        I paid £20.99 including P&P for the replacement handset. I’ve told my mum that if she’s happy with using the older battery and cover then it’s her decision if she wants to keep it rather than me contact the seller on eBay, and she has to wait until I return the handset before he sends out another one.

        So, yes, we still have the original handset, Ken, which is just as well 🙂

        Kind regards,

        Pauline

          Hi Pauline,
          Does the new device have a swollen battery? If so, it’s definitely important to be careful with it: this might be caused by a manufacturing defect or improper use in the past. As you say, you can use the old battery in the mean time or you can possibly get a replacement device from the seller on eBay.

    Hi want to buy a new phone but my sim card is too big for new one. My contract is over but my package is all you can eat data which I want to keep. Would it be possible to ask 3 for a new one and still keep the package i’m on?? Thanks In advance Lynn

    1. Ken Lo
      Ken replied:

      Hi Lynn,
      Thanks for your comment. Yes – of course! Just go in to a Three retail store and ask them for a replacement. They’ll transfer your existing phone number and plan to a smaller-size SIM card (no need to change to a new plan).

    How can I implement the ‘Sim Card Finder’ on my website, hiloplace.com, for US carriers, such as Verizon, AT&T , Sprint. Metro PCS and Cricket?

    We sell Verizon sim cards and get asked this question at least 25 times per week.

      Hi there,

If you want an easy way for your customers to find out which size of SIM card they require, you could consider linking them to http://kenstechtips.com/index.php/smartphone-type-standard-sim-micro-sim-or-nano-sim. There’s a table on the page showing the size of SIM card required for each handset.

    Hi. I have an iPhone 5c that has stopped working properly. I still have a few months on my contract before I can get an upgrade. However, I wanted to move the sim from this iPhone to an older iPhone I have that worked very well before I upgraded. However, the newer model has a very small sim which is too small to fit into my older iPhone. What can I do?

    1. Ken Lo
      Ken replied:

      Hi Tess,
      The chances are your old iPhone is using micro-SIM rather than nano-SIM (you can double-check the table on this page). You can either ask your mobile network for a replacement micro-SIM or alternatively, you can use your existing nano-SIM through a SIM card adapter.
      Hope this helps,

    Hi Ken,

    What a great page full of useful information which I have read through with interest along with a lot of the comments. I do still have a question though namely……..

    You say higher up in your article……….
    “Please note that upon activating your new Micro SIM or Nano SIM, your old SIM card will cease to function.”

    I have just come off a 24 month contract with EE and moved over to a 12 month SIM only deal with them without any issues. My existing handset is an HTC One Mini with a Micro SIM but I bought a Samsung Galaxy S6 off e-Bay tonight which I see will need to have a Nano. In an ideal world I would like EE to send me the Nano as a duplicate rather than “replacement” SIM so that I can leave my HTC One alone and have it still available to me on my existing number as a backup handset. Is there even a remote possibility of this? Why does it have to be a case of either/or particularly when we as end users of the phone companies products and services are not the ones who changed the SIM sizes.

    1. Ken Lo
      Ken replied:

      Hi Sare,
      Thanks for your comment. Unfortunately, due to technical limitations, phone numbers can only be associated with one SIM card at a time. This is the reason why you wouldn’t be able to have both a Micro SIM and Nano SIM active at the same time. You could continue to use your HTC One Mini but this would probably require you to use a Nano-to-Micro-SIM adapter (N.B: I recommend a lot of caution with adapters as described above in this article). Alternatively, you could use a different SIM card in the HTC One Mini and you could then set up call forwarding from the Galaxy S6 when appropriate (of course, this would require you to pay for two separate contracts).
      This problem of different SIM card sizes is a really common frustration I experience myself, especially when testing out different handsets requiring different sizes of SIM card!

    Hi Ken wondered if you could help! I have been given a blackberry bold 9790 but I have a nano SIM card so I want to use a SIM card adapter, I’ve read a lot of articles about people breaking their blackberrys by using SIM card adapters that are too thick. Can you recommend an adapter that fits? I also imagine it’s now hard to get a replacement SIM card that’s mini ?

    1. Ken Lo
      Ken replied:

      Hi Rachael,
      Thanks for your comment. I’d recommend against using a SIM card adapter whenever possible – if you do so, it’s obviously at your own risk (sorry I don’t have any adapters I’m able to recommend). It is still possible to get a replacement mini-SIM: you can order one through the links on this page.
      Hope this helps,

    Hi Ken

    I’m in a world of pain with all this. I have a Galaxy 2 it’s time to change up. So, at my friends recommendation, I bought a Vodaphone ultra 6. I was told I could swap sim card and unlock it.

    However, I tried to activate and unlock the new phone but the sim won’t fit (micro won’t fit into nano). What can I do? The whole reason for buying the vodaphone ultra 6 was because I was told it would be really simple to transfer all my stuff across.

    But if the sim doesn’t fit I can’t even begin to use the new phone. Let alone move my stuff across.

    As you can probably tell, I am vey new and uncomfortable with all this. The amount of codes and back up this and that is utterly baffling for me.

    What would you recommend I do to get the new phone running with as much stuff off the old one as possible.

    As far as I can tell the old phone doesnt have an sd card.

    Is there such a thing as a service that just does all thid for you?

    Or have I just thrown £115 down the toilet?

    May thanks

      Hi Clive,
      Thanks for your comment. As a Vodafone customer, you should be able to walk in to any of their stores and ask them for their ‘Red Box’ service. This will connect up to both of your phones and it should copy the data over for you automatically.
      Hope this helps,

    Hi Ken,
    I’ve an Iphone 4s but my brother has given me his unlocked Iphone 5. I’m on three network and won’t be changing my number or contract. I realise I’m going to need a nano sim. When I change over to the new nano sim, will all my data, like contact numbers, messages, photos and whatsapp automatically transfer to the nano sim? Also, I’ve never backed up my 4s as not sure what to do. My Icloud is full too. Would really appreciate your guidance. Thanks

      Ken replied:

      Hi Barbara,
      Thanks for your comment. Unfortunately, data like phone book, messages and photos will not transfer to your new iPhone automatically. Rather, you’ll need to follow the instructions here (transferring your data either through iCloud or iTunes). For WhatsApp, you should also make a backup of your messages to an iCloud account. You can do this by going to WhatsApp Settings > Chats > Chat Backup.
      Hope this helps,

    Hi My daughter has a motorola with a micro sim. The phone is playing up but we are still in contract on pay monthly with tesco. I am buying an i phone off a friend 5S and it needs a nano sim. what is best cut the sim or ask tesco for a nano sim and keep the contract going. If they send i new sim is it possible for her to keep her number. Thanks Denise

    1. Ken Lo
      Ken replied:

      Hi Denise,
      Thanks for your comment. With nano-SIM, I’d strongly recommend asking Tesco to give you a replacement. You can do this by calling 4455 from your Tesco Mobile handset (it’s free of charge to get a replacement nano-SIM). Your new SIM card will maintain the same phone number as before.
      Hope this helps,

    1. Ken Lo
      Ken replied:

      Hi Faye,
      Thanks for your comment. Are you keeping the same Pay As You Go account as before? If so, you’ll need to change her current SIM card for a micro-sized SIM (instructions can be found in the article above). If she’s also changing network or account at the same time, take a look at my guide to using a PAC Code.
      Hope this helps,

    Big Ken what’s up,
    I’ve had a really cheap £10 Nokia phone with an old sim card for ages now, but I’ve finally got a hand- me-down Samsung galaxy S4 mini which requires a micro sim. Is it possible to buy a new micro sim from Tesco mobile and swap my old number (also Tesco) from the old sim to the new micro sim?
    Otherwise I might try the ‘cutting down’ technique – but will the ancient sim work in a newish smartphone?

    Thanks for your time!

      Hi Olly,
      Thanks for your comment. If you want to keep your current plan, Tesco Mobile can send you a replacement SIM card free of charge through the post (to get one, you should call Tesco customer services on 4455). If you’d like to take out a new plan, you can also order a new SIM card from their website.

    Hello, I have purchased a Samsung s6 edge for my son as a Christmas gift and now realise I have to get a nano SIM card for it. He is currently on 3 network. So
    1. Do I just call into my local store and ask for a nano SIM card
    And
    2. How do I transfer contacts etc from his micro to nano sim?

    He is on a £7.50 per month rolling contract also at the moment.

      Ken replied:

      Hi Rob,
      Thanks for your comment. To answer your two questions in order:
      1. Is he already using the Galaxy S6 Edge or is the gift due to be opened on Christmas Day? If he’s already using the Galaxy S6 Edge, the fastest thing to do is to go to a Three retail store (they’ll give you a replacement nano-SIM on the spot at no charge). If the gift is going to be opened at Christmas, you can either go to the Three retail store on Boxing Day to change your SIM card over or you can order a nano-SIM in advance by calling 333 (with the latter option, you can get the nano-SIM in advance – you would then activate the SIM card on Christmas Day).
      2. Nowadays, it’s very rare for the phone numbers to actually be stored on the SIM card. Which phone is he transferring over from? My recommendation is to make sure the contacts are synced with Google (that way, they’ll appear automatically on the new phone owhen he signs in).

    Hi Ken, very useful page. My son is going from an ancient standard SIM to a micro SIM. I used to be able to get a T-Mobile SIM from any shop, even if they now have an EE logo and you need to look a little harder for the pink T-Mobile logo as well. Some EE stores used to run out but now it seems no one has them! I ordered one free from EE as I am a contract customer with them. It should arrive tomorrow then we can have fun seeing if we can retain T-Mobile boosters!
    My wife is going from micro SIM to nano SIM still on T-Mobile so hopefully that can be ordered on the phone at no extra cost.
    EE are trying their best not to promote T-Mobile any longer!

    Dear Ken, I’ve just recently purchased a new BLU – WIN JR LTE 4G Dule sim smartphone, but like most phones the instructions are not always understandable. I suffer from dyslexia so following instructions sometimes poses a problem. What I am trying to find is the type of sim card, this phone requires, I am currently on Tesco pay as you go, Which is the standard sim, can I cut this card down or would it be simpler to order two new cards. And if I order new cards can I keep my existing phone number as I’ve had the same number for 10 years now and would not wish to change. Can you please help me.

    1. Ken Lo
      Ken replied:

      Hi Gordon,
      Thanks for your comment. I’ve had a quick look on Google and it looks as if the Blu Win JR LTE uses micro-sized SIM cards. You can get a replacement micro-SIM from Tesco Mobile by giving them a call on 4455 (it will typically take about 3 working days to arrive in the post). You’ll then need to follow the instructions here to activate the new micro-SIM.
      Hope this helps,

    Hi Ken

    Thanks for a really useful column. I’ve just bought a Sony Xperia Z3 which (I have now discovered) needs a nano sim card (this was not immediately made apparent). I currently have a Samsung S4 mini, with a standard sim card. I’m with EE. I understand that EE should be prepared to send me a replacement nano sim card, but Ii’m not at all clear how I can transfer my data (phone nos., e-mail addresses, etc etc) between a)one size sim card and another and b) one brand smartphone and another. I’ve got all my contact data on the current sim card, but am not sure what to do with it next to get it to the Sony. The Experia transfer software doesn’t seem to recognise my Samsung. Any hints gratefully received

    Thanks

      Ken replied:

      Hi Danny,
      I recommend syncing the phone book from your Galaxy S4 Mini to your Google Account. This way, your phone book will be stored in the cloud and will appear automatically on your new device. You can do this by opening the Contacts application, tapping Menu and then ‘Merge with Google’ (the exact naming of the option might vary depending on your handset).
      The other thing you could also try is using Samsung’s Kies desktop software. This will copy your contacts on to a computer: you can then copy them from there onto your Xperia Z3.
      Hope this helps,
      Ken

      1. Danny Friedman replied:

        Many thanks Ken – only problem was that somehow it also managed to grab hundreds of e-mail addresses from my PC and stick them in my Contacts on the new phone, so I’ve had a merry day or two weeding them out. But got there in the end!

      Hi Jane,
      Thanks for your comment. You can get a replacement Micro SIM from Virgin by calling Customer Services on 789 (0345 600 0789 from a non-Virgin handset). I believe they currently charge £2.99 for first class postage and £7.99 for next-day delivery.

    1. Ken Lo

      Hi Tony,
      I believe the Xperia T3 uses micro-sized SIM cards though it’s possible I could be mistaken. Have you tried comparing the SIM card slot dimensions to the SIM card sizes in the table above? This should help you confirm which size of SIM card is actually required.
      Many thanks,

          Ken replied:

          Hi Tony,
          Thanks for your comment. Unfortunately, without seeing your actual SIM card, it’s difficult to say how much plastic you need to remove! The best thing to do is to compare your SIM card against the following diagram:
          SIM Card Sizes: Standard, Micro and Nano SIM
          Micro SIM is the one in the middle. You’ll need to pop out the SIM card so it matches this one (the Micro SIM dimensions will be 15mm x 12mm). Do be careful as some networks now provide a Trio SIM (the Nano SIM will pop out from the centre of the Micro SIM).
          Ken

          1. Tony replied:

            Thanks very much Ken. The problem has been resolved. The difficulty arose because the instructions which came with the phone and the “how to” video’s did not point out that there was a ,micro sim sized plastic insert which needed to be removed before the sim card could be inserted. Hope I did not waste your time!

      Hi Tracey,
      Thanks for your comment. Your husband’s mobile network will be able to change his micro-sized SIM card for a nano-sized SIM. It’s normally free to do this on most networks (£10.21 if he’s a customer of EE or T-Mobile). He should contact his mobile network to request a replacement SIM (more information in the article above). The new SIM card will have the same phone number and will also have all of the Pay As You Go credit.

      Thanks for your comment and sorry to hear about the loss of the iPhone.

A replacement SIM card is normally free of charge (though it costs £10.21 on T-Mobile and EE). If your iPhone 4s was previously used on a different network, it may also be necessary to first unlock the iPhone.

If the first, you can simply ask Three to replace your Micro SIM with a nano-sized SIM card. It’s free to do this in any Three retail store. If the latter, you should contact Three customer services as per the information on this page. They should be able to move your phone number over.

    Dear ken
    I have unlocked (bought from ebay) a samsung galaxy s4 zoom with solid camera.

    It says only micro sim card works in it. For a trial I bought, in 99p shop, a micro sim. Vodafone have been placed but says no sim.

    1. Does the Vodafone SIM card work only after topping up??
    2. Or shall I try another company?? Since Samsung says certain companies have certain rules to operate their system??
    3. Or the phone itself is locked?? But in ebay only new unlocked phones are sold??
    4. With vodafone no way to have answer?? Tried many times.

    Please help will appreciate with sold response.

    I do not necessarily need vodafone – any sim card I am willing to use just to check the phone is ok. But please suggest, will buy as many as i can see.

    Thanks

    1. Ken Lo
      Ken replied:

      Hi Peter,
      Thanks for your comment. To answer your questions in order:
      1. Normally, the SIM card should work immediately. It will show coverage on your phone even if you’re unable to make calls due to no credit. I suspect the Vodafone SIM card is probably dodgy (you can try returning it and getting a replacement or you can try using the SIM card in another smartphone). I recently bought a SIM card from another company and experienced the same problem due to a malfunctioning SIM.
      2. It’s well worth trying a SIM card from a different company. See the article here for a full list of free Pay As You Go SIM card offers in the UK. If it still doesn’t work with SIM cards from another company, it may be a problem with the handset instead.
      3. If your phone was locked, it would show a different message when you insert the SIM card from Vodafone.
      4. The best way to get support from Vodafone is probably to go into one of their retail stores (the staff there will be able to examine your handset & SIM card directly). Saying that, if it’s a problem with a malfunctioning SIM and if you aren’t too bothered about which network you want, it’s probably easier just to order another Pay As You Go SIM card.
      Hope this helps,
      Ken

      Hi Mike,
      Thanks for the feedback. I haven’t heard anything about EE no longer providing replacement SIM cards in store. Are you sure this is definitely the case? I’d be very surprised if they stopped doing this as many people require a SIM card quickly (e.g. if you lose your phone). My suggestion is to go back and try again either in a different store or with a different member of staff. Alternatively, you can order your replacement SIM card online but you’ll need to wait around 2 working days.

If so, you can ask Tesco to replace your Micro SIM with a nano-sized SIM card (the phone number will be moved automatically onto the new nano SIM). If you’re trying to move the contacts/phone numbers saved on your phone, HTC has created a handy tool (HTC Sync Manager) which should do pretty much what you’re looking for!

      Ken replied:

      Hi Anthony,
      Thanks for your comment. Unfortunately, as far as I’m aware, no UK network allows you to have two SIM cards with the same phone number. The only way you’d be able to have both your smartphone & smartwatch ringing at the same time is by using Bluetooth instead of separate SIM cards. If you’d like to have both devices using the same plan, EE does offer a choice of shared plans but each SIM card will have its own number.

          Okay, third time lucky. I received the nano sim on Friday 20 March. Maybe phoning them did the trick! The sim was for a Galaxy Alpha.
          So I contacted them to activate it on the Friday afternoon. it would take 24 hours to do this they said. 24 hours later I phoned them to say it still isn’t working, sorry they said we will try to do it now. Eventually half an hour later it was working. All I can say is persistence works sometimes.
          I had cut my old sim card down to fit in the Alpha and it worked okay but I thought I would get the proper card for it. Maybe I should have listened to the old adage, don’t try to fit something that’s not broken.

      Ken replied:

      Hi Victor,
      Thanks for your comment. Unfortunately, it’s difficult to diagnose the exact reasons why your SIM card is no longer working. It could be a multitude of reasons (e.g. a badly cut nano-SIM which is no longer aligned properly, the chip within the SIM card being damaged or the iPhone 5c being locked to another network). Based on what you’ve said about the SIM card no longer working in a BlackBerry Q5 (presumably this is using an adapter to enlarge it to micro-SIM?), my guess is it’ll be one of the first two. Would it be possible for you to visit a local store and to pick up a replacement nano-SIM? This should hopefully solve the problems you’re having.

      Hi Steven,
      Take a look at my article on unlocking an iPhone – it should hopefully answer all of your questions. To answer your question briefly, the best thing to do would be to ask your friend to request the unlock from Tesco. It’ll cost them £20 unless they happen to have paid off the ‘Phone payment’ part of their plan. If your friend isn’t able to request the unlock, you could probably do itself using a Tesco Mobile Pay As You Go SIM card. Once again, it’ll cost you £20 but you’ll need to activate your SIM card first.

      Thanks for your comment. Which model of Nokia handset are you using? If you’re currently using a Lumia Windows Phone handset, the contacts will normally be synchronised automatically to Outlook.com. To access your contacts using an iPhone, simply follow the instructions on this page. If you’re using a non-Windows Phone handset, the best way to do this is probably still use the SIM card. You can use a nano-SIM adapter to place the nano-SIM from your iPhone into the old Nokia handset.
      Hope this helps!

    I have an iPhone 4 but I have a year left on my contract and I would like to buy an iPhone six without a sim, would it be possible for me to cut down my sim for the six or will vodafone be able to do that for me free of charge

      Ken replied:

      Hi Tom,
      It’s not possible to cut your Micro SIM down to a Nano SIM (the reason for this is the 0.09mm difference in thickness). The best thing to do would be to visit your local Vodafone retail store. They can swap your Micro SIM card over to a Nano SIM: it’s totally free of charge and will normally take no longer than 15 minutes at most.
      Hope this helps,

    Hi, I’ve just ordered a Giffgaff nano sim, and I needed a micro sim is there any chance id be able to get my money back, as it was payed on card, or any change of getting the bit that surrounds the nano sim? thankyou so much.

      Ken replied:

      Hi Alicia,
      Thanks for your e-mail. There’s no need to get your money back: simply order a free Micro SIM from the giffgaff website. Once the Micro SIM has arrived, use the giffgaff SIM swap tool to move your phone number & airtime credit over to the new SIM.

    Hi,
    I’ve just received a new microsim for a new phone, however I would like to keep my old number. I’ve tried ringing Orange and they said it was done and that I would receive a message within 24 hours to confirm this. However haven’t received any message and I still have the new number on the new phone. Any ideas? Or should I just cut down my old sim and put that in the new phone?

    Thanks

    1. Ken Lo
      Ken replied:

      Hi Alan,
      Thanks for your comment. The best way to change over to micro-SIM is to ask Orange to replace your SIM card (you can do this in an EE retail store and there should be no charge). It’ll probably be easier than ordering a micro-SIM and asking Orange to transfer the number to it. If you do want to go through with the transfer, it might be worth prodding customer services to make sure the request hasn’t been lost in the system.
      Good luck,
      Ken

      Hi Udanthaz,
      I’m really sorry to hear the problems with your Galaxy S5. If your SIM and SD card slot has become jammed, the best thing to do is either to get in touch with your mobile network operator or with Samsung support. It’s likely they’ll need to look at the phone (they may also need to replace some of the components).

    Hi

    I am 6 months into a 24 month contract with ee with a Samsung s4 and I don’t like the phone really, would like an I phone again. If I sold my Samsung n bought an iPhone out right is there anyway my contract with ee can be changed to a nano sim? N if not have u got any other ideas? Much appreciated

    1. Ken Lo
      Ken replied:

      Hi Karin,
      Yep, this certainly won’t be a problem! It’ll cost £10.20 to get your EE SIM card changed (you’ll need a Nano SIM for the iPhone 5/5c/5s). Follow the instructions here to get your SIM card changed.

    Hi Ken, I have recently bought a Samsung S5 to replace my old blackberry. I have followed the steps to trim the sim card to a nano size and found that the new S5 could only read the contacts from my sim but not able to connect to the network. What do you think could be wrong? The old sim card or does it just not like trimmed sim cards? Your advice is really appreciated.

    Thank You.

    1. Ken Lo
      Ken replied:

      Hi Ewan,

      Thanks for your comment. First of all, did you mean micro SIM in your message above? The Galaxy S5 requires micro-sized SIM cards (a nano-SIM would be too small for your phone). I would recommend asking your network for a replacement micro SIM. It’s a fairly easy process (especially as you’ve already transferred your contacts to the S5). The replacement micro SIM is likely to work more reliably (if it doesn’t, the problem will lie with your phone or network rather than the SIM card itself).

      Hope this helps,

      Ken

    Hi all,

    I’m using HTC ONE S (Micro sim)… now i want to use same the SIM card within other mobiles (like basic mobiles). However, basic mobiles only support normal size sim cards. How can I use my micro sim in basic mobiles? Should I replace my sim? OR is there any slats available on the market? Please let me know as soon as possible its great help to me
    Thanks in advance…

    1. Ken Lo
      Ken replied:

      Hi Suresh,

      Thanks for your comment. If you’re permanently switching your phone, the best thing to do is to ask for a new SIM card (ask your mobile operator for a standard size SIM card, or 2FF Mini SIM). This will work most reliably. If you’re regularly switching between multiple handsets, you can instead use a SIM card adapter. You can find a Micro-to-Standard SIM adapter at Amazon – the normal price is around £2. Please be aware that some handsets are incompatible with an adapter (see the guidance in the article above).

      Hope this helps!

      Hi Mury,
      Thanks for the comment. You’ll need to unlock your Galaxy S4 from MTN before switching to Glo. The easiest way to do this would be contacting MTN Customer Services. Apart from this, I’m sorry as I can’t provide any specific advice relating to Nigeria (I mainly cover the UK mobile market). For UK-specific info, this article shows how to unlock a Samsung Galaxy from UK mobile networks.

  62. Phil said:

    I’ve done exactly what you’ve said not to below! The phone is an xperia Z which I now can’t get to recognise my SIM card. Do you have ny ideas?

    Nano-to-Micro SIM adapters
    Once you’ve received an adapter, do be careful. You shouldn’t insert the adapter into a phone unless there is a SIM card placed within it. An adapter inserted without a SIM card could cause damage to your phone when it is finally removed.

    1. Ken Lo
      Ken replied:

      Hi Phil,

      Very sorry to hear this 🙁 It sounds as if the SIM card contact has been damaged by the adapter. Unfortunately, it might be a case of having to get in touch with Sony Customer Support. If the SIM card reader needs to be repaired, there might be a fairly substantial cost 🙁

      Hi Taylor,
      The Nokia N8 uses standard-sized SIM cards. Nokia strongly recommends against using an adapter so make sure you have a Standard SIM provided by your network.
      Hope this helps!

      1. Jason Bourne replied:

        Absolutely correct Ken the N8 will only fully function with the standard sim i.e. having the metal contact pad measuring 14.5mm long by 11mm wide.
        I am with asda mobile at the moment, they have sent me 4 combi sims the metal contact pad measures 11mm long by 8mm wide 55.17% smaller than the standard sim.

        None of them will allow me to access the internet my emails or operate maps, now I am left with worhtless phone which cost me £360.0 two and a half years ago.

          Hi Jason,

          Sorry to hear your problems using the Nokia N8 with an ASDA Mobile SIM card. There’s an article on All About Windows Phone discussing the problems using an adapter in the Nokia N8. I agree it’s incredibly annoying: the switch to Micro SIM was intended to save space inside a handset. However, I do wonder how much space is actually being saved (probably very little).

          Your original comment was actually posted here on a different article about Smartphone SIM Card sizes. Sorry for any confusion caused!

      Hi Jane,
      There are currently only four phones available using Nano SIM: iPhone 5, iPhone 5s, iPhone 5c and the Nokia Lumia 1520 (see our listing of smartphone SIM card sizes. As the choice of Nano SIM handsets is still quite limited, I would recommend following the instructions above and switching to Micro SIM. This will greatly increase the number of handsets available to you.

    I am currently on GiffGaff and I have a standard/micro sim however I have just purchased a new iPhone 5S. How do I order a new nano sim without having to report my sim as stolen.

    1. Ken Lo
      Ken replied:

      Hi Isaac,

      Thanks for the comment! The good news with giffgaff is that this is super easy. Start off by ordering a new giffgaff nano-SIM. Once it’s arrived, you can use the giffgaff SIM swap function to migrate over. This will transfer your account to the brand new nano-SIM including your phone number and the attached goody bag. The whole process should take just a few minutes.

      Hope this helps!

    You can cut down a Mirco sim to a Nano sim as I have done it twice in the last 2 weeks. I cut down an Ovivo sim to fit my 5S which was a bit hair raising but with the help of a file it was done. Easier was cutting down a giffgaff sim to go in a 5. The Ovivo sim meant cutting the metal contacts but the gg sim is smaller so only cutting the corner needed metal work. Being slightly thicker does not seem to matter in iPhones but I did give the sims a quick rub on a file. There are templates and guides on the internet and giffgaff. Care: Steady hand and nerves required – don’t blame me if it doesn’t work!

    1. Ken Lo
      Ken replied:

      Hi Bob,

      Thanks for the feedback! As you say: it can be done if you forget about the thickness difference. At present, the iPhone 5/5s/5c has enough engineering tolerance to allow you to use a slightly thicker SIM card. That said, in the future, I’m not sure this will be the case for all Nano SIM devices (e.g. if Samsung released a Galaxy S5 that used Nano SIM cards, the SIM card slot design could be different). In my opinion, the best solution would be to get a replacement Nano SIM – that way there’s nothing to worry about either now or in the future.

    Hi,
    My contract is due for a renewal/upgrade, when I contacted the network provider (t-Mobile) direct they cannot offer me the handset I want on the right tariff with a FREE handset, they are asking me to pay £200. Yet there are 2-3 online retailers offering the same tariff with a FREE handset on the same network. Can I take advantage of such offers and keep my number? Would I have to cancel the existing contract?

    Hi,
    Not sure if right place but posting in desperation. On taking delivery of a new SIM pushed in the micro by mistake. Now cannot remove from my Galaxy Ace. Any ideas?

  70. @OliNejad said:

    I rang orange and tried to transfer my sim from standard to micro to fit a Nokia Lumia 610. At first I was told I would have to cancel my contract, and take out a new one straight away. I responded by asking to be sent a micro sim to replace my own, which after being placed on hold for 3 mins, they did. Very easy but not straightforward. Be sure to say when you ring (hit the automated menu and keymash until you reach an operator) that you want a micro sim sent to you to replace your current contract sim. All should go smoothly.. Hope this is useful to some.

    Hello Ken

    I've recently inherited an iphone 4 (unlocked) & as I'm at the end of my current contract with '3' I'm looking around for a good sim only deal (my old contract came with a small basic phone which is now falling apart)

    I find the '3' coverage in my area not so good when indoors so I'm not overly concerned by ending with them even if they are the cheapest deal.

    I have noticed though that '3' (& most of the other carriers), when offering 'SIM ONLY' contracts, differentiate between an ordinary sim contract & an iphone sim contract, charging more for the iphone sim contract (30 day & 12 months)

    I know the iphone 4 (& 4s) require a smaller micro-sim but what's to stop me taking out a cheaper ordinary sim only contract & then cut it down to size using a sim cutter to make it fit my iphone 4.

    I understand that the only difference in the two types of sims is in the plastic surround with the chip being the same in size & functionality.
    ……Is that too simple an option or is there something I'm missing?

    1. Ken Lo
      Ken replied:

      Hi Tony,

      You're right: there is no difference in the SIM except from the amount of plastic surrounding the chip. The tariff will be identical too between SIM and micro-SIM versions (except from O2 which offers "Visual Voicemail" on their iPhone-specific tariffs). As far as I'm aware, the main mobile operators have done away with the distinction between SIM tariffs and Micro-SIM tariffs so there shouldn't be any differences any more. Let me know if you spot any though.

      Hi Shree,

      It should be possible to do this – however as both of your devices are on Android you could alternatively synchronise your phone book with Google. When you log in to your Google account from the Note 2, all of your contacts should automatically appear. Alternatively, Samsung also provide some software called Kies which can do this for you.

    Trying to switch from dongle sim to micro sim for ipad has become a nightmare. I am still on contract with orange for dongle £5 per month which I want to keep as I only use infrequently. Different people at Orange give different answers, one says I can keep existing plan but has failed to do the switchover, whilst others say I must switch to a specific ipad plan which is of course more expensive. I now seem to have tow options, try cutting down my card to see if it works or just waiting till the end of contract (January) then moving to another provider.
    One guy at orange even told me that Apple set the tariff so they can;t do it at the same rate as my dongle which sounds a load of c……s to me.
