    Hi Ken,

    I want to move from my current contract with EE to a giffgaff SIM only deal. I’ve got the new SIM and have obtained a PAC code, but EE told me I have to give a month’s notice when I end my contract. My usage resets on the 2nd of the month. If I active the PAC code now, do you know if I’ll still be charged by EE for October?

    Thank you!

      Hi Jess,
      Thanks for your comment. You’re liable to pay 30 days worth of charges from the moment when you tell EE you’d like to leave their network. So for example, if you give them notice on September 16th, you’ll need to continue paying until October 16th. This is regardless of when your phone number gets ported over to giffgaff. So if you’d like to get the most of your EE contract, you could continue using it for the time being and you could then port your number over to giffgaff in the second-week of October.
      On your final bill, EE will charge you a pro-rated amount. So it doesn’t really make a difference when your allowances refresh (you’ll just be charged for part of the final month).
      Hope this helps,
      Ken

    HI Ken

    Great site. Many thanks for the clear and concise information. I’m going to buy a OnePlus2 phone and will transfer from 02 to Giffgaff. You have already provided very clear info so no need to repeat it for my sake (!).

    I’m going to buy a OnePlus2 smartphone. It looks great from a tech point of view and significantly cheaper than the mainstream phone manufacturers (Apple, Samsung, Etc).

    Any thought on this firm ?

    Kind Regards, Nick

      Hi Nick,
      Thanks for your comment and glad the website was useful! Unfortunately, I haven’t had any direct experiences of the OnePlus2. I had a couple of friends using the OnePlus One (general feedback was it was OK) but not sure I know anyone with the OnePlus Two. Before you buy, I would however also look at some devices from Motorola and Huawei (they also offer good phones at a very competitive price).

    Hi, I have been having troubles trying to contact Lycamobile about my PAC code and they are just keeping me on hold every time I call them. I am trying to move to Giffgaff but I want to keep my old number but Lycamobile are just making things very hard. Is there any way that I could possibly do to receive my code. I have called different Lycamobile numbers as well but the result never changes. I hope you can help.

      Hi Denty,
      Thanks for your comment. Unfortunately, your old SIM card on Three will now be inactive and so you won’t be possible to re-use it again. You can however order a new SIM card from Three, and of course you can transfer your number to this SIM card through the normal PAC Code process.

    Hi Ken,
    Apologies if this is stupid question or it has been asked before: my daughter has a Nokia phone on T-mobile monthly bundle – we want to get her a SIM Free Moto G and also transfer to a GiffGaff SIM so we can use their goodybags, which seem better.

    I can see that it is straightforward to get a PAC from T-Mobile to do this but my question is: what happens if we buy the Moto G from Three – which is cheapest route according to your report – do we have to transfer from T-Mobile to Three and then from Three to GiffGaff?

    If this is the case, would it be better to buy the phone SIM Free from somewhere else online?

    Many thanks,
    Alex

      Ken replied:

      Hi Alex,
      Thanks for your comment. When purchasing the Moto G from Three, it’s provided to you on an unlocked basis. Hence, if you like, you can immediately use a SIM card from giffgaff inside the handset (there’s no need to actually use the Three SIM card). This way, you’re able to transfer your phone number directly from T-Mobile to giffgaff. If you’d like to use the SIM card from Three, then you can of course do a transfer from T-Mobile –> Three followed by another transfer from Three –> giffgaff.
      Hope this helps,

    Hi Ken, lots of great information here, thank you.

    I tried to ask this question at the weekend, but suspect it didn’t post properly.

    If I have an old Three phone with PAYG credit on it (which I want to use up) and a new phone with a sim from Giffgaff (which I intend using straight away) is there any time limit on how long I can wait before transferring my old Three number to my new phone? You’d normally transfer your old number to your new phone almost straight away, but I suspect it could be a couple of months before I would want and need to do this.

      Hi Colin,
      Thanks for your comment and sorry for the delay in getting back to you!
      There’s no time limit on transferring your number: you’re able to do this any time you want. So it’s definitely fine to use up your credit on Three before moving the phone number over to giffgaff. Indeed, I normally recommend against transferring your phone number immediately to a new network (it’s always worth spending a bit of time to ensure the new smartphone & network is working properly… it’s much easier to cancel the transfer if you haven’t yet moved the number over).
      By the way, if it’s too much hassle carrying round two separate handsets and if you’re already paying for a goodybag on giffgaff, you can expedite the process of using up your credit by donating the old credit to a charity you support (better than leaving this money in Three’s coffers!). See here for more information.
      Hope this helps,

    Hi there I am thinking to transfer to giffgaff but may need my PAC Code to do this as I want to also keep my number. O2 is costing me a lot of money through top up and I was wondering if I could change to giffgaff so I can get free internet, free mins and free text that wouldn’t cost me a lot of money

      Hi Bhavini,
      Yep – you will need a PAC Code to move your number from O2 to giffgaff. You can see the link here for more information. Unfortunately, giffgaff doesn’t give you free allowances automatically with the top-up (though you will get free calls & texts to other giffgaff members). Most giffgaff members choose a buy a goodybag: the total monthly cost will often still be less than using Pay As You Go on O2. Do have a look at my review of giffgaff if you have any further questions!

      Hi Heather,
      As per Ofcom’s General Conditions of Entitlement, Lycamobile are legally required to issue you with a PAC Code within two hours of your request. If they’re unwilling to do so, please remind them of the legal responsibility. If you’re still having problems getting the PAC Code, please do drop me another comment with the reason they’ve specified for refusing the request. I’ll then try to investigate a bit further!

    Hi Ken

    I have recently switched from Orange to GiffGaff, after coming to the end of my 24 month contract. I have paid a final bill already, but a month later they have billed me for another month’s line rental. I know their terms and conditions state that you must give 30 days notice to cancel a contract, even once it has run it’s term, but for that 30 days I would expect to continue to receive service. But I was lead to believe that by porting the number with a PAC code, that this would cause the contract to terminate immediately that the number had been ported away from them, as the Orange SIM was no longer linked to my number and I was not receiving any service. Do I really have to pay for a month’s “line rental” in a month where they did not supply me with a “line”?!

    Regards

    Lucy

      Ken replied:

      Hi Lucy,
      It does really suck but unfortunately that’s the way things currently work with the 30 day notice period 🙁 One way you’re able to get around it is to give your notice in advance. Alternatively, you can request your PAC Code and to only use the code just before it expires (other readers have done this in the past as you’re still able to use the old line for almost one month). I’d really love to be able to change the system but I suppose it’s an effective way for the mobile networks to take their last pound of flesh before you switch to a rival. So certainly worth filing a complaint with Orange – with enough feedback, hopefully the networks will change their policy in the future.

    Hi Ken,

    Thanks for all the information provided above. I wish I had read it before I started the transfer from 3 to giffgaff as it’s Saturday now and so my old number will not transfer until Tuesday. Should have transferred between Monday-Thursday!
    I have a couple of questions:
    – My new giffgaff SIM has now been activated and everything is working fine. Can I put my old 3 SIM back in my unlocked Nexus and use it until Tuesday?
    – If I do this will I have to go through setting up the Internet connection again do you know?

      Hi Georgie,
      Thanks for the comment! It’s no problem at all requesting your number transfer before the weekend: you’ll still have coverage on your old Three SIM card until the number transfers over. So yes, do feel free to stick the Three SIM card back into your unlocked Nexus smartphone. When doing so, it might be necessary to restore Three’s APN settings. On Tuesday, when your number transfers over, you can put the giffgaff SIM card into your Nexus device and restore giffgaff’s APN.
      Hope this helps!

    Hi Ken
    I have a 30 day contract with Talkmobile which I gave notice to quit on 10th Nov ’13. I had an acknowledgement that the contract will end on 10th Dec ’13 which was fine. I asked for a PAC yesterday 1st Dec so I can xfer to Giff Gaff SIM only and they said they can only do one or the other i.e. PAC code or cancel contract and implied that the contract will have to run for a further 30 days from issuing the PAC code. Surely this can’t be right? If I use the PAC code on the 9th Dec and Giff Gaff xfer it over the next day, surely the contract will end then? If not, how can I use up another months contract allowance without a phone number?
    Thanks

      Ken replied:

      Hi Trefor,

      Your Talkmobile SIM is 30-day rolling contract (so you need to give 30 days notice when leaving the network). At present, your account is scheduled to close on Tuesday 10th December. If, at this point, your phone number is still on Talkmobile then you will lose your phone number forever (there’ll be no way of recovering it and having it sent overt to giffgaff). Hence, you’ll need to make sure your phone number has been transferred before the 10th December.

      In theory, you could decide to wait until the 9th to use your PAC. However, I’d recommend porting your phone number as soon as would be possible. Bear in mind, things could go wrong or the transfer could be delayed. Also, number ports won’t happen over the weekend (so there are no ports happening on Sat 7th or Sun 8th). If you contact giffgaff on Friday 6th, then your port should be completed on Monday 9th.

      Hope this helps!
