O2 PAC Code: Keep Your Phone Number When Changing Networks

Whether you're joining O2 or leaving for a different network, it's a straightforward process to keep your old phone number.

O2 PAC CodeIf you're leaving O2 and joining another network or if you're leaving another network in order to join O2, it's easy to keep your old phone number. All you need to do is to request a PAC Code: it's totally free and the entire process of transferring your phone number should normally take no longer than one working day.

For detailed instructions, please choose the option that best applies to you:

Leaving O2 For Another Network

O2

If you're leaving O2 and joining another network, you can take your phone number with you.

Start by asking O2 to issue you with a PAC Code.

If you're a Pay Monthly customer on O2, you can request a PAC Code by calling 202 on your O2 handset. Alternatively, dial 0344 8090202 from any other phone.

Alternatively, if you're a Pay As You Go customer on O2, request a PAC Code by calling 4445 on your O2 Pay As You Go handset. You can also call 0344 8090222 from any other phone.

You can request a PAC Code over the phone at any time during O2's opening hours:

Monday - Friday8.00am - 9.00pm
Saturday8.00am - 8.00pm
Sunday8.00am - 6.00pm

It's always free to get a PAC Code from O2 (it's your legal entitlement). After getting your O2 PAC Code, you'll need to provide it to your new network operator. For detailed instructions, please select your new network operator from the dropdown menu below:

Your new network provider:

Joining O2 From Another Network

O2

If you're joining O2 from another network, you should ask your old network to provide you with a PAC Code. The PAC Code will allow you to transfer your number to O2.

After getting the PAC Code, you should order your new handset or SIM card directly from O2's website. For more information, please select the type of tariff you're wanting to move to:

Once Your New Phone Arrives...

Once your new phone or SIM card arrives from O2, turn it on and make sure everything's working properly. If you need to return or change the new handset/SIM card, please do this before you transfer your phone number.

Once you're happy to continue with the transfer, your PAC Code should be entered on O2's online form. Alternatively, you can also provide your PAC Code to O2 over the phone:

If you're joining O2 Pay Monthly, you can submit your PAC Code by calling 202 on your O2 handset. Alternatively, call 0344 8090202 from any other phone.

If you're joining O2 Pay As You Go, submit your PAC Code by calling 4445 (0344 8090222 if you're calling from another network).

Providing your PAC Code to O2

The PAC Code should be submitted through a form on O2's website.

Once you've provided your PAC code to O2, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays).

    Hi I’m currently with O2 and my monthly contract is finishing in the next few weeks. If I got the PAC number today off O2 would it be possible to switch my number to a lyca pay as you go sim today? If so what would happen to my currently existing O2 sim?

      Hi Dee,
      Thanks for your comment. You can use your O2 PAC Code at any time, but when you do so the existing O2 SIM card will stop working. You’ll then be sent a final bill by O2 with an early termination fee covering the final few weeks of your contract term.
      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 Ken

    I apologise for picking up on an old threat, but you seem to be so knowledgeable so I am hoping that you can help my confusion!

    I am out of contract on O2 and would like to get a new phone/contract with EE.

    My question is whether it is necessary to have an overlap of a full month with both contracts running in order to keep my number?

    This seems to be the case from what I have read, because I seem to have to request my PAC from O2 and provide that to EE before I can terminate my contract with O2. This would mean that for one month, I will have to pay almost £40 to O2 for the one month’s termination notice, in addition to £35 for the new contract with EE.

    Is there any way to avoid this duplicate cost that you know of? I really want to keep my number, but feel hesitant in having to pay £40 to do it!

    Many thanks in advance

    Victoria

      Hi Victoria,
      Thanks for your comment. On your current contract from EE, you need to provide 30 days notice before leaving the network. There are two ways you’re able to minimise the overlap between your old and new contracts:
      1) You can ask for a PAC Code today and you can start your contract with O2 in about 2 or 3 weeks time (this is to minimise the 30 day overlap). You can then give your PAC Code to O2 once the contract there has started. In general, I wouldn’t choose to leave it too close to the end of the 30 days (the reason being you’ll probably want to test out things on O2 before moving your number over e.g. in case the coverage on their service isn’t exactly what you’re expecting… it’s much easier to cancel your O2 contract if you haven’t yet moved your number over).
      2) You can give EE some advance notice about the date on which you’d like to end your current contract. You can then time the start of your new O2 contract about one or two weeks before your EE contract ends. You’ll need to obtain and use a PAC Code before your contract on EE ends.
      Hope this helps,
      Ken

      Hi Morgan,
      Thanks for your comment. If you call 789, you’ll reach Virgin Mobile’s customer services department. You can then speak to a customer services advisor to give them your PAC Code. Unfortunately, I don’t believe they have an automated service for you to provide this code.

    Hi, i,ve recently tried to move my number from Sainsburys mobile to O2, I got my pac code from Sainsburys by txt it only gave me couple of days to use it, I had till lunch time on the 11th of Jan to use it by. I spoke with O2 the morning of the 11th I was given a temp number to transfer my old number onto and gave them my PAC code I was told it would take a couple of days to get my sim card in the post. a couple of days later nothing came and when i rang O2 back they said it could take unto ten day.10 days passed and I called back, I was told it hadn’t been processed correctly the lady who originally proceed my pac code had entered the pac code wrong, and that I would need to get a new pac code from Sainsburys. Sainsburys have now stopped trading on the 15th of January and I’m being told I might have lost my phone number . This was a mess up by O2 and the number i was trying to transfer is my business phone number which is very important to me and nobody is helping me i’ve spent hours on the phone to O2 and Sainsburys and no one is helping me, I don’t know how to get my number back, What can I do?

    Hi.

    I think I made a stupid mistake. I transferred my number to a SIM-Only deal from O2 to Three but I did so without activating my SIM first. I had a phone on contract with O2 but the contract has ended so the phone is mine now. I’m not sure if I need to get it unlocked first before using my Three SIM. I don’t have any network coverage on my O2 SIM and I’m unable to activate my Three SIM. Help!

      Hi Rhonda,
      Thanks for your comment. It may be necessary to unlock your handset from O2 before you’re able to use it on Three. I believe that O2 will typically lock iPhones on their network – are you using an iPhone or is it a different device? There’s more information about how to unlock your handset here (you may also find it interesting to read the guide on unlocking an iPhone and unlocking a Samsung Galaxy). It should be free to unlock your handset from O2 as you’re a Pay Monthly customer.

    I missed a payment on my 02 contract and they seemed to have terminated it, I went online to sort it out and the website says that my account for that phone/number is no longer there, which also means I can’t pay that bill. I wanted to move to EE but keep my number, but if 02 don’t have that account anymore is there any way of doing this?
    I fear if I phone the customer services and get through to an advisor, I will get an earful about not paying the latest bill, despite them giving me no way to actually pay it (I can’t pay a bill if the account is no longer there)

      Hi Jess,
      Thanks for your comment. In this situation, I’d really recommend giving a call to O2 Customer Service (dial 0344 809 0202 from a landline if you aren’t able to use your O2 mobile). The important thing is getting up-to-date with payments as soon as possible so you’re then able to take your phone number to EE.

    The transfer from 02 to vodafone, my phone can dial out but nobody can dial me or text me, the transfer date was today but I’m without full service on my old 02 SIM and on my new Vodafone sim, I’ve called Vodafone several times to be promised different things and told different stories but as yet I’m still without a useful phone. Do you know if keeping the phone switched off is useful as one Vodafone representative told me it was my fault for having the phone on . . . I’d never been told to switch it off

      Hi Agne,
      Thanks for your comment. It depends on how you’re planning to use the EE network. If you’ve bought a new handset from EE, it’s not necessary for that phone to be unlocked (it will work straight away on the EE network). If you’re planning to use an EE SIM card in your existing O2 handset, you’ll need to make sure your handset is unlocked. For more information, see my guide on mobile phone unlocking as well as the articles on unlocking an iPhone and unlocking a Samsung Galaxy.

    Hi, I informed EE that I was leaving and requested by pac code which they sent in the post. Before I had even used the code EE charged my account £36 for requesting the code and giving them my 30 days notice.
    When I had originally contacted EE they never informed me of this charge and then went on to say that it was because I had requested the pac code I had to pay for it.
    After discussions with them they finally agreed to refund me the money as at no point was I informed of this charge.
    I wasn’t in a contract with them and on the bill it said penalty charge??????
    I am now worried that although i am receiving texts and phonecalls on my new O2 phone, my old phone is still able to call out as I have tested it and I don’t want them to charge me for it.
    EE is a nightmare!!!!!
    I’m still waiting for the refund so watch this space as to whether I will have to call them again!!

    Thanks for the info though it has helped.

      Hi Gerry,
      Thanks for your comment. It’s iD Mobile that’s now responsible for the provision of your service (your phone number has already left the O2 network). Unfortunately, this means you need to further liaise with iD Mobile to resolve the problem. I know this response won’t provide you with much comfort (it’s just that iD Mobile are the only people who are actually able to see your account). If you want to escalate the issue, I recommend you make a formal complaint in writing to iD Mobile. This should hopefully help you in getting the situation resolved as quickly as possible.

          I’m afraid I can’t advise on legal entitlements with regards to a phone number (there isn’t a set rule or compensation scheme for things such as this). You could probably check directly with the Ombudsman or Ofcom but I’m also not totally sure if they can give you an answer. Your best bet would probably be to complain directly to iD Mobile – if necessary, you can escalate the issue upwards from there. Really sorry I can’t give you any more detailed advice than that! 🙁

      Hi Steff,
      Thanks for your comment. If you’d like to stay on T-Mobile’s Mates Rates, you’ll need to keep the T-Moible account open. If you were to transfer your phone number from T-Mobile to O2, then it would close the account that’s open at T-Mobile and you would need to later sign up as a new customer on EE (T-Mobile is no longer available to new customers joining the network).
      If you simply want to unlock the handset from O2, you can do this with a free O2 Pay As You Go SIM card. There’s no need to actually keep the number assigned to the O2 SIM card: simply use it for unlocking then go back to your normal T-Mobile SIM.

    I switched my network from T-Mobile to O2 via CarPhone Warehouse on 19/11/14, receiving my PAC code on the 19/11 and thus made O2 aware of the pac code during the online transfer. Received my new O2 sim on 20/11 around midday switching sims and noticing my network had changed correctly to O2.

    However, today I have received a final bill from my original provider (T-mobile) for £238 as on the morning of the 20/11, I used my phone to make calls, emails, browse the internet and watch a couple of video’s. I was unaware that I would be charged for usage by T-Mobile on the 20th and was not made aware by T-Mobile that this could happen. What options are available to me, do I have any legal recourse as this is a bill I simply cannot afford.

    Thankyou for your replies as this is a deep concern to me.

      Thank you for your comment and sorry to hear about the problems you’ve experienced with T-Mobile. It is rather ridiculous they’ve charged you £238 for only half a day of usage: what’s their rationale for making such a charge? What tariff were you on when this happened? It would seem reasonable for them to charge a pro-rata rate for your final month of usage but there’s no way the final bill should come to £238. I’d certainly lodge a complaint with EE: hopefully this should help to get the bill revised as quickly as possible.

      Once you have the PAC Code, it’s possible to use it to move to any network (hence you could use it for EE or for any other network).

    I transferred a number from a payg 3 (three) account to O2 Contract. Its been 10 days now and still no incoming calls. O2 are saying they have requested the porting files again and are waiting and cant do anything until they receive these.

    O2 made me change my SIM/disconnect me for 4 hours, unaccountable number of problem solving requests still no joy.

    Any advise?

    THANKS

    What about any credit on the SIM you are transferring to? I have a 3 PAYG SIM with some credit, and want to transfer the number from a O2 PAYG SIM. Once the number is transferred to 3, will I still have the credit from the previous 3 number?

    Also, what happens to the previous 3 number?

      Hi David,
      The SIM card on which you’re transferring your phone number to will retain any credit it had before the incoming transfer. So any credit currently on your Three SIM card will still be there after the transfer is complete.
      Hope this helps!

    Hi Ken,
    Thanks for info here. I’m having a nightmare porting from T Mobile (EE) to O2. Port requested on Friday scheduled for Monday 6pm. Old number cut off on Friday so I have no means if my business customers getting hold of me on my kniwn number. Called O2 who are currently giving me the run around and no help whatsoever. They ofcourse are blaming T Mobile. Any advice you can offer would be gratefully appreciated. Thanks. E.

      Hi E,
      Sorry to hear about the problems you’ve experienced transferring a phone number from T-Mobile to O2. Based on your description of the problem, the problem has occurred on the T-Mobile end (O2 are right in blaming T-Mobile). T-Mobile should keep your number active until the transfer actually happens: they shouldn’t disconnect it or end your contract early. A transfer through the PAC Code system should simultaneously close your T-Mobile account whilst moving the number over to O2. Hence, I’d recommend calling T-Mobile Customer Services (0845 412 5000) – they’ll be best placed to help in solving the problem.
      Good luck,
      Ken

    Having switched from O2 to 3 without problems I have noticed that my phone (a moto G) shows its phone number as being the original number assigned to the 3 SIM rather than the phone number I ported from O2.

    Is there anyway to ensure that the correct number is displayed for my phone?

      Hi Ken,

      Thanks for your comment. Is this a problem with your Caller ID (the number which shows when you make a phone call) or a problem on the handset itself? For caller ID, the best thing to do is to contact Three Customer Services (call 333 from your Three handset). For the latter (a problem on your handset), a quick restart will normally solve the problem (you may also need to re-register through apps such as WhatsApp).

      Hope this helps!

        Hi Ken,

        Thanks for the reply. I was able to edit the SIM number on another Phone (Samsung Galaxy ACE DUOS) by going to Contacts/Settings/Own Numbers and editing My Number.

        So it now shows up correctly on both the phone and caller ID.

    Hi Ken, I ported my very nice number from O2 to Vodafone mid Jan. Since I have not been able to receive any calls from any other provider or landline other than vodafone and no texts except from Vodafone. It has been very difficult 8 weeks with what amounts to a zero service. I am able to text and dial out and my nice number is shown as the caller, it just dosent work the other way. I have been in almost daily contact with vodafone to get them to resolve the issue, they havent I just go from one tech to another and empty promises that it will be resolved. I can hardly believe that this is a strange and never been encountered problem in the whole of the world. I have come to end of tether and have complained to Ombudsman. Thats the background. If I should go down the route of severing my contract and requesting my PAC number is it likely I would have the same problem with another provider…. has my number/code been scrambled!

      Hi Jem,

      I’m really sorry to hear your experiences about transferring a phone number from O2 to Vodafone. It’s a rare problem as most PAC Code transfers happen without any issue. Was your phone number originally issued by O2 or was it issued by another company? Your phone number will come from the block of numbers issued to your first mobile network (see the full list on OFCOM’s website). For instance: 07734 is O2, 07735 is Three, 07741 is Vodafone, etc. Then, somewhere along the line, there’ll be a database of phone numbers transferred to a different mobile network. For instance, the database might say that 07734 555 555 is now on Vodafone rather than O2. The problem with your incoming calls & text messages likely originates from that database.

      Either way, Vodafone is the responsible party which should resolve this issue. I hope the issue can be solved promptly for you, with the involvement of the ombudsman. Please do get in touch and let me know how you get on with Vodafone.

    I am switching from O2 to Orange. My new phone arrived last Thursday. I contacted O2 and was given a PAC more or less immediately. First thing Friday morning, the new phone had been activiated so I rang Orange (150) and gave them the PAC to get my old number transferred. I was told that my number should transfer between 10am and 3pm the following day….I’m still waiting, it’s now Tuesday pm and nothing has happened. I did think well maybe he hadn’t realised that the following day was saturday and these things didn’t happen on a weekend. But surely something should have happened by now! I know your advice will be ring Orange, but an hours wait on the phone, while I’m at work isn’t ideal!

      Hi Lou,

      Thanks for getting in touch. You’re right in saying that phone numbers don’t transfer at the weekend, so a request submitted on Friday morning should go through on Monday (Tuesday if you miss the cut-off time). As your number still hasn’t transferred as of Tuesday evening then it seems like Orange have failed to transfer your number correctly. I’m afraid my advice would indeed be to contact Orange… though fingers crossed the wait shouldn’t be as long as an hour. Orange are the most likely people to know what’s happened: i.e. whether your request was correctly entered into the system, the status of your number port, etc.

I phoned them back 5 hours later and customer services told me that it had taken place and I was phoning from my old O2 number (I as using my new phone) this seemed strange as my old O2 phone was still working.

    Good morning Ken, Great article btw extremely helpful. I am in the process of migrating 4 of our business phones from o2 to EE via carphone warehouse. I was contacted by Carphone warehouse this morning telling me our main number (the bosses num for 20+ years) is not supported by EE as it is an “0777” number, and we need to change it? I then contacted EE direct and they seem to think all they need is a PAC code and any number is fine, my question is have you heard of this problem before? and what one of these companies is likely to be telling me porkies?

      Hi Jim,

      Thanks for getting in touch. As far as I’m aware, there is no reason why EE couldn’t support a number beginning with 0777. If you take a look at this link (it’s the OFCOM database for mobile numbering), you’ll see that numbers beginning with 0777 are just normal mobile numbers like any other. Indeed, Orange (now part of EE) was even assigned the 07772, 07773 and 07779 number ranges for their own customers. Given this, I believe I believe it’s highly unlikely that EE would have any problems using an 0777 phone number.

    Hi Ken,

    I used my PAC code yesterday to transfer my number from O2 to Orange. It is now just over 24 hours later. When I call from my new phone, the number shows up as the transferred number as expected. However when I call to the trasferred number from another phone, the call still goes to my old phone with my old O2 sim. Is this normal? Will it be resolved if I wait a few more hours?

      Hi Paul,

      I believe this problem may occur temporarily – your old network (O2) still needs to release the number to Orange. On the Orange side, they’ve changed the “Caller ID” number to the number you’re transferring from O2. If this problem isn’t resolved after a few hours, I’d recommend getting in touch with O2. Let me know how it goes!

      Hi Sattam,

      The reason for this is simply because Vodafone and O2 are different companies: since you've paid your money to Vodafone so there is no reason why O2 should honour that airtime credit. Unfortunately there isn't a mechanism whereby airtime credit can be transferred between companies: instead you'll have to use it up before switching network.

    1. Phone boffin replied:

      Kirsty, there’s no way on earth that Vodafone or any other company will just “cancel” without you knowing.
      That’s the whole reason you have a “contract” which is legally binding on both sides. The only reason they can null your service is if you’re not keeping up with payments and/or using the device/contract for things that go against the contract you agreed to.
      Of course, someone may’ve impersonated you to cancel the contract, maybe even if someone else pays the bill they might have cancelled it without telling you, but as terrible as Vodafone are, they won’t “just cancel it” without good reason.
      If you want to change to another service provider, just sticking a sim card into the phone may not work as the phone needs to be unlocked from some networks.

      Unfortunately when you port a number, you cannot transfer Pay As You Go credit so the £10 credit has unfortunately been forfeited. You could ask O2 to refund the £10 as a gesture of goodwill I guess, but I'm not sure they have to give it back to you. I'm not a lawyer though…

I suspect you'd have to pay for the rest of the month although you'll lose service once your number has moved over to O2. However, if you wanted them to switch the number you might be able to ask T-Mobile Customer Services to do that for you (let us know how you get on!)

      I think it's worth mentioning here that you don't save *any* money on your monthly tariff by taking your plan out now. You will only save money on the upfront cost of your handset. See my guide to VAT increases for more information.

    I’m trying to move from Orange to O2 and Orange staff are being very uncoperative by cutting me off etc.

    Yesterday my mum went to the Orange shop and they put us through to a man in India. He said that he would phone us back between 12:30 and 1:00 p.m that day it is now 2:59 the following day and we have still not heard from him, when my mum was talking to him in the shop he said that there was a queue of 600 people waiting for PAC codes.

    I have advice for people changing networks:

    DO NOT CHANGE TO ORANGE

      Hi pepp,

      There is no need to turn your phone off during the transfer process. You can keep using your Vodafone phone/SIM card as normal until the transfer to O2 goes through. The transfer can still happen if your phone is on.

    Hi Ken, I am a little bit confused and found on the internet you would give me a good & helpful advice.

    I am on the last month of contract with THREE. I wanted to upgrade and stay with THREE but they do not have a handset which I want to upgrade to. I am deciding to finish this contract and do not upgrade but I want to keep my current telephone number. I know that to go to pay as you go I just need to speak to THREE's advisor that I want to just move to pay as you go.

    The thing is that I want to get a contract with O2 now because they have exact handset that I want. Confusion starts now because I have no idea how to transfer my number from contract with THREE to contract with O2. What I have found is that there are 3 steps of this ! First : I need to get my number transferred to pay as you go at THREE and then obtain a PAC and transfer my number to O2 pay as you go and then to O2 contract ….. Is this right??

    please help me !! thanks so much

      Hi Kamil,

      Thanks for your comment. No, there is no need to transfer to Pay As You Go first. You can go straight from a Three contract to an O2 contract. There are step-by-step instructions available for this.

      Hope this helps

    Yo,
    I recently got a new phone, and changed networks to Orange (contract) from O2 (pay as you go). I didn't get a PAC code in order to take my old number with me (I'm already regretting that decision), and I am now officially with Orange. Is there any way that I can still transfer my old number onto my new phone, or will I have to start the process of telling all my friends and family my new number?
    Cheers

      Hi John,

      Providing you still have the Orange SIM card and the phone number hasn't been disabled, I think Orange Customer Services should still be able to give you a PAC Code to transfer your phone number.

      Hi Sally,

      Sounds like the number hasn't transferred over yet. Have you given your PAC Code to o2 and waited 2 days for the transfer to happen?

    I'm switching from 02 to orange. I have had my pac code through and have contacted orange and given it (pac code) to them. I currently have a different number from the new orange sim, but they said it can take 3 days to switch (due to the weekend most probably Monday). They told me to have my mobile off – but which sim/phone do they mean. The new orange one or my 02 one? my contract with 02 ended on Friday and I cancled it a few days before. They said for the pac to work properly my mob needs to be off, but I don't get which one they mean?

      Hi Katy,

      I'm not sure… you'll have to ask them for a clarification of what they mean. As far as I know, when the transfer happens you will simply lose signal on your old phone. For me it happened overnight so on the Monday morning when I woke up and turned my phone on, my old phone stopped working and the new one had the existing phone number.

      My advice is to reboot your new phone when you lose signal on your old one. I think this should be sufficient.

        Keep your new phone/sim switched off during the switchover period.

        Switched from 3 to Vodafone yesterday. Vodafone told me keep the Vodafone mobile/sim off between 11am and 4pm. And don't switch it on until after 4pm, even if signal is lost on the 3 phone/sim before then.

        With regards to the old phone – they didn't specify, only that it's important to switch off the new phone. Going to just keep both off – easier…

    Hi, I got a new SIM with o2 and requested a PAC code from Orange so I could keep my number. Orange said they'd send it in the post for me.
    I put the new o2 SIM in the mobile I'm using so that I could get it set up ready for when I receive the PAC code. The SIM said it had been activated and it appears that I now have signal and can use the SIM for calls and texts – but obviously on a new number that I dont want to use. Now that the SIM has been activated will I still be able to use the PAC code, SIM and keep my number? or have I screwed up by putting it in the phone?

      Hi Liam,

      Nope! Spot on… that is exactly what you need to do. You need to activate your new SIM card & phone number before you can even use your PAC code! Once it arrives in the post, call O2 customer services and give them the PAC Code. They'll handle the porting for you.

    Hi

    I’m in the process of dropping O2 because of their 500MB cap. I plan to get a Voda £20/mth iPhone SIM, cut it down to MicroSIM size and put it in the iPhone 4.

    Voda ask you for the PAC code when you’re placing the order. Is this likely to cause me some downtime between them activating the code and me receiving / using the SIM?

      Hi Rob,

      I’m not sure. If Vodafone start the porting process before you recieve your new phone/SIM there is the possibility your number could be transferred over to the new SIM whilst that SIM is still in the post. I’d give them a call and enquire.

      Cheers

    Hi Ken,

    I have a dilema. I have recently taken out a contract with O2 but have my business number with Virgin. I have asked Virgin for my PAC to transfer the number accross and was given this imediately! But they did say that as soon as I gave my PAC to O2 then the service with Virgin would be terminated. So as fara as Virgin are concerned I will be without contact with business clients for 48hrs. However when I spoke with O2 they said this wasn’t the case. It will take 48hrs to give the PAC to the Portal company who transfers the numbers but in this time my number will still be with Virgin & working & there will be maybe 1 hour while numbers are being transfered after 48hrs where there will be a break in the service to my business number but that is all. WHICH IS TRUE? I dont want to do anything until I am sure about how long I will be without the use of my business number!! Thanks

      Hi Mal,

      Thanks for your comment. O2 are right here: I recently had a similar experience switching from O2 to T-Mobile. Your Virgin SIM card will continue to work even after you have given the PAC code to O2. Once your number has been ported over to O2 (and not until then), your Virgin SIM card will be disabled. My number transfer happened overnight so I had no significant downtime at all.

      Hope this helps 🙂
