Switching from T-Mobile to EE? It's a straightforward process to keep your existing phone number.

Step 1: Order your new phone or SIM card from EE's website

As a special case, customers of T-Mobile won't need a PAC code when switching to EE. Instead, it's possible to upgrade directly to EE. As part of this upgrade, you'll gain access to EE's 4G network

Start by ordering your new phone or SIM card using the EE website. Please select the type of tariff you're intending to move to:

  • Hi Ken,Am currently with T-mobile on a contract thats just finished.Decided to upgrade my phone & found the best deal was on the internet.New phone arrived yesterday & I phoned T-mobile to ask for my PAC code & this was duly given to me.This morning phoned my new provider EE & was advised as T-mobile & EE are now essentially 1 in the same EE are NOT able to accept the PAC so I m stuck with the new number,however they advised I could go & buy a SIM only deal & give my PAC code to the new supplier ( say O2) then after a month cancel & ask for the new PAC & then & only then will EE be able to accept this PAC & move my old number to my newish phone.Seems a long winded way ,not to say expensive(1 month will be paying twice ) route to follow,is what I ve been told correct?

    Thanks

    • Hi Jim,
      Thanks for your comment. You’ve signed up with EE as a new customer on Direct Mobiles (EE are obviously a little unhappy as they need to pay a commission to Direct Mobiles for every new customer referred to their network). It’s for this reason they would have preferred you to upgrade an existing customer on their network. You’re being asked to transfer off the network and then back onto it as it would make EE’s numbers look a lot better (they’d be able to record this as a new customer acquisition).
      In reality, it shouldn’t be necessary to actually do this when moving from T-Mobile onto EE. It’s possible to submit the T-Mobile PAC Code directly to EE to move your number. For more information, take a look at the comments on this page: many of them are from other readers who’ve made the same move. By the way, don’t forget you’ll need to pay an early termination fee when ending your current contract.

  • Hello Ken, I have a t mobile monthly sim only contract but want to start a new phone contact with a third party through EE as it’s cheaper than upgrading through t mobile. I have got a PAC code, can I transfer my number to the new contract
    Thank you

    • Hi Angela,
      Thanks for your comment. It certainly shouldn’t be a problem moving your phone number from T-Mobile to EE. I recommend having a look at the comments on this page for some experiences from other users transferring their phone number from T-Mobile to EE.

  • I have just come out of a 24 month contract with T-Mobile
    I asked for a PAC CODE but was put through to the loyalty team who offered a 4G SIM Only deal. The SIM card had a temporary number.
    I called 150 and told them my T-Mobile number had not migrated across as promised.
    They tried to do it but couldn’t – they said there was a problem with the SIM and that I needed to get a replacement.
    I got the replacement SIM card and now my phone says no service.
    I have contacted customers services who can’t explain why the old number has not migrated and who have escalated the issue upwards.
    I still haven’t heard anything back and haven’t been given a time frame for the resolution of the problem.
    This really is very poor considering EE AND T-MOBILE are part of the same group of companies…
    I’m really unhappy and would like to leave EE due to their incompetence in not being able to migrate my number from T-Mobile to EE and upgrade my plan

  • Can anyone help?

    I’ve recently come out of a 24 month contract with T-mobile which I then changed to PAYG. I soon realised that my monthly usage (although relatively low) wasn’t cost effective as PAYG. I currently have just over £1.00 credit on this phone – an unlocked Samsung Galaxy S2.

    I started looking at monthly deals and just over a week ago, signed up or another 24 month contract with EE. Apparently I cannot transfer my T-mobile number to EE even though they are on the same network.

    It was suggested that I get a third party SIM, e.g. Vodafone (which is not part of the EE network) and transfer the old T-mobile number to Vodafone, and one this is done requested a PAC code from Vodafone to transfer the ‘new’ (but original T-mobile number) to EE. Hopefully does this make sense? What happens to my old T-mobile SIM? Can I request a new number for that or is it just ‘tough’ with any remaining credit being forfeited?

    Can anyone come up with a better scenario?

    Regards.

    • Hi Pat,
      As a T-Mobile customer moving to EE, the recommended thing to do is to upgrade directly to EE. In your case, you’ve signed up as a new customer on EE which means using a PAC Code to move your number over.
      Have you tried obtaining the PAC from T-Mobile and submitting it to EE via this online form? After doing this, the number transfer should be processed just like any other. It might be easier to do this than going via Customer Services (customer services may insist it can’t be done as they’d prefer you to upgrade rather than to sign up as a new customer).

      • Thanks very much Ken for your prompt response – I sure wish that you I got the same response from ALL of the customer services people I have spoken to over the past few days. I have wasted so much time trying to get this resolved. The only reason I did not ‘upgrade’ from T-Mobile to EE is that the same deal cost over £2.00 per month more (for 24 months). So…… I’ve completed the form (many thanks for the link) and I now wait to see what happens tomorrow. Hopefully by 17:30, my ‘old’ telephone number will be on my ‘new’ phone and I will no longer keep receiving calls for a Ms Donoghue!

        Now all I need to do is try to ensure that I get all my contacts exported safely.

        PS. Why to service centres which are so very obviously based in India insist that there staff adopt ‘English’ names, i.e. I’ve recently spoken with Sharon, Peter and Mark – who speak very poor English – very fast! (rant over).

    • Yay – filled in the form as suggested. A few hours later got a text message from EE stating that there was a problem and to call them on 150. Ages later (as they were so busy), I managed to get through to a customer services lady who took ages to check my T-Mobile account and my EE account and then said that she could do the transfer for me. So before thanking her and saying goodbye, I check that the tranfer will take place before 17:30 today (Wednesday) – ‘yes’ she says.

      Woke up this morning to discover that my T-mobile SIM no longer works (only lost £0.89p) and very pleased to say that my new ‘EE’ phone now has my ‘old’ mobile number. Woo-hoo – only took 12 days and I would have been none the wiser had I not stumbled upon your web site so THANK YOU very much!

      • Woo hoo – congratulations Pat and glad to know the phone number transferred successfully! Hope you enjoy using your phone on EE and thanks again for keeping us updated about how the transfer went!

  • I have recently signed-up for a contract for an iPhone 5S at Phones4U. I wanted to retain my existing T-Mobile PAYG number and the best coverage option was offered by EE 4G.

    However, the P4U salesperson told me I could not transfer a T-M number directly to EE, because they are “effectively the same provider” and that if I wanted to retain my number, I would either have to transfer it first to a ‘third party’ SIM and then transfer it again to EE, or choose another (3G) provider.

    In the event I chose another provider, although I have not yet effected the transfer. But, having now researched this on your website, the advice I was given seems somewhat dubious.

    Can you clarify the position, please?

    • Hi Tony,
      Thanks for your comment. As you mentioned, T-Mobile and EE are essentially the same company (T-Mobile is a 3G-only brand whereas EE also provides 4G coverage). As part of the push towards 4G, EE has tried to encourage T-Mobile customers to upgrade to 4GEE. This is normally done as an upgrade within the network (there’s no need to use a PAC Code). In your situation, you were looking to sign up as a new customer on 4GEE and to port your old number from T-Mobile. Though I haven’t tried it, I believe a PAC Code would also do the job in this situation (e.g. you can still use a PAC code though it’s not totally necessary). A PAC Code is still required to transfer your number from Orange to T-Mobile.
      Hope this helps,
      Ken

    Hi,

    Just switching from T mobile to EE, and have simply turned off my old phone, and left on my new one, as advised by EE.
    The new phone does have a number in it, ( although not my number ) and I can make calls, although no mobile network.
    Is this normal, and will my existing number transfer automatically within a few hours or so ?
    Any help appreciated !

    • Hi Nigel,

      Thanks for your comment. It’s really odd that this has happened: especially as you’re upgrading from T-Mobile to EE (technically, both are now the same network). If the problem doesn’t resolve itself within a couple of hours, I’d recommend calling EE customer services on 150. Do keep us updated on how you get on!

      Ken
