    I have recently transferred from Tesco to Talktalk mobile (last Monday) and for 2days I could make phone calls but not receive them. Dialing my number from my landline gave varying results from “You have dialed an incorrect number” to 2 ring tones then disconnected tone then “this number is not receiving calls at the moment”.
    Due to 2days of frustration I demanded the PAC code back and Transferred back to Tesco but the problem remained even with Tesco.
    Now a further 2 days without incoming calls (except from a friend with a Tesco SIM) I am again totaly frustrated.
    I have complained bitterly to tesco but still waiting. can you make any suggestions
    Regard

      Hi there,
      I’d recommend calling Tesco Mobile Customer Services on 4455 (0345 301 4455 if you’re calling from another phone). They should be able to arrange for this for you.
      Hope this helps,

    I am with TMobile/ EE on a PAYG
    I wanted to change to Tesco mobile. There is about £80 credit in my account will this money come with me when I get my pac code and change. I had requestd my money back but got refused thank you

      Hi Noeleen,
      Thanks for your comment. Unfortunately, it isn’t possible to transfer your Pay As You Go credit from one network to another, so you’ll need to use up the £80 of credit before you leave T-Mobile and join Tesco Mobile. If it’s not easy to use up the credit, you could possibly consider using the credit to pay for applications or music. Alternatively, you can choose to donate your credit to charity.
      Hope this helps,
      Ken

    I transferred from 3 to Tesco, got pac code on a Saturday 24 Sept and gave Tesco was told transfer would be done by Tuesday 27th. The number did show that it’s on Tesco when I checked my account and there’s Tesco signal on my handset. Unfortunately am not able to make or receive any calls or msgs on the number and now it’s 1st Nov nothing still. I did contact customer care Tesco they said they’ve made an escalation to three because they’ve not fully transferred all my files. How long does it take for them to get a response from three? It’s so frustrating.

    Is there such a thing as secondary pac numbers?
    I’m in the process of moving from Tesco mobile to Vodafone, I’ve been given a pac number by Tesco but Vodafone claim that they have given me a secondary number instead of a primary.
    Could this be true?

      Hi Neil,
      Thanks for your comment. I’ve never heard of a “secondary PAC number” – I’m also unable to find any reference for this in the mobile number portability manual. Does your PAC Code match the expected nine-digit format (e.g. ABC 123 456)? If not, it’s possible you’ve been given a PUK2 (used to gain access to your SIM card if you enter the PIN number incorrectly three times).

      Hi Alan,
      Thanks for your comment. Unfortunately, I’m not able to answer any specific requests pertaining to your account. It sounds to me as if your number transfer hasn’t been processed correctly (i.e. they probably haven’t entered your details into the system). You should contact Talkmobile Customer Services on 5888 to check on the status of your phone number transfer.

    Hi Ken
    Thanks for your excellent description of the old number to new phone process.
    I have just completed the same, from Vodafone to Tesco with no problem.
    However the number displayed in my new phone (moto G) status is still the temporary number allocated by Tesco. Will this update automatically, can I update it or will the phone always display the original number?

      Ken replied:

      Hi Paul,
      Thanks for your comment. Could you kindly elaborate on which feature of your new smartphone is showing the old number? If it’s an instant messaging app (e.g. WhatsApp), you’ll need to re-register the app under the new phone number. If it’s an outgoing call still showing the old number, this would be a problem to discuss with Tesco customer support (call 4455 using your Tesco handset and ask them to check the caller ID). Finally, if it’s a problem in the Android interface (e.g. the wrong number showing on the About screen) you can normally resolve this by restarting your handset.
      Hope this helps,

    Hello, I have just recently gone from pay as you go on T-Mobile to a Contract with Tesco mobile. A PAC code was issued to me and I gave this to Tesco mobile. I have only had the phone since 6 September and apparently my old number from T-Mobile was ported on 9 September to my new phone. I have recently been advised by people that they cannot reach me on my new mobile from a landline. When rung from a landline the signal received by them is a dead one. I can receive calls on my new phone from other mobiles. I am having a very frustrating and stressful time with Tesco Mobile in getting this matter resolved. All manner of things have been tried and nothing works. Do you please have any ideas. Hope this makes sense.

    Regards

      I am having a very similar experience I transferd my number from t mobile to giff gaff in September all was fine for the first 24 hours then I was unable to receive any calls from mobiles or landlines except from my daughter who is on O2, again just a dead tone. I then got no help from giff gaff so asked for another pac number and took out a new contract with a new hand set from O2, the exact same problem has occurred and again only my daughter or O2 can call me but I cann receive any text from anyone. O2 have disconnected me twice now and put me back on but this has not resolved the problem which I believe originates from t Mobile but they do not want to help as I am no longer their customer. This is a business number so really need to keep it please help

    I am thinking of ordering my new phone today on Tesco mobile, but I can’t request my pac code from T- mobile until next week without being charged as I still have over 30 days left on contract. Is it possible to change my number over to my new phone once I have it? Or do I have to do it online before I receive the new phone?

      Ken replied:

      Hi Danni,
      Thanks for your comment. You can request your PAC Code from T-Mobile at any time (the contract won’t actually be ended until your number transfers to Tesco Mobile). There’s never a charge for receiving your PAC Code. However, if you end your contract early (e.g. by giving the PAC Code to Tesco), you may be charged an early termination fee equivalent to 96% of the remaining cost of the contract.
      With regards to providing your PAC Code and transferring your number over to Tesco Mobile, you should always do this after receiving your new handset. It gives you an opportunity to test it out first (e.g. to make sure the handset works properly and that the coverage is OK in your home/office). So I would definitely recommend ordering the handset first – only after it arrives and you’re actually ready to move your phone number over, you can then fill out this form on TescoMobile.com.
      For more information, please see the step-by-step instructions on moving your phone number from T-Mobile to Tesco.
      Hope this helps!

    Dear Ken,

    I think you might be the most helpful person on the internet…

    I’ve recently moved from Orange to Tescomobile.

    On Thursday 19th June (it’s now tuesday 24th) I requested to have my old number transferred. They emailed me with:

    “Thanks for your recent request to keep your mobile number. We’re working on transferring it now” etc etc

    So all seemed good.

    But it’s now Tuesday and nothing’s happened (my phone is still working on a different number).

    Should I sit tight or get onto customer care?

    Thanks.

    Ed.

      Hi Ed,
      Thanks for the kind words 😉 If you provided the PAC Code to Tesco on Thursday, the number transfer should have completed sometime on Friday (otherwise on Monday if you missed the daily cut-off). As it’s now Tuesday and your number has still failed to transfer, I would definitely recommended getting in touch with Tesco Customer Services (you can do this by dialling 4455 from your Tesco handset). They should be able to give you an update on the transfer (it might be possible they forgot to action the transfer).
      Hope this helps,

    Hi Ken
    I have transferred my number using a PAC code from Vodafone to Tesco mobile. The number appeared to transfer successfully as I am receiving texts to my old number on my new phone, but when I send messages it is my temporary tesco mobile number that is appearing on the receiver’s phone. Will this disappear once my vodafone contract finally ends in 30 days?

      Hi Mairi,

      Thanks for your comment. It looks as if there’s a problem on Tesco Mobile’s side. They haven’t yet updated your Caller ID number which is why it’s showing your old temporary number. I recommend getting in touch with their Customer Services team: dial 4455 on your Tesco Mobile handset. Fingers crossed they should be able to fix the problem for you!

      Hi Janette,
      Changing your mobile network won’t affect the photos on your phone. If you’re upgrading to a new smartphone, you might need to copy your photos across. Take a look at my guides on transferring your data between Android devices. Alternatively, from iPhone to Android or from BlackBerry to Android.

    Hi I have received a PAC code from Tesco Mobile, but Vodafone says that it’s invalid. I’ve talked to each company several times. Tesco say they can’t generate a new PAC code until this one expires. I’ve triple-checked the number and the code, but now I’m at an impasse.

    What can I do?

      Hi Dave,

      I’m sorry to hear your problems about transferring a phone number. I’m not really sure what the solution is to this. As you mention, you can double-check the PAC Code making sure it’s in the right format (nine-digits long, in the format ABC 123 123). Also make sure that characters haven’t been mis-read (e.g. a 1 for an I or a 0 for an O). Aside from that, there’s no reason why your PAC code shouldn’t work. In order to generate the PAC, Tesco should have registered it on a central database that all of the mobile operators use. I’d ask them to double-check that this has been completed. In my view, the problem is more likely to have originated on Tesco’s side as they would be responsible for putting your request in the central database, etc. As long as the PAC was correctly given to Vodafone, there’s unlikely to be any problems on that side.

    Hi Ken
    my wife has a PAYG phone with virgin (uk) and would like to switch to a tesco sim only monthly contract. but her phone is locked and virgin said it would cost £15 to unlock. does this Pac code unlock the phone or do we need to pay vigin the money first.

      No, a PAC Code will not unlock your phone – it only allows you to move your number. Your unlocking code costs £15 and unlocks the phone, the PAC Code is free and allows you to transfer your phone number.

      Hope this helps!

    I wonder if you can help. I am transferring from 3 (really bad signal) to Tesco Mobile and my phone is going through the PAC process today from 8 til 4 pm. Once the number has transferred over to my new phone does that mean my contract with 3 has ended? Do I have to contact them to confirm? They are not a very good customer services to deal with so am a little worried.
