    Hi, I want to leave Vodaphone & had asked them for a pac code, they sent me an email with a 20 digit code. As I have never dealt with this situation before I assumed this was the code, I joined ID & set up my app I D account. I went into my ID account & set about transferring my original number over to ID.
    When I tried to input the code ID said there was a problem. I have now googled the problem & found out a pac code is only 9 digits ! What was the 20 digit number Vodaphone sent me & can I still get my original number transferred to my new phone ?
    I’m grateful for any advice.
    Regards
    Steve.

      Hi Steve,
      Thanks for your comment. That’s a very good question: I actually have no idea what the 20-digit number is (most frequently, the PAC Code is confused for a PUK code but that would only be 8 digits long rather than 20 digits long). My guess is it’s probably an account number or something along those lines, but you’ll need to check directly with the team at Vodafone.
      To get your phone number transferred to iD Mobile, you’ll need to contact Vodafone customer support once again to request a new PAC Code. This should be nine-digits long with three letters followed by six numbers (e.g. VOD 123 456).
      Hope this helps,
      Ken

        Hi, never got to the bottom of this. I have had to cancel my contract with Vodafone & buy a new phone that was unlocked to any network. Vodaphone were a nightmare to deal with , never ever deal with them again !.

    Hi Ken
    Hope you can help me. I took out 2 contracts with Carphone Warehouse last weekend upgrading to a new phone with ID. When I was charging the mobiles I noticed that my boyfriend’s mobile had already been used. There were emails on from last July and data had already been used. I went back to CW had told the man who had sorted the contracts what he’d done and the reply I got was he didn’t realise it was a shop phone he’d given me and said I had to get in touch with ID to sort the data out. He gave me a new mobile but with the same sim card. They weren’t helpful at all. I rang ID the next day and told the lady what had happened and she said they should have given me a brand new phone and sim card. She was very apologetic and said if I go back to CW and tell them to ring ID they will change my contact to a better deal at the same price. During the week I got the pac code and transferred the old numbers onto the new mobiles. I went into CW today and told them I’d spoken to someone at ID and they told me they had to ring ID to get the deal changed over. While I was waiting they cancelled both contracts before they rang ID and took the phones off me. I asked if they were going to ring them and I think it was the manager , rang the number but gave me the phone as they don’t speak to ID about upgrades! So I had to sort new contracts out but because our old numbers had already been transferred we had to have new numbers! If they hadn’t cancelled the contracts beforehand and explained what had to be done to keep the numbers we wouldn’t have lost them. I’ve made a complaint against the CW store with ID and CW. The regional manager should be getting in touch with me next week. Do you know if there is any way of keeping the numbers without changing networks and cancelling the contracts again? If I have to do that we have to send the mobiles back to ID and will be without a phone again. I have never come across customer service as bad as this before. Hope you can help. Thank you.

      Hi Lisa,
      Sorry to hear about the problems you experienced on iD Mobile. Unfortunately, I’m not able to help with the complaint as I don’t know all of the details of the situation. However, with regards to keeping the phone number, this is something you’ll need to ask iD Mobile to do for you. Sorry: I know this probably isn’t very helpful, but the only other alternative would be asking for a PAC Code and moving your phone number over to another network.

    Yeah I’m also with ID mobile wanting to change to a better tariff to which they are not capable of doing, its just crazy you have to leave to come back to change your plan………

    All in all the network is fine but when it comes to changing your plan good luck!! So frustrating.

    Raised a complaint and you will simply get no where, as they just simply repeat they do not have the facility to change plan.

    Hi Ken,

    I was wondering if you could shed some light on my situation…

    I have been with iD mobile for a few months on a sim only contract when I noticed they were offering a much better deal for the same money so I wanted to switch within the same network. I was told that they don’t have the abilities to do this yet as they are relatively new, so would have to end my contract, port my number out to a different network, and then port it back in to a new contract.

    So I cancelled my initial iD contract, with 30 days notice and got my PAC code which I used to port my number out to 3 mobile on a pay-as-you-go sim card. Once this had gone through, I then requested a PAC code from 3 mobile to transfer my number back to iD.

    I set up a new, much better tarrif contract with iD mobile and attempted to use the PAC code 3 mobile had given me to transfer my old number from 3 to iD. This was done via their website, but I immediately got an error message. I then called up iD mobile to query the error message and they suggested it was because it was a Friday and it would go through after the weekend. Needless to say, it never transferred, so I called them again, this time they suggested it may be a problem with the PAC code, and I should contact my old provider (3 mobile) to check the PAC code was correct. So next I contact 3 mobile, who said they couldn’t provide a new PAC code as the code had already been used and the account was closed. I relayed this message back to iD mobile and their next suggestion was that my number had somehow been ported back to my old account, which is now closed, and that there is not much chance of me getting my number back. Their IT department are now looking into the matter, but may take up to a week to get back to me with any further detail.

    I’m confused as to how this can have happened, surely if I ported my number out of iD to 3mobile then the old account would have been closed – how could someone then port the number back to a closed account?

    Any help/advise would be very much appreciated!

      Hi Laura,
      Thanks for your comment. Sorry, this isn’t something I’m able to help with, as it’s an account-specific question relating to your port. I’m not really sure how the systems are set up at iD Mobile and how your number might have accidentally been ported in to the wrong account. So sorry – though please do keep me updated as I’m sure other readers of this website could also find this info useful.

      Hello Laura,
      Just read about you’re issue with ID mobile.
      I am in the same situation, they have been messing me around for almost 3 weeks. They keep saying they are trying to retrieve my number.
      Did you get your number back?
      I’m considering taking the matter to court because I need that number.
      I’ve had it for 20years.
      Please let me know the outcome of your case.

      Cheers Kae.

      1. Laura replied:

        Hi Kae,

        Yes! Good news…I finally got it back after about a month. Was a very long process of not much information and calling the customer service team daily but got there in the end. I also found contacting them on Twitter got a better response.

    Hi Ken
    ID mobile seems to have lost my number during porting in process !!!! 5th November !!!
    Nightmare situation! I have had my number over 10 years and changed networks several times with no problems transferring my number. The PAC code from ee was not accepted on ID website when I first tried it in October so ee sent me another PAC code a couple of weeks later and I had same problem with it not being accepted. I therefore decided to wait until end of November to try again (as I was in contract with ee until 4th December) However my ee network stopped working on 4th November and ee told me that the new provider had in ported my number. I called ID 7777 on 6th November to confirm when number will be up and running and they said they would send a ‘ticket’ to tech dept and contact me to confirm.
    I have called customer services 7777 on numerous occasions and been into carphone warehouse and also completed 2 complaint forms on their web site. NOTHING has happened I still have not got my number back and I have been promised that I will get a call from management but they have not been in touch.
    This is big problem for me as so many people in business and personal contacts have my old number. PLEASE ADVISE

    Hi,

    In respect of your piece above on upgrading or changing an ID Mobile plan, I’ve just called them to do just this and the only option they provided was to cancel my contract and apply for a new sim on the plan I want to change and port the number.

    Bonkers.

    Hi Ken, I wonder if you could tell me where I stand regarding the problem I’m having with porting my number over to iD.

    I got my pac code from O2 and used id’s online porting facility on July 1st to transfer on July 2nd, my O2 sim went dead on the 2nd but iD where having network problems so I couldn’t check for 4 days, when I find it didn’t go through?

    I have contacted iD CS numerous times to resolve this, but they say next day, three to five days, I am getting nowhere with them, any ideas?

    Kind regards,

    Gerry.

      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.
      Best of luck,
      Ken

        Hi Ken, Thanks for your prompt reply and links.

        I am waiting on them getting back to me by this evening.

        But if they have lost my number ( I don’t understand why it hasn’t gone over ? ), do I have any legal entitlement?

        Kind regards,

        Gerry.

          Ken replied:

          Hi Gerry,
          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! 🙁

    iDmobile mistakingly cancelled my contract then lost my mobile and can’t re-enable it to issue me a PAC for my business mobile number…..

    I ported my number from Vodafone to iDmobile, everything worked fine until the line disconnected one evening. I rang iDmobile and visited carphonewarehouse who both confirmed that between them they’d accidentally cancelled my contract, lost my number, and now I’m stuck without a business mobile. Vodafone confirm the number was ported across to the 3 network, and also advise that re-enabling the number and then generating the PAC is something that can be done normally in their experience – yet iDmobile seem unwilling to even discuss it and carephonewarehouse aren’t making much progress.

      Hi Don,
      Sorry to hear about the problems moving your phone number from Vodafone to iD Mobile. I recommend making an official complaint to iD Mobile as quickly as you can – they should assign you a person to deal with the case. Unfortunately, there’s isn’t any more help I’m able to provide but I hope the problem can be resolved quickly and in your favour.
      Please do keep us updated if you hear any more from iD Mobile.
