Can't add phone number to new online account

I’ve had 4 numbers (for myself and various family members) for many years. They were all paid for by me and under my name.

I now just have 2 numbers with ID; my wife and daughter.

I’ve created a “new” online account successfully, but I can’t add either of their numbers. I’ve tried using name/DOB for me, my wife and my daughter, but it says “details not recognised” in all cases.  Previously I had a separate online logon for each phone number, which was a bit awkward but worked.

Sounds like I’m not alone. Please could you advise how to proceed

Regards,

Martin Wilkinson

    I'm also having the same issue as I am unable to add my number to my new online account. 

     

    I get the following message.:

    Sorry, your details do not match our records

    Please try again.

    Hey there ​@costapereira, sorry to hear that.

     

    Just to confirm, is this when trying to register the account for the first time, or when trying to add your plan to an already created account when logged in?

     

    Thanks,

    Tyler

    Hi ​@Dilz 

     

    Have you tried the following link to activate your replacement SIM card without having an app account?

    I cant add my number either, my number was transfered over to my ID sim today and my current number states it doesn't match their records and the number the sim came with states an error?

    Hi ​@Jomusiclover,

     

    We're sorry to hear you're having trouble adding your number.

     

    As your number was only transferred to your iD Mobile SIM today, it can take up to 24 hours for all of our systems to update following the port.

     

    We'd recommend waiting until tomorrow and then trying again. It may also help to sign in using an Incognito/Private browsing window if you're using a web browser, or close and reopen the iD Mobile app before trying again.

     

    If you're still unable to add the number after 24 hours, please contact our Customer Service team via Live Chat so they can investigate further.

     

    Regards,
