Once Your New Phone Arrives...

Once you're happy to continue with the transfer, your PAC Code should be entered on iD Mobile's online form. Alternatively, you can give the PAC Code to iD Mobile by calling 7777 on your iD Mobile handset. You can also call 0333 003 7777 from any other phone.

Providing your PAC Code to iD Mobile

If your PAC Code is provided before 6.00pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). For PAC Codes submitted after the 6.00pm cut-off, you'll need to wait one extra working day for your number to be transferred.

  • I want to transfer to ID from EE. I have sent a disconnection request to EE, so my contract will end once this final month is up. I have obtained the PAC code from EE, and I was told I have to use this within 28 days otherwise my contact with them will automatically restart and I’ll have to wait another month. However, I am currently abroad – so I want to buy an ID sim (a sim only monthly deal), use the PAC code to transfer my number to the ID sim, and only later put the sim in my phone once I return home. Is this possible, or would I have to put the new ID sim in my phone first to activate it or something, before using the PAC code?

    B transferred a phone number from EE to iD Mobile.

    • Hi B,
      Thanks for your comment. You’re right in saying that a PAC Code is only valid for 30 days (which means you’ll need to give it to your new mobile network several days before this to ensure your phone number is moved over during this time). If it expires, you’ll need to request a new PAC Code from EE.
      With regards to your iD Mobile SIM card, it should be possible to transfer the phone number to it providing it has been activated. However, I don’t know enough about the specifics of how iD Mobile works (e.g. whether the SIM cards are automatically activated, or whether it depends on you putting the SIM card in your phone first). This is probably something best answered by iD Mobile Customer Services!

    Melv transferred a phone number from iD Mobile to Virgin Mobile.

    • Hi Melv,
      Thanks for your comment. Is this simply a matter of transferring your phone number from iD Mobile to Virgin? If so, there shouldn’t be a problem doing this regardless of how long the existing contract on Virgin Mobile has been held.
      Hope this helps,
      Ken

    alan transferred a phone number from EE to iD Mobile.

    • Hi Alan,
      Many thanks for your comment. Is this problem now resolved? Sometimes, you may receive your confirmation message before the switch is complete, but typically this will be resolved by end of day (so at least by 6pm).
      Ken
