Instructions to switch from iD Mobile & take your mobile number with you :

Contact iD Mobile customer services by calling 7777 free from your iD Mobile phone or 0333 003 7777 from any other telephone to request your PAC code. Make sure you ask for the PAC before the end of any contract agreement.

  • iD Mobile will provide your Port Authorisation Code (PAC number) either over the telephone, by SMS text message or via email.
  • A PAC code is valid for 30 days. If you don't use it within thirty days it will expire and you will need to request a new one.
  • Your iD Mobile account will remain active until your number has been ported over to the new network. After the transfer is complete, your iD Mobile account will be automatically closed.
  • iD Mobile must issue you with a PAC number within 2 working days of your request, or a reason for why it cannot be issued, in accordance with Ofcom's "General Conditions of Entitlement". http://ofcom.org.uk

Once you have received your Port Authorization Code from iD Mobile, look for the best offer that is suited to you. Many of the best mobile phone deals are available exclusively online, directly from the network providers listed here.

Finally, provide your PAC code to your new mobile network operator who will then be able to port your existing phone number from iD Mobile. They will tell you what day the transfer is due to take place (usually within 48 hours).

Important: Do NOT cancel your contract before switching, otherwise you might not be able to port over your number. Once you provide your new network provider with your PAC code, your old account will automatically be cancelled when the number is migrated over.

Note: Credit on a PAYG (Pay-As-You-Go / Pre-Pay) account cannot be transferred and any remaining credit will be lost after the switch over.
