Porting your mobile number from iD Mobile

Leaving iD Mobile

How to switch from iD Mobile & transfer your mobile number

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.

If you wish to use the 'text-to-switch' service, simply SMS text PAC to 65075 free from your iD Mobile SIM to get your PAC code by text and begin the porting process.

  • iD Mobile will provide your Porting Authorisation Code (PAC) either over the phone, 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.

Many of the top mobile phone deals are available exclusively online, directly from the network providers listed here. So once you have received your Port Authorization Code from iD Mobile, get the best offer suited to you.

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 may lose your existing phone number and be unable to port it over. Once you provide your new network provider with your PAC code, your old account will be clsoed automatically once the number is successfully ported over.

Note: Credit on Pre-Pay / PAYG (Pay-As-You-Go) accounts cannot be transferred over and so any remaining credit balance will be lost after the switch is complete. If you have any credit left, one good option is to donate it to a charity before porting your number.
