- BT Mobile will provide your PAC code (Porting Authorisation Code) either by SMS text message, via email, or over the phone if you contact them.
- A PAC number 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 BT Mobile account will remain active until your number has been ported over to your new BT Mobile network. After the transfer is complete, your old BT Mobile account will be automatically closed.

Got your BT Mobile PAC code?
Provide your PAC code from BT Mobile to BT Mobile who will then be able to port your existing BT Mobile number. They will tell you what day the transfer is due to take place (usually within 48 hours).
Important: Do NOT cancel your SIM only or mobile contract before switching, otherwise you may lose your current phone number and be unable to port it over. Once you give BT Mobile your BT Mobile PAC code, your old BT Mobile billing account will be closed automatically when your mobile phone 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 by SMS text message before porting your number.

Call BT by dialing 150 from your BT Mobile or 0800 800 150 from another phone or +44 179 359 6931 from abroad. Have your BT phone or account number ready, along with your Porting Authorisation Code (PAC), and let them know that you'd like to transfer your old mobile phone number across to them.
Note: You may lose network service for a short period on the day of transfer. If this happens, turn your phone off and on occasionally, until you see the BT Mobile signal on your mobile phone screen. This will indicate that the transfer is complete, and you can now use your old phone number in your new mobile network provider.
