Porting your mobile number to BT Mobile

Joining BT Mobile

How to switch to BT Mobile and keep my number?

The first step is to select your BT Mobile deal and receive your new SIM card.

Once you have done that, ensure you have the following information ready:

  • Your original mobile phone number you want to keep.
  • The Porting Authorisation Code (PAC) from your previous network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new BT Mobile sim card.
  • You may also need the new SIM card number found on the back.

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 existing phone number in your new mobile network provider.
