Switch from BT to 1pMobile and keep your number using a PAC code
Ofcom’s policies have made it extremely quick and easy to switch and transfer your BT number to 1pMobile.
It’s completely free to transfer your number - you simply need to request a PAC code from BT by sending a text message, which takes no more than 2 minutes to arrive. Once you’ve handed the PAC code to 1pMobile, the switching process will take no more than 1 to 2 working days to complete.
If you want to join 1pMobile and get a brand new phone number, without keeping your existing BT number, the process is almost identical - the only difference being you will need to request a STAC code instead of a PAC code.
Joining 1pMobile from BT
Joining 1pMobile and transferring your number from BT is a very easy process, and should take no more than 1 to 2 working days.
You simply need to request a free PAC code from your BT number, and hand it to 1pMobile.
You can hand your PAC code to 1pMobile at the time of ordering a new 1pMobile phone or 1pMobile SIM, or you can do this after you’ve received your order. When you choose to do this is up to you - it doesn’t make a difference.
After you’ve handed your PAC code to 1pMobile, your number will be transferred to 1pMobile within 1 to 2 working days, and your account with BT will automatically be closed.
1. Request a PAC code from BT
Requesting a PAC code from BT is quick and free. The easiest way to do this is via text:
- Text: From your BT number, text PAC to 65075 for free. You will receive a reply within 2 minutes, containing your PAC code
- Online: Login to your BT Mobile account and request a PAC code
- Phone: Call 150 from your BT Mobile number or 0330 1234 150 from any other number.
- Monday to Friday: 8am - 9pm
- Weekends and bank holidays: 8am - 8pm
You will have 30 days to hand your PAC code to 1pMobile, after which it will expire and you will need to request another one from BT.
Note: If you wish to switch to 1pMobile, but you want a brand new number without keeping your BT number, you need to request a STAC code rather than a PAC code from BT. You can do this by texting STAC to 75075 instead.
