Of course. All you need is a Porting Authorisation Code (PAC) from your old mobile provider.
A PAC is a 9-character code which allows us to transfer your number from your old provider to BT. Your PAC is valid for 30 days from when it's issued.
You can give us your PAC when you’re ordering your phone or SIM. Or you can log into www.bt.com/keepyournumber and enter your PAC code there. If you don’t have one already, you’ll need to create a BT ID >
Once we have your PAC, the transfer usually takes 24 hours. We'll keep in touch with you to let you know what's happening.
If you ask us to transfer your number before 3pm on a week day, we'll move it over by the next working day. We won’t move numbers over a weekend or a bank holiday, or the last working day before a bank holiday.
Watch the video below to find out more.
What if I change my mind?
Once you've asked to move your number, we can only cancel it if you contact us before 3pm on the working day before your number is due to move. Most transfers only take 24 hours, so this means you’ll need to cancel before 3pm on the same day you asked us to move it.
If it's after this time, you'll need to wait until it's moved and then arrange for it to be moved back. If you need to get in touch, call 150 from your mobile or 0800 800 150 from another phone.
Will everything keep working if I move my number?
Both your old and new numbers will work until the move completes.
So both SIMs will work in your phone, but calls to the number that's moving will go to your old provider's SIM until the move to BT Mobile is finished.
What happens on the day?
We'll text you when it's done. Once we've texted, pop the BT Mobile SIM in your phone (if you haven't done it already). Any calls to your number will be on the BT Mobile service.
The service with your old provider will finish later in the day.
Any problems on the day, try switching your phone off, then back on again. If you can't get things working, please get in touch.
