Transferring your number is easy

Just follow these simple steps

First up, if you pay your bill monthly, check whether you're still under contract with your current service provider. It's a good idea to check this out, because cancellation charges may apply.
If you haven't done so already, buy a new phone or get a free SIM from us.
Get in touch with your old service provider and ask for a PAC code.
Call us on 08454 123123 and give us your PAC code. Or call Customer Services on 150 from your handset.

Hints and tips

Make sure you use up all your credit on your old network
Don't forget to copy information from your existing SIM over to your new one. You can always bring both SIMs into one of our stores and we'll transfer the data for you
Make sure the phone you're transferring your number to is in the UK on the day that your transfer takes place
Using your temporary number on My T-Mobile - once the transfer is done, you'll need to log in and select the number you brought over as the primary number on your account
Your first bill will show line rental charges and allowances for both your temporary number and the number you brought over

What is my PAC for?
PAC stands for Porting Authorisation Code, and you need it in order to move numbers from one network to another. Basically, it gives you permission to leave your network and allows us to transfer the number on to our network.

Once a PAC is issued, it's only valid for 30 days. If it expires, your mobile number stays with the network it's already on.

Can I transfer my number from or to a pay as you go plan?
Absolutely! As long as the number is still on a network, it's easy to bring it over to us.

Can I cancel my request to transfer my number?
If you've given us your PAC and we've entered it into our system, the transfer will take place on the specified date.

How long will the transfer take?
The process takes one working day.

Can I transfer more than one number to your network?
Of course. All you need to do is give us the numbers and their corresponding PAC codes. We'll take care of the rest.
