Transfer my number to T-Mobile
How to switch to T-Mobile and keep my number?
First get your T-Mobile package and activate your new SIM card.
Once you have done that, get the following information ready to follow the step-by-step instructions:
- Your old mobile phone number that you want to keep.
- The PAC code (Porting Authorization Code) 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 T-Mobile SIM card activation.
- You may also need the new T-Mobile SIM card serial number found on the back as an additional security check.
Call T-Mobile on 150 from your TMobile number, or on 0207 362 0200 from another phone and give them your PAC code from your previous network provider.
T Mobile will then confirm with you the switch date for when your original number will be automatically ported over to your new T-Mobile SIM.
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 T-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.
