SIM and number

Keep your number when you join giffgaff

To transfer your phone number to giffgaff, you first need to ask your old mobile provider for a Porting Authorisation Code (PAC). You can then use the transfer form to submit your PAC and choose a date for the transfer. If your number hasn't been transferred the day after the scheduled date, you can contact an agent about it. We can only transfer UK numbers to giffgaff.

What happens if there's a delay when switching to giffgaff?

If you’re unhappy with how we have conducted the switching process and believe that you have suffered a loss of service as a direct result of our delay, please contact an agent and once we’ve investigated the port in/out and verified your loss of service, we’ll ensure you receive reasonable compensation as soon as we reasonably can. For issues with porting out, payment will be made back to your saved card. For issues with porting in, we will apply credit to your account.
