Your PAC

To transfer your number, you'll need to ask your old network for a PAC (Porting Authorisation Code). You can get your PAC by texting 'PAC' to 65075 from the number you want to keep - you should get it in a minute or two. Alternatively, you can contact your old network to get your PAC.

A PAC is normally nine characters long, in the format 'ABC123456'.
