How to Switch to giffgaff
Joining giffgaff with your existing number is simple and can be done entirely online. Start by requesting your PAC code from your current network — text PAC to 65075 from your current handset. Once you have your PAC, order a free giffgaff SIM card from their website, or pick one up from a supermarket or high street store. When your SIM arrives, activate it on the giffgaff website and choose a goodybag (their term for a monthly plan). During activation, enter your PAC code to transfer your existing number. The number port usually completes within one working day. Because giffgaff has no contracts, you are free to change or cancel your goodybag at any time without penalty.
