Transferring your number
Way back in the foggy mists of time the giffgaff SIM was a little less flexible than it is today and didn’t come as a three-in-one package. This made number transfers trickier. Of course, there isn’t a problem that our members can’t solve. They suggested members should be able to swap SIMs, ie, transfer your number from one SIM to a shiny new one and bring any existing goodybags or top-up along for the ride as well. And thus SIM Swap was born.
