giffgaff SIM Only for iPhone
giffgaff is a Pay As you Go network with the added benefit of bolt-ons or “Goodybags” that add extra features for 30 days at a time.
What really sets giffgaff apart is the way they do support. giffgaff doesn’t have call centres or first line support staff – other members offer support in exchange for “Payback”.
giffgaff is not “one of the little guys”. It is heavily funded by O2 and Telefonica and definitely is not a startup. It does have its own personality though, and does things differently to most networks.
