giffgaff offers & cashback

1 2 3 4 5

Hi, we're giffgaff, a pay as you go, SIM-only mobile network with a difference. We're run by our members for a start. Our members get rewarded for running parts of our business like answering questions in the giffgaff community or recruiting new members. We're online only, with no crowded shops or frustrating call centres, meaning we keep our costs low and pass the savings back to our members.

Great value goodybags and gigabags

Order your free SIM, and when it arrives you can choose from our selection of great value goodybags, giving you a mix of UK minutes, texts and data that lasts a month. You can set this to recur automatically, or change it each month depending on your usage.

You can also pop a giffgaff SIM in your tablet, using one of our data only gigabags.
