giffgaff deals and contracts

A pioneer in flexible 1 month rolling SIMs, giffgaff was one of the first UK networks to capitalise on the smartphone boom. Founded as a subsidiary of O2 in 2009, giffgaff became renowned for their cheap SIM only deals, particularly among young adults at the time.

Despite still offering decent value for money, giffgaff has struggled to compete with newer MVNOs in recent years, and often seems neglected at times, particularly following the Virgin Media and O2 merger.

While you can probably get better value from other MVNOs, giffgaff is still a reliable and consistent provider backed by O2. In addition, their phone plans often have some hidden gems, with 0% interest financing for many of the latest devices.
