Cheapest Giffgaff SIM only deals

A goodybag is giffgaff's monthly bundle of data, minutes and texts that you buy upfront with no credit check and no long contract.

Each goodybag runs for 30 days and you simply choose a new one when it ends, so you can move up or down a plan as your usage changes without penalty.

giffgaff runs on the O2 network, giving you O2's 4G and 5G coverage across the UK on flexible 30-day plans.

The smaller goodybags are where the biggest savings are, and because there's no contract you can always switch to a cheaper bundle in a month if your needs drop.
