Giffgaff SIM only deals

Giffgaff operates on O2's network, so you get O2's coverage and 5G in supported areas while benefiting from Giffgaff's flexible, no-contract pricing.

It's worth checking O2 coverage at your home and work postcodes before joining to be sure the signal suits you.

Goodybags are rolling 30-day bundles with no commitment, while the 18-month plans fix your allowance and price for longer, often at a lower effective monthly cost.

Choose goodybags for flexibility, or an 18-month plan if you want certainty and a slightly cheaper rate over time.
