Why choose Fuse over giffgaff?
giffgaff has built a loyal community, but Fuse gives you access to every UK network — not just O2.
Multi-network advantage
giffgaff runs exclusively on O2, which means your coverage depends entirely on one network. Fuse connects to all four UK networks — EE, Three, Vodafone, and O2 — so your device automatically selects the strongest signal wherever you are.
eSIM technology
giffgaff still relies on physical SIM cards sent by post. Fuse uses eSIM technology, so you can activate your plan instantly — no waiting for delivery, no fiddling with SIM trays. Just scan and go.
Global roaming
Fuse gives you data in 130+ countries worldwide. giffgaff limits roaming to the EU and a handful of selected destinations, which can leave you without affordable data on trips further afield.
Better value
Fuse plans start from just £5.99 per month — lower than giffgaff's £10 starting price — and you get access to four networks instead of one. More coverage, more flexibility, less cost.
