Fuse vs Three

Why Fuse
What you get with Fuse that you don't with Three.
Multi-network coverage
Three has strong 5G in cities but limited rural coverage. Fuse gives you Three plus EE, Vodafone and O2 — four networks combined for 99%+ UK coverage.
More roaming destinations
Three's Go Roam covers 71 countries. Fuse covers 130+ countries worldwide — nearly twice as many destinations.
Same 5G + three more networks
You still get Three's 5G through Fuse, plus EE, Vodafone and O2. 5G where available on any network, with reliable 4G fallback from four providers instead of one.
