How multi-network coverage works
Traditional mobile providers lock you to a single network. If that network has a weak signal in your area, you're stuck with poor coverage — even if another network has a strong signal right next door.
Fuse works differently. Our eSIM carries profiles for all four major UK networks: EE, Three, Vodafone, and O2. Your phone continuously monitors signal strength and automatically connects to whichever network offers the best service at your location.
This happens seamlessly in the background. You don't need to do anything — no manual switching, no settings to change. Whether you're commuting through central London, working from a rural village, or travelling between cities, your phone always picks the strongest available signal.
The result is coverage that no single network can match. By combining four networks into one eSIM, Fuse delivers 99%+ population coverage across the UK — fewer dead spots, more reliable connections, and better signal wherever you go.
