The problem
You're locked to one network. And it's costing you.
17%
of the UK has no reliable 4G from any single network
1 in 3
people experience regular signal dead spots
4 networks
cover different areas — none covers them all
One network can't cover everywhere. EE drops where Vodafone is strong. Three fails where O2 holds steady.
You're paying for one coverage map — and hoping it's enough.
The solution
What if your phone could use every network?
Fuse connects your phone to all four UK networks through one eSIM. Your phone picks the strongest signal automatically — nothing to configure.
99.8% UK population coverage. Fewer dead spots. Better signal — everywhere.

Real stories
Built for people who can't afford to lose signal.
Signal problems aren't just annoying — they cost people money, waste their time, and put them at risk.
The delivery driver
James — Norfolk
James drives between postcodes across Norfolk six days a week. His route takes him through villages, country lanes, and industrial estates — places where signal is unpredictable at best.
“With my old SIM, I'd lose signal in half the villages I deliver to. Couldn't load the route, couldn't confirm the drop-off, couldn't contact the depot. I'd sit in a layby for ten minutes waiting for a bar of signal. With Fuse, my phone just switches to whatever network works. I haven't lost signal once in three weeks. That's three weeks of every delivery confirmed on time.”
Why multi-network
Still stuck on one network?
Every UK network has gaps. The difference is whether you're stuck with them or free to switch. Fuse connects to all four major networks, so your phone always finds the strongest signal.
