About Fuse
Fuse Mobile was born from a simple frustration: why do we accept dead spots? In a country with four major networks, no single one covers everywhere. We thought there had to be a better way.
So we built Fuse — a multi-network eSIM that connects to all four UK networks through a single digital SIM. Your phone automatically picks the strongest signal available, giving you better coverage wherever you go.
“Our mission is to give everyone in the UK the best possible mobile signal — no matter where they are.”
What we stand for
Transparency
No hidden fees, no locked contracts, no fine print. We believe you should know exactly what you're paying for.
Simplicity
Mobile connectivity shouldn't be complicated. One eSIM, four networks, simple pricing. That's it.
Sustainability
Every eSIM activation means one less plastic SIM card. We're working towards carbon negative operations because better signal shouldn't cost the planet.
Why “Fuse”?
Fuse means to join together. That's exactly what we do — we fuse all four UK mobile networks into a single eSIM. Instead of being locked to one network, your phone seamlessly switches between EE, Three, Vodafone, and O2 to deliver the strongest possible signal.
Our brand colour, Electric Indigo, reflects the energy and connectivity at the heart of what we do — bringing networks together so you never lose signal again.
Better for the planet
Every physical SIM card is a small piece of plastic that eventually ends up in landfill. With eSIM technology, there are no plastic cards to manufacture, ship, or throw away.
By going digital-first, Fuse reduces waste and eliminates the carbon footprint of physical SIM card logistics. Better signal and a smaller environmental impact — that's a win-win.
Our story so far
The idea is born
Frustrated by dead spots and single-network limitations, we set out to build something better. The concept for Fuse — a multi-network eSIM that fuses all four UK networks — takes shape.
Fuse Mobile launches
Multi-network eSIM coverage goes live across all four UK networks. Customers can sign up, pay, and activate their eSIM entirely online — no plastic SIM card needed.
Growing across the UK
Fuse reaches customers across the UK, with plans starting from £5.99 per month and roaming in 130+ countries. The mobile app launches on iOS and Android, giving customers full control of their eSIM from their pocket.
