All comparisons

The other eight.

vs Three

Great when Three has signal. When it drops, you drop. Fuse switches you to one of the other 3 networks automatically.

vs VOXI

VOXI is Vodafone-only. Fuse adds EE, Three and O2 to the mix — same eSIM, broader coverage.

vs Lebara

Lebara runs on Vodafone only. Fuse uses all four UK networks for stronger signal everywhere.

vs Tesco Mobile

Tesco Mobile is an O2 MVNO with 12 and 24 month contracts. Fuse uses all four UK networks, no contract, with global roaming included.

vs BT Mobile

BT Mobile is EE-only and pushes broadband bundles. Fuse adds three more networks and skips the bundle.

vs iD Mobile

iD Mobile is a Three MVNO. Fuse adds EE, Vodafone and O2 — same value, broader coverage.

vs Talkmobile

Talkmobile is Vodafone's budget brand on a single network. Fuse uses all four UK networks via eSIM for barely more per month.

vs Sky Mobile

Sky Mobile is best value bundled with Sky TV. Fuse is just mobile — four networks, no TV upsell, no 24-month contract.

The shortcut

What makes Fuse different.

  • All four UK networks. Most providers lock you to one. Fuse uses EE, Vodafone, Three and O2 and picks whichever has the strongest signal where you are.
  • No app restrictions. Some SIMs limit you to a few hundred approved apps. Fuse gives you full, unrestricted data — your favourite app, your VPN, anything.
  • No contracts. Monthly rolling. Cancel anytime in the app. Simple price, no hidden fees.
  • Data-only, designed for the way you actually use your phone. WhatsApp, FaceTime, iMessage — modern calling works over data. No clutter, just connectivity.
