Fuse vs BT Mobile

BT Mobile is the EE-powered SIM service from BT. It's reliable where EE is strong, but you're locked to one network and BT loves to bundle mobile with broadband. Fuse gives you all four UK networks, no contracts, and no upsell.

Why Fuse

What you get with Fuse that you don't with BT Mobile.

Not tied to one network

BT Mobile is an EE MVNO — every BT SIM uses the EE network and only the EE network. Fuse uses all four UK networks through a single eSIM, automatically switching to the strongest signal.

No broadband bundle pressure

BT pushes you toward bundling mobile with home broadband. Fuse is just mobile — clean monthly pricing from £5.99, no upsell to a TV package you don't need.

Wider roaming, no caps

BT roams in around 47 destinations beyond the EU. Fuse roams in 130+ countries on Pulse and Surge, included in the monthly price — no daily roaming fees, no fair-use caps surprising you on holiday.

Rolling monthly contracts

BT contracts are 12 or 24 months with exit fees. Fuse is rolling monthly — keep using it as long as it works for you, cancel any time with no penalty.
