Why Fuse
What you get with Fuse that you don't with Sky Mobile.
Roaming included, not bolted on
Sky charges for a "Roaming Passport" outside the EU — £2 a day on top of your plan. Fuse includes data in 130+ countries in the monthly price on Pulse and Surge plans. No daily fee, no surprise bill.
Short contracts vs Sky's 24-36 months
Sky Mobile contracts run 24 or 36 months and tie you to the Sky ecosystem. Fuse is rolling monthly — leave any month, no exit fees, no contract you regret in year two.
eSIM-first, no shop visit
Sky still ships physical SIMs for most plans, with eSIM available only on selected newer contracts. Fuse is eSIM-first — order, scan a QR, connected in minutes.
