Why Fuse
What Fuse offers.
Strongest signal wins
Fuse scans all four networks continuously and moves to whichever is strongest in under a second. Talkmobile's Vodafone+Three dual-network access helps coverage but only across two carriers.
No EE or O2 dead zones
Areas where EE or O2 have stronger coverage than Vodafone/Three — your data goes weak on a Talkmobile plan. Fuse switches automatically.
Wider roaming reach
Fuse Pulse and Surge plans include data in 130+ countries. Talkmobile covers 48 EU/EEA destinations at no extra cost (fair-use policy applies; permanent roamers pay £7/week).
Fuse is a UK multi-network data-only eSIM — one digital SIM that uses all four UK networks (EE, Three, Vodafone, O2) and switches automatically to whichever has the strongest signal. Fuse does not issue a phone number; Talkmobile does. Most customers keep Talkmobile for calls and SMS on their existing number, and add Fuse alongside via dual-SIM to handle data.
Yes. Every eSIM-capable phone (most flagships from 2018 onwards) supports dual-SIM — one physical SIM and one eSIM, or two eSIMs. Keep Talkmobile for calls and SMS, install Fuse as a second eSIM for data. Both lines work at the same time.
No. Fuse is data-only — there is no number, no carrier voice calls, no SMS. Apps like WhatsApp, FaceTime, iMessage and Signal work normally over the Fuse data line. Your existing Talkmobile number stays where it is.
No — Fuse is rolling monthly. Cancel or change plan any month with no exit fees. Plans start at £5.99/month for Spark (5GB), £9.99 for Pulse (10GB plus roaming in 130+ countries), and £14.99 for Surge (15GB plus roaming).
