iPhone
One eSIM. Every UK network. Fuse auto-switches between EE, Three, Vodafone and O2 for the strongest signal — no contract, 7-day free trial, cancel anytime.
The UK's first multi-network eSIM. Fused.
Fuse connects you to EE, Three, Vodafone, and O₂ through one eSIM — automatically switching to the strongest signal, wherever you are. No more "no signal" moments. No more network lottery.
WHY FUSE
• Every UK network, one eSIM. Your phone fuses all four major UK networks into a single connection. When one drops, we switch you to the next strongest — automatically.
• See it happen in real time. Watch live network switches in your activity timeline. Know exactly which network is serving you, and when.
• Pay only for data. Flexible plans, no contract. Pause or cancel anytime. No commitments, no fine print.
• Live in 60 seconds. No SIM card, no store visit. Scan once, install, you're online.
• Honest usage tracking. See every byte and which network served you — broken down across EE, Three, Vodafone, and O₂.
• Real support. We usually reply in under 2 hours. No bots, no scripts, no queues.
CHOOSE YOUR PLAN
Three plans — light, regular, heavy — built around real UK data habits. Switch between them anytime from the app. See full pricing and allowances when you sign up at fusemobile.co.uk or in the app.
HOW IT WORKS
1. Choose your plan and check out at fusemobile.co.uk or in-app.
2. Install your Fuse eSIM in 60 seconds — direct install on iPhone, no QR code needed.
3. Your phone auto-connects to the strongest UK network. When signal drops, we switch you.
4. Manage your account, view usage, pause or change plan — all from the app.
DATA-ONLY eSIM
Fuse is a data-only service — you get cellular data, not voice calls or SMS. Use WhatsApp, FaceTime, iMessage, or any internet calling app for communication. Designed for the way people actually use phones in 2026.
