When you travel to Hungary, your Fuse eSIM keeps you connected the moment you land. Roaming is included on Pulse and Surge plans — your data allowance works the same way it does at home, on whichever local network has the strongest signal.
How Fuse works in Hungary
Behind the scenes, Fuse partners with local carriers across Europe. The moment your phone detects Hungary networks, the eSIM hands off automatically. No menus, no SIM swap, no setup app — just open Maps, WhatsApp, your bank app, whatever you need.
Stay connected on day one
- No activation needed. Your existing Fuse plan covers Hungary.
- Use your usual data allowance. Browsing, maps, video calls — same as at home.
- No bill shock. When you hit your monthly cap, data stops (it doesn't auto-charge).
If your travel is heavy, the Surge plan gives you 15 GB of monthly data that works exactly the same way in Hungary as it does in the UK.
