Why Horizon
Buying one regional plan beats a separate eSIM per country and is far cheaper than roaming. Install once, top up if needed, and skip the local-SIM queues. Coverage runs at full speed on leading networks in each country for a dependable connection.
From 1 GB for a quick trip to unlimited for the long haul — pick exactly what you need.
Install in a couple of taps before you go, then it activates automatically when you arrive.
Plans typically around half the price of other eSIM brands — no surprise bills, no hidden fees when you land.
Add new destinations and top up on the same eSIM — no new install for your next trip.
We'll alert you as you approach your limit, so you can top up before you drop offline.
Single-country, Europe-wide, or worldwide coverage — full-speed data across borders and beyond.
Dozens of countries across the continent — the full, live coverage list is shown on this page. It's made for trips that cross several European countries on one plan.
Yes. The same eSIM stays connected as you travel between any of the covered countries — nothing to swap at the border.
Your regular SIM and number stay active for calls and texts — the eSIM adds data only. Scan the QR we email you, then turn the eSIM on when you arrive.
Walled old towns, island-hopping ferries and a coast road made for wandering — here's how to keep maps and bookings live all summer in Croatia.
The old town of Nessebar, long sandy beaches and prices that go further — here's how to stay online across a Bulgarian Black Sea summer.
