How to
eSIM for Travel: The Best Providers Compared
An eSIM gets your phone online the moment you land, far cheaper than roaming. How Airalo, Yesim and Saily compare and how to pick a plan.

Landing in a new country with no data is a self-inflicted wound — no map, no ride app, no way to reach your hotel. An eSIM fixes it: buy a plan before you go, and your phone connects the second you touch down, with no SIM swap and none of the roaming bill.
The providers worth comparing
- Airalo — the largest catalogue, with local, regional and global plans for 200+ countries.
- Yesim — strong global plans and pay-as-you-go flexibility.
- Saily — fast, simple plans from the team behind a major VPN.
Coverage and pricing differ by destination, so compare the plan for your specific country on our eSIM hub.
How to choose a plan
- Short city break: 1–3 GB is plenty for maps and messaging.
- Two-week holiday: 5–10 GB covers normal use including some streaming.
- Multi-country trip: a regional or global plan that works across borders.
Most travelers want data-only — calls go over WhatsApp or FaceTime anyway.
Set it up before you fly
Install the eSIM at home on Wi-Fi: buy the plan, scan the QR code, and switch it on when you land. You step off the plane already online, ready to book your airport transfer without hunting for airport Wi-Fi.
What we are watching
eSIM adoption is climbing fast as more phones support it and travelers realise how much roaming was costing them. Global and regional plans keep getting cheaper, making the airport SIM-card kiosk increasingly a thing of the past.
