What an eSIM is
An eSIM is a digital SIM built into your phone. You buy a data plan online, scan a QR code or tap an install link and you have mobile data in the country you visit, without a physical card or roaming fees. Outside your home region it is usually cheaper than roaming, and you can set it up before you fly. Here is how to do it and what to check first.
Check that your phone supports eSIM
Not every phone supports eSIM, and carrier-locked phones may block it.
How to buy and install an eSIM
The process takes about five minutes.
- Choose a plan by country or region, with the data amount and days you need.
- Buy the plan and install it while you are on Wi-Fi, ideally a day before you travel.
- Scan the QR code or follow the install link, then label the line, for example Travel.
- On arrival, switch on the eSIM line for mobile data and enable data roaming for it.
Compare eSIM providers
Prices and coverage vary by country, so compare for your route.
- Check device compatibility: Ensure your smartphone supports eSIM technology.
- Choose your eSIM provider: Select a reliable provider offering plans for your destination.
- Purchase an eSIM plan online: Buy before your trip to avoid being offline when you land.
- Check whether the plan allows hotspot sharing and whether it is data only or includes a phone number.
- Manage your eSIMs: Switch between home and travel profiles seamlessly.

Common mistakes
Most problems come from setup.
- Installing the eSIM only at the airport with no Wi-Fi.
- Forgetting to enable data roaming on the eSIM line.
- Deleting the eSIM profile after use; a deleted profile usually cannot be reinstalled.
- Not checking when validity starts: some plans start at install and others at first connection.
- Switch between profiles as needed for the best coverage.
