Roaming, eSIM or local SIM: how to avoid surprise charges on your trip

You land, your phone connects to a local network on its own and days later a bill arrives that you did not expect. Avoiding it takes a few minutes of checking before you leave.

The most common options

Your carrier's roaming

It is the most convenient, but daily or usage rates vary a lot. Ask your carrier how it charges at your destination and whether there are packages.

eSIM or local SIM

They are usually cheaper for longer stays, but check that your phone is unlocked and compatible, and what coverage the chosen network has.

How to avoid surprises

Turn off what you don't use

If you won't use roaming, switch off mobile data abroad and use trusted Wi-Fi. Also turn off automatic updates.

Check your usage

Look at your phone's data counter and your carrier's alerts during the trip.
