When you use your phone abroad, roaming charges apply. The cost depends on the country or region you are visiting.

We group destinations into different zones. Each zone has its own prices for calls, SMS, and data, so you always know what to expect before you travel.

Where to find all roaming costs

You can see the full list of countries, zones, and roaming prices on our roaming page:
