The median week by home country, across every destination we track.

A carrier’s own country isn’t roaming, so it stays out of the median. Each destination has its own page with every carrier ranked.

Five routes worth a look

Where the gap between carriers, or between roaming and an eSIM, is widest.

EU–Western Balkans roaming declaration

Is 1 GB under 14.00€ yet?

In December 2022, operators from the EU and the Western Balkans signed a voluntary declaration to bring data roaming prices between the two down: at least one offer where 1 GB costs under €18 from October 2023, under €14 from 2026 and under €9 from 2028. Here’s what 1 GB costs at most, in every one of the six economies, on the carriers we track.

The declaration binds only the operators that signed it. Swiss, UK, US, Canadian and Australian carriers fall outside it. Rules
