EU Roaming Explained: Where Roam Like at Home Actually Stops (2026)

You drive out of Austria on a perfect alpine motorway, enter a tunnel, and come out in Switzerland. Nothing visible changes: same mountains, same road signs in German. But your phone knows. A text arrives with roaming rates that look nothing like the zero you have enjoyed all trip. This is the moment most travelers discover that EU roaming has edges, and that those edges do not match the map of Europe in their head.

What the EU roaming rules actually cover

The EU roam like at home regulation lets you use your home plan's calls, texts and data across the European Union without extra roaming charges. It also extends to the EEA countries: Norway, Iceland and Liechtenstein. So a SIM from any EU country works in Lisbon, Helsinki or Oslo just like it does at home. The problem is that plenty of places that feel completely European sit outside this zone, and the regulation stops dead at their borders.

The four famous gaps where roam like at home stops

• Switzerland is not in the EU or the EEA, so the regulation does not apply there, and Swiss roaming rates on EU plans are notoriously steep.
• The United Kingdom left the scheme after Brexit: coverage now depends on your individual carrier, and several charge daily fees to roam there.
• Turkey has never been part of roam like at home, so Istanbul is fully outside the zone even though half the city is geographically in Europe.
• The Western Balkans, meaning Albania, Bosnia, Serbia, Montenegro, North Macedonia and Kosovo, are all outside the regulation, so an EU SIM roams at full price there.

Switzerland is the gap that catches the most people, because it sits in the middle of the continent surrounded by roam-like-at-home countries. Cross from France, Germany, Austria or Italy and your free roaming ends at the border. The same trap works in reverse across the Balkans: drive from Croatia, which is covered, into Bosnia or Montenegro, which are not, and your data suddenly costs real money.

Fair use: roaming charges in Europe can appear even inside the EU

There is a second, quieter catch. Roam like at home was designed for holidays and business trips, not for living abroad on a foreign SIM. Every carrier applies a fair-use policy, and if you roam for long stretches, your operator can start adding surcharges even though you never left the EU. If you are spending a season working remotely from another EU country, do not assume zero roaming lasts forever.

The fix: one regional eSIM that ignores the borders

The clean solution is a regional eSIM that treats the continent as one place instead of a patchwork of regulations. The Kudo Europe + Region eSIM covers 46 countries, and the list deliberately includes exactly the places where roam like at home fails: Switzerland, the UK, Turkey and the non-EU Balkans. One plan, one price, no border anxiety.

• Plans start from 1 GB at EUR 1.20, valid for 45 days, with prices in EUR and VAT included.
• Validity starts only when the eSIM first connects abroad, so you can buy it at home before the trip at no cost.
• It works alongside your home SIM, so your number and WhatsApp keep working the whole time.
• You can top up inside the app on Europe + Region plans without installing a new QR code.
• Hotspot sharing is allowed on fixed-data plans, though not on the unlimited Pa Limit plans.

Setup takes less time than the border crossing itself. You buy online, the QR code appears instantly on screen and in your email, you install it under Settings > Add eSIM, and activation takes about 30 seconds. Kudo has been doing this since 2022 as the first eSIM provider from the Balkans, with support chat available and the site in 20 languages.

One exception inside the exception: Kosovo

Kosovo deserves its own note. It is outside EU roaming like the rest of the Western Balkans, but it is not included in the Europe + Region eSIM either. Instead, Kudo offers a dedicated Kosovo plan, so if Prishtina is your destination, that is the one to pick rather than the regional package.
