EU roaming explained: what roam like at home covers, where it stops, and when a travel eSIM still pays off
EU roaming explained: what roam like at home covers, fair-use limits, the European countries it does not include, and when a travel eSIM is cheaper.
If your SIM card is from an EU country, EU roaming lets you use your normal calls, texts and data in the other EU countries, Iceland, Liechtenstein and Norway at no extra cost, so for most trips inside that area you do not need a travel eSIM. You still need one, or at least should compare, in three situations: when your plan has a low fair-use limit for data abroad, when you travel to European countries outside the rules, such as Switzerland, the UK, Turkey or the Western Balkans, and when your SIM is from outside the EU. This guide explains the rules and, with data from the Europe plans in our database, shows which countries travel eSIMs cover.
Quick answer: do you need a travel eSIM in Europe?
| Your SIM card | Where you travel | Travel eSIM? |
|---|---|---|
| From an EU or EEA country | Other EU countries, Iceland, Liechtenstein, Norway | Usually not, unless your fair-use limit is low |
| From an EU or EEA country | Switzerland, UK, Turkey, Balkans, Monaco, Andorra | Often yes; check your tariff first |
| From the UK or Switzerland | EU countries | Often yes, unless your plan includes Europe |
| From outside Europe | Anywhere in Europe | Almost always the cheaper option |
Whatever your situation, check two things before you leave: what your own tariff says about roaming, and whether every country on your route is covered.
How EU roaming works: roam like at home in 30 countries
Since 2017, the EU's roaming rules, known as “roam like at home”, have banned extra roaming charges inside the European Economic Area. In 2022 the rules were extended until 2032. In practice:
- Where they apply: the 27 EU countries plus Iceland, Liechtenstein and Norway. That includes the EU's outermost regions, such as the Canary Islands, Madeira, the Azores and the French overseas departments.
- What you get: your normal calls, SMS and data at your domestic price, using your home allowance.
- Who it applies to: customers of mobile operators in those 30 countries. The rules protect the SIM card, not the passport: a tourist with a US, UK or Swiss SIM does not benefit.
- Quality: the rules also require the same quality of service abroad where the visited network can offer it, for example 4G or 5G instead of an older network.
- Information: when you arrive in another EU country, your operator sends a free SMS with your roaming conditions and a reminder of the emergency number 112.
For a weekend in Paris with a German SIM, or a beach holiday in Spain with an Italian one, roaming therefore costs nothing extra. Our guide eSIM vs roaming vs local SIM compares roaming with the alternatives in general.
Fair use: the limits in the small print
“Roam like at home” does not always mean “unlimited like at home”. The rules allow operators two kinds of limits:
- Data limits on cheap or unlimited plans: if your plan includes a lot of data for little money, your operator may cap the data you can use abroad. The minimum allowance is calculated with a formula set in the EU rules and is stated in your tariff, often as “EU roaming data”. Above it, a small regulated surcharge per gigabyte applies. Look for it in your contract summary or on your operator's roaming page; the welcome SMS you receive abroad usually mentions it too.
- Permanent roaming: the rules are meant for travel, not for living abroad on a foreign SIM. If, over a period of several months, you spend most of your time and use most of your data abroad, your operator may warn you and then start charging.
For a normal holiday, the second point does not matter. The first one can: an unlimited home plan may come with an EU roaming limit of only a few gigabytes. If you plan to stream, work online or share your connection on a longer trip, a travel eSIM for the extra data can be cheaper than the surcharge. Our guide How much data do I need for travel? helps you estimate your use.
Where EU roaming does not apply, and how travel eSIMs cover it
Several popular European destinations are outside the rules, even if they use the euro or have no border controls. Your operator may still include some of them voluntarily, but many tariffs charge extra. The table shows how often the more than 3,800 Europe plans in our database include them:
| Country | Share of Europe plans that include it |
|---|---|
| United Kingdom | more than nine in ten |
| Switzerland | about four in five |
| Turkey | about two in three |
| Ukraine, Moldova, Serbia | between two in five and a little over half |
| Albania, Montenegro, San Marino, Gibraltar | about one in three |
| Bosnia and Herzegovina, North Macedonia, Faroe Islands, Jersey, Guernsey, Isle of Man | about one in five |
| Andorra, Georgia | one in ten or fewer |
| Kosovo, Monaco | fewer than one in twenty |
For the UK and Switzerland, almost any Europe plan works. For the Balkans, Monaco or Andorra, check the country list carefully or buy a plan for that country; our database lists several hundred country plans for each of them, for example for Switzerland, Monaco or Andorra. For a trip through several Balkan countries, a Balkans regional plan is often the better fit.
Ferries, cruise ships, planes and border areas
Even inside the EU, some situations are not covered by roam like at home:
- Ships and planes: on ferries, cruise ships and some flights, phones can connect to on-board networks via satellite. These are not covered by the EU rules and can be very expensive. Switch off data roaming on your home SIM or use airplane mode with Wi-Fi; see eSIM for cruises.
- Border areas: near Switzerland, Monaco or the Balkans, your phone may connect to a non-EU network while you are still in the EU, for example on the shores of Lake Geneva. Set network selection to manual and choose a network of the country you are in.
- Non-EU territories: the Faroe Islands and Greenland belong to Denmark but are not in the EU, and Jersey, Guernsey and the Isle of Man were never part of the EU. Check your tariff for each of them.
UK, Swiss and other non-EU SIM cards: why a Europe eSIM makes sense
If your SIM is from outside the EU, roam like at home does not apply to you at all. Many UK and Swiss operators charge a daily fee in the EU unless your plan includes Europe, and operators from other continents usually charge by the day or by the megabyte. A Europe eSIM is then usually the cheaper option:
- Wide choice: our database lists more than 3,800 Europe plans from 38 providers; the typical one covers about 35 countries.
- Not all EU countries in every plan: only about seven in ten Europe plans cover all 27 EU countries. France and Poland, for example, are missing from around one in seven. Check the list if your route includes them.
- Combined trips: close to 2,900 Europe plans cover Switzerland together with France, Italy, Germany and Austria, and more than 3,100 cover the UK together with France, Spain and Italy.
- Price: per gigabyte, a Europe plan costs only a little more than a country plan for the UK or Switzerland, so for a trip through several countries it is the simpler choice.

Practical tips for roaming in Europe
- Check your tariff for the EU roaming data limit and for the countries outside the EU that it includes.
- List every country on your route, including day trips and stopovers.
- Decide per country: roaming where it is free and the limit is enough, a travel eSIM where it is not.
- Keep your home SIM for calls and SMS, and switch off data roaming on it if the travel eSIM handles data; see Dual SIM with a travel eSIM.
- On ferries and near borders, watch which network your phone is using.

Questions travellers ask
Which countries are covered by EU roaming?+
The 27 EU countries plus Iceland, Liechtenstein and Norway, including the EU's outermost regions such as the Canary Islands, Madeira, the Azores and the French overseas departments. Switzerland, the UK, Turkey, Monaco, Andorra and the Western Balkans are not covered.
Does EU roaming work in Switzerland?+
No. Switzerland is not in the EU or the EEA, so the EU rules do not apply. Some EU operators include Switzerland in their roaming zone anyway, but many charge extra. About four in five Europe travel eSIM plans in our database include Switzerland.
Does EU roaming work in the UK after Brexit?+
Not under the EU rules. Whether you pay extra in the UK with an EU SIM, or in the EU with a UK SIM, depends on your operator. More than nine in ten Europe travel eSIM plans in our database include the UK.
Is there a data limit when roaming in the EU?+
There can be. On cheap or unlimited plans, operators may set a fair-use limit for data used abroad, calculated with a formula in the EU rules. The limit is stated in your tariff; above it, a small regulated surcharge per gigabyte applies.
Do I need a travel eSIM in the EU if I have an EU SIM card?+
Usually not. Roam like at home lets you use your normal allowance. A travel eSIM is worth it if your EU roaming data limit is too low for your plans, or if your trip includes countries outside the rules, such as Switzerland, Turkey or the Balkans.
Does EU roaming apply on ferries and cruise ships?+
No. On board, phones can connect to the ship's own maritime network, which is not covered by the EU rules and can be very expensive. Switch off data roaming on your home SIM at sea and use the ship's Wi-Fi if you need internet.
