EU Roaming Rules in 2026: Roam Like at Home, Fair Use and the Gaps
"Roam Like at Home" made European travel dramatically cheaper — but it has limits that catch out long-stay travellers, digital nomads and anyone leaving the EU by a hundred metres. Here is how it actually works.
If you have an EU or EEA mobile subscription, "Roam Like at Home" means you use your domestic allowance across the zone without extra charges. It is one of the genuinely good pieces of consumer regulation, and for a two-week holiday inside the EU it usually makes a travel eSIM unnecessary.
The limits are where it gets interesting.
What the rules cover
The EU roaming regulation applies to the 27 EU member states plus Iceland, Liechtenstein and Norway (the EEA). Within that zone, your operator must charge you domestic rates for calls, texts and data.
That is the rule. Now the exceptions.
Limit 1: fair use on data
Operators may apply a fair-use policy that caps how much data you get at domestic rates while roaming. If you have a large or unlimited domestic allowance, your roaming allowance can be substantially smaller.
The cap is calculated from your tariff, so a cheap unlimited plan often comes with a modest roaming data allowance. Beyond it, a regulated surcharge per gigabyte applies.
Practical effect: an unlimited domestic plan does not mean unlimited data in Spain. Check your operator's stated roaming allowance before a long trip.
Limit 2: permanent roaming
The rules are designed for travel, not for living abroad on a foreign SIM. Operators monitor usage and may apply a surcharge if, over a four-month window, you spend more time roaming than at home and use more data abroad than domestically.
If you get a warning message from your operator while abroad, that is what it is. You have a window to change the pattern before surcharges start.
Anyone spending months in another EU country — students, nomads, seasonal workers — should plan for this rather than be surprised by it. See eSIM for students studying abroad and your first month as an expat.
Limit 3: the zone is smaller than "Europe"
The roaming zone is not the continent. Outside it:
- United Kingdom — left the zone. Several operators reintroduced charges in both directions
- Switzerland — never in the EU or EEA
- Turkey, Serbia, Albania, Bosnia, Montenegro, North Macedonia, Kosovo, Moldova, Ukraine — outside
- Channel Islands, Isle of Man, Faroe Islands — outside
- Several EU countries' overseas territories — often outside
The full picture, including the countries travel plans get wrong, is in "Europe" eSIM plans: what is actually covered.
Limit 4: it only applies to your own subscription
Roam Like at Home is a rule about what your operator charges you. It does not make foreign networks free, it does not apply if you are not an EU/EEA subscriber, and it does not apply to a US, Australian or Asian SIM used in Europe.
Limit 5: calls to other EU countries are different
Roaming (you abroad, calling home) is covered. International calls (you at home, calling another country) are a separate, capped-but-not-free category. People conflate these constantly.
When an EU traveller still wants a travel eSIM
- Trips outside the zone — the UK, Switzerland, Turkey, the Balkans.
- Long stays where permanent-roaming rules bite.
- Small roaming fair-use allowances on cheap unlimited tariffs.
- Keeping work and personal data separate on one phone.
- A second line for a partner's phone or a tablet without adding to the family plan.
When a non-EU traveller comes to Europe
If you are arriving from the US, UK, Australia or Asia, none of this applies to you — your home carrier's international rates do. A regional Europe eSIM is almost always the cheaper route. See the maths in US carrier day passes vs a travel eSIM.
FAQ
Does my unlimited plan work unlimited in the EU? Usually not. Check your operator's roaming fair-use allowance.
Can my operator cut me off for roaming too long? They can apply a surcharge after a warning, under the permanent-roaming rules. They must warn you first.
Is the UK still covered? No. Check your operator's UK terms specifically — several charge again.
Do EU rules cover the Canary Islands? Yes, they are part of Spain for roaming. Some other overseas territories are not.
The bottom line
Inside the zone, for a normal holiday, your EU SIM is the cheapest option and you should use it. Outside the zone, on long stays, or on a cheap unlimited tariff with a small roaming allowance, a travel eSIM fills the gap — and costs a fraction of a surcharge.
