Most explanations of EU roaming rules are written for tourists taking a two-week holiday. A professional driver crossing four or five borders a week has different exposure — the exceptions and edge cases that barely matter to a tourist are exactly the situations a driver hits every month. Here is the regulation itself, laid out precisely.
The legal foundation
The current rule is Regulation (EU) 2022/612, a recast of the original 2012 regulation, guaranteeing free roaming across the zone until at least 2032. Retail roaming surcharges within the EU/EEA were abolished on 15 June 2017. As of 1 January 2026, Moldova and Ukraine joined the “Roam Like at Home” (RLAH) zone under bilateral agreements. Separately, in June 2026 the Council of the EU approved opening negotiations on free-roaming agreements with the six Western Balkans countries (Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia, Serbia) — a step toward eventual inclusion, but not yet the same as those countries being inside the zone.
| Date | Milestone |
|---|---|
| 15 June 2017 | Retail roaming surcharges abolished across the EU/EEA |
| 1 July 2022 | Recast regulation (EU) 2022/612 takes effect; wholesale data cap set at €2/GB, declining every year |
| 1 January 2025 | Wholesale data cap steps down to €1.30/GB |
| 1 January 2026 | Moldova and Ukraine join the RLAH zone; wholesale data cap steps down to €1.10/GB |
| 1 January 2027 | Wholesale data cap reaches its floor of €1.00/GB |
| 30 June 2032 | Current guarantee of free roaming within the zone runs at least to this date |
The Fair Use Policy formula, precisely
Operators may cap the data you can use at domestic prices while roaming, but only according to a specific formula: your monthly plan price excluding VAT, divided by the current regulated wholesale data cap, multiplied by two. If your operator’s resulting allowance is smaller than your domestic data allowance, you’re still entitled to use your full domestic allowance while roaming — the FUP formula sets a floor, not a hard ceiling below your normal plan.
Worked example (2026 cap of €1.10/GB): a €20/month plan (excl. VAT): 20 ÷ 1.10 = 18.18, × 2 = roughly 36.4 GB of guaranteed roaming data, even if the plan’s domestic allowance is smaller. Under the 2025 cap of €1.30 the same plan yielded about 30.8 GB — the same plan price now buys more roaming data purely because the wholesale cap fell.
Your operator is legally required to disclose your specific FUP allowance and to alert you when you reach 80% of it — usually by SMS. If you exceed it, any surcharge is capped at the same wholesale rate (plus VAT), never an arbitrary “roaming markup.”
The four-month monitoring window
To prevent someone from buying a cheap SIM in a low-cost country and using it permanently elsewhere, operators are permitted to monitor two indicators over a rolling four-month period: whether you spend more than 50% of your days abroad, and whether you consume more than 50% of your voice, SMS, or data usage abroad. If both indicators are triggered, the operator must first notify you and give you a period (commonly around two weeks) to adjust your usage pattern before any surcharge applies. This is specifically relevant to professional drivers, since spending most of a working month outside your home country is completely normal for the job but can look, on paper, exactly like the abuse pattern the rule was designed to catch.
Quality of service guarantee
A less-known part of the regulation: your operator must provide the same network quality abroad as at home, where the visited network technically supports it. If you have 5G at home, you’re entitled to 5G roaming where the local partner network offers it — operators are not permitted to silently downgrade roaming connections to 3G or 4G as a cost-saving measure, a practice that was common before this rule was tightened.
Emergency calls
Access to the European emergency number 112 is guaranteed free of charge in every roaming situation across the zone, even with no credit or an inactive plan.
Where the regulation stops applying entirely
The RLAH zone is 32 countries: the 27 EU member states, Iceland, Liechtenstein, Norway, Moldova, and Ukraine. Outside this exact list, none of the above protections apply by law — any roaming there is governed entirely by your operator’s own international rates, which some operators voluntarily discount but are not required to.
| Country | RLAH status |
|---|---|
| United Kingdom | Outside RLAH since Brexit (transition period ended 31 December 2020); some UK operators voluntarily retain EU-like roaming, but this is not guaranteed by regulation and varies by provider |
| Switzerland | Outside the EU/EEA, outside RLAH; standard international rates apply |
| Turkey | Outside RLAH; standard international rates apply |
| Serbia, Bosnia and Herzegovina, North Macedonia, Albania, Montenegro, Kosovo | Outside RLAH today. The Western Balkans states already have their own regional agreement removing roaming charges among themselves, and in June 2026 the EU Council approved opening negotiations on EU–Balkans free roaming — but until an agreement is in force, EU–Balkans roaming is still charged at standard international rates |
What this means in practice
Inside the 32-country zone, the protections are real, legally guaranteed, and enforceable through your national telecoms regulator if an operator gets it wrong. Outside that exact list, you are relying entirely on your operator’s goodwill and whatever international rate card they publish — which is precisely the situation where a route-specific data solution, sized to the actual non-EU leg of your trip, tends to be the more predictable choice.
Your rights if an operator gets it wrong
If you believe you’ve been incorrectly charged for roaming that should have been covered under RLAH, the regulation gives you a clear path: first, contest the charge directly with your operator, which is required to have a complaints procedure in place. If that doesn’t resolve it, you can escalate to your national telecoms regulator — in Romania, this is ANCOM (Autoritatea Națională pentru Administrare și Reglementare în Comunicații). This escalation path exists specifically because the EU designed RLAH as an enforceable consumer right, not a voluntary courtesy from operators.
Frequently asked questions
Does the Fair Use Policy apply to voice calls and SMS too, or only data?
The FUP mechanism as defined in the regulation applies specifically to data. If your plan includes unlimited calls and SMS domestically, that same unlimited allowance applies while roaming inside the RLAH zone, with no separate calculation.
What happens exactly when I hit my data FUP limit?
Your operator must have already warned you at 80% of your allowance. Once you exceed it, you can typically continue using data, but at a surcharge capped at the current EU wholesale rate plus VAT — never an arbitrary markup above that ceiling.
Is the wholesale cap the same as what I’d be charged?
The wholesale cap is the maximum operators can charge each other for cross-border data access, and by extension the maximum they can pass through to you as a FUP overage surcharge. It is a ceiling, not a guaranteed price — some operators charge less.
Will the Western Balkans join the RLAH zone in 2026?
The process is moving but not yet complete. In June 2026 the Council of the EU gave a green light to open negotiations on free-roaming agreements with the six Western Balkans countries (Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia, and Serbia). Opening negotiations is a step toward, not the same as, those countries being inside the zone — until an agreement is concluded and in force for a given country, roaming there still falls under standard international rates. Treat Balkans inclusion as an advancing but unfinished development, and verify the current status for the specific country before relying on it for a trip.
