The written walkthrough

The surprise roaming bill: the written walkthrough

Two weeks of Greek islands, a phone used exactly as at home, and an 84 € line on the bill when you get back. The Regulation says the opposite: within the Union your plan travels with you at the domestic price, and the exceptions are written, framed and notified.

Law as verified onJuly 29, 2026

This walkthrough contains the answers. It is here so you can read the situation without playing it, print it, and so the content stays complete without JavaScript.

Item no. 1 · The border text message

The plane touches down in Athens. By the time you collect your bag, your phone has already found a local network, and a text message is waiting.

Two weeks of islands are waiting too. The phone question gets settled now.

Text from your operator9:04 am, visited network

Welcome to Greece. Your calls, texts and data come out of your plan just like in France, within our fair use policy.

Watch out for value-added numbers and special services, which can cost more. Emergency number: 112.

Your app also offers the Europe Holiday Pack at 3 € a day, for total peace of mind.

A reassuring text, and a paid option “for peace of mind”. What do you do?

Correct answer · I keep the text, note what it says about my fair use policy, and use my phone normally.

That text is not a courtesy: it is compulsory, and it informs you At every border within the Union, your operator must send you this message: it confirms you are roaming, reminds you of its fair use policy, your personalised pricing, the services that can generate additional charges, and the country's emergency contacts. It is your reference exhibit: keep it.

“Whenever you cross a border within the EU, you should get a text message from your mobile operator informing you that you are roaming, and reminding you of its fair use policy. The text message should inform you about personalised pricing based on your subscription, any services that can generate additional charges, and the emergency contacts for that country.”

In plain words: the border text is a right, not a commercial gesture. What it announces binds them more than it binds you: keep it.

Myth · Roaming is expensive by definition: I switch off data and the phone stays at the bottom of the bag.

The myth: “abroad always costs extra” It is the most durable phone myth in travel, and it is ten years out of date. Within the Union, the official page says it plainly: no additional charges for using your mobile phone in another EU country. Calls, texts and data are charged at domestic rates, just like at home, incoming included.

“When you travel outside your home country to another EU country, you don't have to pay any additional charges to use your mobile phone. This is known as "roaming" or "roam like at home".”

In plain words: your plan crosses the Union's borders with you, at the same price. Cutting your data out of fear means paying for a right in order not to use it.

Introductory section of the page · Roaming: using a mobile phone in the EU, the principle · https://europa.eu/youreurope/citizens/consumers/internet-telecoms/mobile-roaming-costs/index_en.htm

Myth · I activate the Europe Holiday Pack at 3 € a day: better safe than sorry.

The myth: “the paid option protects me” The default regime already is your plan at the domestic price. Operators may offer specific roaming contracts, at tariffs which fall OUTSIDE the scope of EU rules, and the official page states the point that matters: you must specifically choose those options yourself. By activating the pack, you walk out of the protected regime into a house product.

“Operators may also offer contracts without roaming services or specifically designed alternative roaming contracts with tariffs which fall outside the scope of EU rules […] You must specifically choose these types of options yourself.”

In plain words: nobody can push you out of the European regime by default, but you can walk out of it with one tap. The peace-of-mind pack is precisely that tap.

Item no. 2 · Seven hours of ferry

Second island. The ferry leaves the port, the coast recedes, and a discreet notification changes everything at the top of the screen: the network name is no longer the same.

Network statusAt sea, upper deck
Previous network
Greek land-based operator
Current network
MARITIME-SAT-7
Type
the ship's satellite network
Pricing
not displayed

Still between two ports of the Union, but no longer the same network. What does that change?

Correct answer · Flight mode for the crossing: a satellite network is not covered by the Regulation.

The Regulation stops where the satellite begins At sea as in the air, the rule is written: as long as your phone is connected to a terrestrial network, harbour, river, airport, the domestic rate applies. But if the services come through satellite systems, EU rules no longer apply, and prices are no longer capped. The official page itself gives the countermove: deactivate roaming or activate flight mode.

“But if mobile services are provided via satellite systems, EU rules no longer apply and you will be charged for non-regulated roaming services (no price caps). To avoid extra costs, deactivate roaming on your device or activate flight mode while on board.”

In plain words: the ship's network is not a Union network like the others. Seven hours of flight mode cost zero; seven hours of satellite cost whatever the ship decides.

Section “Can I roam while travelling by ship or plane?” · Roaming: ships, planes and satellite networks · https://europa.eu/youreurope/citizens/consumers/internet-telecoms/mobile-roaming-costs/index_en.htm

Myth · I am between two Greek islands, so inside the Union, so at the domestic rate: I keep sending my photos.

The myth: “inside the Union, therefore protected” The protection does not follow the map, it follows the NETWORK. On a terrestrial mobile network your domestic rate applies, even out at sea if the coast reaches that far. But the ship's network is a satellite system: EU rules no longer apply, and nobody caps the prices. Geography does not protect you; the connection does.

“You should not be charged extra to use your mobile phone when you travel by ship or plane, as long as you are connected to a terrestrial (land-based) mobile network, e.g. in a harbour, on a river, in the airport. But if mobile services are provided via satellite systems, EU rules no longer apply and you will be charged for non-regulated roaming services (no price caps).”

In plain words: look at the network name, not the map. Terrestrial: covered. Satellite: no more caps.

Section “Can I roam while travelling by ship or plane?” · Roaming: ships, planes and satellite networks · https://europa.eu/youreurope/citizens/consumers/internet-telecoms/mobile-roaming-costs/index_en.htm

Myth · My operator has a duty to protect me from any satellite connection: I risk nothing, they will block it.

The myth: “the operator will block it for me” The text imposes REASONABLE steps, not an absolute shield: the operator must protect you from charges caused by inadvertently connecting to non-terrestrial networks, for example by letting you opt out of them. Where that mechanism exists, you can activate it at any time, easily and free of charge. But the decision to cut remains a gesture, and the gesture is yours.

“7. Roaming providers shall take all reasonable steps to protect their customers from paying additional charges for data services for inadvertently connecting to non-terrestrial public mobile networks, such as enabling roaming customers to opt out of connecting to non-terrestrial networks. Where such an opt-out mechanism is offered, the customer shall have the right to opt out from the use of non-terrestrial networks at any time, easily and free of charge, and to request the reinstatement of the connection to such networks.”

In plain words: ask your operator for the non-terrestrial network block if they offer one, it is free. But do not bet your bill on an automatic block the text does not impose.

Item no. 3 · The 80 % alert

Back on dry land. Two text messages arrived during the crossing, and the second one asks for a decision.

Texts from your operatorReceived during the crossing

Usage info: you have reached 80 % of your data roaming spending limit (default limit: EUR 50 excluding VAT per monthly billing period).

Limit almost reached. To CONTINUE using data roaming beyond the limit, follow the instructions: reply YES to this message. Cost of each additional unit: see link.

Without a reply from you, data roaming services will be interrupted.

Reply YES, or do nothing?

Correct answer · I do not reply: without a reaction from me, both the service and the billing stop on their own.

Your silence protects you: it is written into the mechanism The safeguard limit works in your favour: a default financial limit close to, but not exceeding, EUR 50 of outstanding charges per monthly billing period, excluding VAT, an alert at 80 %, another when it is about to be exceeded, and above all the final rule: if you do not respond as prompted, the provider immediately ceases to provide AND to charge. The bill cannot take off while you are watching the sea.

“One of those limits (the default financial limit) shall be close to, but not exceed, EUR 50 of outstanding charges per monthly billing period, excluding VAT. […] If the roaming customer does not respond as prompted in the notification received, the roaming provider shall immediately cease to provide and to charge the roaming customer for regulated data roaming services, unless and until the roaming customer requests the continued or renewed provision of those services.”

In plain words: at the limit, everything stops, unless you expressly ask for more. Not replying is a protection, not a negligence.

Article 14(4) · Regulation (EU) 2022/612, Article 14 (Transparency and safeguard mechanisms for data), paragraph 4 · https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022R0612

Myth · These alert texts are marketing in disguise: I delete them without reading.

The myth: “alerts are spam” These notifications are a cog of the Regulation, not a campaign: the operator must alert you directly on your device when your consumption reaches 80 % of the agreed limit, financial or in volume. They are what hands you control over what happens next. Deleting them unread is throwing the dashboard out of the car at full speed.

“Each roaming provider shall also ensure that an appropriate notification is sent directly to the roaming customer's mobile device, for example by an SMS message, an email, means of a text message or a pop-up window on the computer, when the data roaming services have reached 80 % of the agreed financial or volume limit.”

In plain words: the 80 % alert is an obligation on the operator and information for you. It is the opposite of an advertising message.

Article 14(4) · Regulation (EU) 2022/612, Article 14 (Transparency and safeguard mechanisms for data), paragraph 4 · https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022R0612

No effect · I reply STOP to all my operator's messages, once and for all.

You can switch the alerts off, which is exactly why you should not The text really does give you that right: on the occasion of each message, you can give notice, free of charge, that you do not require the automatic message. It also gives you the reverse right: to have it back at any time, free of charge. What just happened is therefore not an infringement, it is an own goal. Reinstate the service, it works for you.

“On the occasion of each message, customers shall have the opportunity to give notice to the roaming provider, free of charge and in an easy manner, that they do not require the automatic message. Customers who have given notice that they do not require the automatic message shall have the right at any time and free of charge to require the roaming provider to provide the service again.”

In plain words: switching the information messages off is a right, and so is switching them back on. The second one is the better idea.

Article 13(1), fifth subparagraph · Regulation (EU) 2022/612, Article 13(1), fifth subparagraph (declining the automatic message, having it back) · https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022R0612

Item no. 4 · The extra line

Three weeks later, the bill arrives. Your usual plan, and just below it, a brand-new line.

Monthly billCustomer area
Monthly plan
usual amount, unchanged
European Union roaming
84 €
Stated reason
you exceeded your fair use limit
Notification of that excess during the trip
no trace in your messages

84 € for an “excess” nobody ever notified you about. What do you do?

Correct answer · I dispute it: a fair use excess must be notified BEFORE it is billed, with the surcharge rate.

A surcharge without prior notification has a birth defect The mechanism is written in order: when the fair use volume is fully consumed, the operator sends a notification, and that notification states the surcharge that will apply to any additional consumption. An 84 € line that appears straight on the bill, without that alert ever existing, skips a step the text does not allow to be skipped.

“3. The roaming provider shall send a notification when the applicable fair use volume of regulated data roaming service is fully consumed or any usage threshold applied in accordance with Article 6 is reached. That notification shall indicate the surcharge that will be applied to any additional consumption of regulated data roaming services by the roaming customer.”

In plain words: first the alert with the rate, only then the surcharge. A bill that invents the missing step gets disputed with the exhibits in hand.

Article 14(3) · Regulation (EU) 2022/612, Article 14 (Transparency and safeguard mechanisms for data), paragraph 3 · https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022R0612

Myth · I did use the phone a lot over there: a surcharge is in the natural order of things.

The myth: “heavy use, deserved surcharge” The principle is no surcharge on top of the domestic price, for calls made or received, texts and data, and even for activating the service abroad. The only exits are Articles 5 and 6: a fair use policy that respects your volumes, or exceptional charges authorised by the regulator. Intensive use of your own plan is neither.

“1. Roaming providers shall not levy any surcharge in addition to the domestic retail price on roaming customers in any Member State for any regulated roaming calls made or received, for any regulated roaming SMS messages sent or for any regulated data roaming services used, nor shall they levy any general charge to enable the terminal equipment or service to be used abroad, subject to Articles 5 and 6.”

In plain words: a surcharge is never “the natural order of things”: it is the exception, and it must fit a written frame. Outside that frame, the line gets disputed.

Article 4(1) · Regulation (EU) 2022/612, Article 4 (Provision of regulated retail roaming services), paragraph 1 · https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022R0612

Myth · An issued bill cannot be disputed: the system calculated it, I pay.

The myth: “the machine billed it, so it is settled” The official page of the Union provides for exactly this moment: if you think your operator has not respected your rights, you contact it and use its complaint procedure. And it names the next step: if the answer does not satisfy you, the national regulatory authorities will handle your case. A bill is an assertion, not a judgment.

“If you think your service provider has not respected your rights, you should contact your operator and use the complaint procedure in place. If you are not satisfied with their response you can contact the relevant national regulatory authorities in your country, usually your national telecoms regulator, who will handle your case.”

In plain words: the complaint is the normal path, in two steps: the operator first, the authority next. Paying in silence closes both.

Item no. 5 · The operator's answer

Twelve days after your complaint, the answer lands. It is friendly, final, and it quotes its own terms and conditions.

Reply from customer serviceComplaint R-2318-K

Our terms and conditions, article 12, define our fair use policy. The volume you used while roaming exceeds the one provided for your offer.

No individual notification is required: our terms are available online at all times.

The billing therefore stands. We remain at your disposal.

“Our terms and conditions provide for it.” Their last word, not necessarily yours. Where do you go?

Correct answer · I refer the matter to my country's national regulatory authority, complete file attached.

This Regulation has guardians in every country, and they can be seised The Regulation entrusts its own supervision to the national regulatory authorities: they monitor and supervise compliance within their territory, and they strictly monitor operators who avail themselves of the fair use articles. The official page of the Union says the same thing from the user's side: after the operator, they are the ones who handle your complaint.

“1. National regulatory authorities and, where applicable, other competent authorities shall monitor and supervise compliance with this Regulation within their territory.”

In plain words: an operator invoking fair use is precisely under the eye of its country's authority. Your file has an address.

Article 17(1) · Regulation (EU) 2022/612, Article 17 (Supervision and enforcement), paragraph 1 · https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022R0612

Myth · Their terms and conditions define their policy: whatever they provide applies, full stop.

The myth: “the terms and conditions prevail” A fair use policy is not free-form text: the Regulation sets its floor. Any fair use policy must enable customers to consume, at the domestic price, volumes consistent with their tariff plans. A house clause that shaves your plan below that floor does not become valid because it sits online “at all times”.

“Any fair use policy shall enable the roaming provider's customers to consume volumes of regulated retail roaming services at the applicable domestic retail price that are consistent with their respective tariff plans.”

In plain words: their policy must respect your plan, not the other way round. The Regulation frames their terms and conditions, and not the reverse.

Article 5(1) · Regulation (EU) 2022/612, Article 5 (Fair use), paragraph 1 · https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32022R0612

Myth · A telecoms authority will not bother with my 84 €: those counters are not for private individuals.

The myth: “too small for the authority” The official page of the Union describes that counter for exactly your case: the operator first, through its complaint procedure, then, if the answer does not satisfy you, the relevant national regulatory authorities in your country. The text sets no minimum amount anywhere: what is at stake is compliance with the Regulation, not the size of the line on your bill.

“If you are not satisfied with their response you can contact the relevant national regulatory authorities in your country, usually your national telecoms regulator, who will handle your case.”

In plain words: the authority handles complaints from private individuals, it is written. 84 € and a principle already make a case.

Section “If things go wrong - your consumer rights” · Roaming: the complaint, from the operator to the national authority · https://europa.eu/youreurope/citizens/consumers/internet-telecoms/mobile-roaming-costs/index_en.htm

Verdict · What the 84 € line was worth

A border text kept, a ferry crossed in flight mode, an alert respected, a bill disputed with the exhibits in hand, and six rights that travel across the twenty-seven countries with your plan.
