Texts and data outside the EU: the 2026 guide to avoiding a €300 bill

Introduction: the invisible border that sends bills soaring

Since Roam like at Home came into force, an entire generation of travellers has settled into a comfortable habit: leave home with your phone, change nothing, and come back to find your plan untouched. It works perfectly from Lisbon to Helsinki. But there is an invisible border, rarely marked by anything more than a welcome text skimmed in passing: the one separating the "Europe and French overseas départements" zone from the rest of the world.

Beyond that line, the rules change radically. There is no European price cap any more, no wholesale rate framed by Brussels, no fair-use policy. There is a commercial contract between your French operator and a foreign one, and a pricing table that almost nobody consults before leaving. That is where three-figure bills are born — and sometimes worse.

In 2026, the DGCCRF and consumer associations still receive complaints every summer about non-EU roaming bills deemed incomprehensible. The problem is rarely a lack of information: it exists, and it is even sent by text on arrival. The problem is that it arrives too late, in a format that is far too dense, at a moment when the traveller is thinking about anything but a pricing table.

Where does your plan's "Europe" actually end?

First source of confusion: your operator's pricing zone matches neither the geography nor the political map of Europe.

The zone regulated by the European Union covers the 27 member states, plus — by agreement — Iceland, Norway and Liechtenstein (the European Economic Area). Most French operators voluntarily add the overseas départements and regions — Guadeloupe, Martinique, French Guiana, Réunion, Mayotte — to their "Europe and DOM" plans.

On the other hand, the following are not in that zone, contrary to what many people assume:

• The United Kingdom, now outside the EU: depending on the operator and the plan, it is sometimes brought back in commercially, sometimes billed as out of zone. It's the number one trap for trips to London.
• Switzerland and Andorra, outside the EEA, often billed separately despite their geographic position.
• Turkey, whose European portion makes no difference to billing.
• The overseas collectivities: French Polynesia, New Caledonia, Wallis and Futuna, Saint-Pierre-et-Miquelon are billed as international.
• Nearby enclaves: Monaco is generally treated separately, as are certain micro-states.

Simple rule: paying in euros or speaking French doesn't mean you're in your plan's Europe zone.

Each operator then carves the rest of the world into numbered zones (Zone 1, Zone 2, Zone 3…) or country groups. These divisions are not standardised: Morocco may sit in an intermediate zone with one operator and a far-flung zone with another. The only reliable source remains your operator's "calls, texts and data from abroad" price sheet, available on its website and in its app.

What a text or a megabyte really costs outside the EU

The orders of magnitude in 2026 remain stable — and brutal. Without a subscribed add-on, a French customer abroad outside the Europe zone is generally billed:

Usage	Common range outside the EU
Text sent	€0.20 to €0.80 each
Text received	Free in the vast majority of cases
Call made to France	€1 to €3 per minute
Call received	€0.50 to €2.50 per minute
Mobile data	€5 to €15 per megabyte
Data in maritime / airborne zones	Up to €20 per megabyte, or more

The figure to remember is the data one. At €10 per megabyte, a single automatic 50 MB app update costs €500. A thirty-second video sent over a messaging app can top €100. That is why French regulation has long imposed a safety cap on data abroad, generally set at around €50 excluding tax (roughly €60 including tax), beyond which the connection is cut until the customer confirms they wish to continue.

That cap is genuine protection, but it has two major blind spots. First, it applies only to data: premium-rate calls and texts are not capped. Second, some customers switch it off once, during an earlier trip, and forget to switch it back on. It's wise to check its status in your online account before every departure.

The three traps that drain a plan without you noticing

1. Maritime and airborne networks

This is by far the costliest scenario. On board a ferry, a cruise ship or an equipped aircraft, your phone may latch onto an onboard satellite network with identifiers such as MaritimeComms, OnMarine, AeroMobile or WMS. These networks fall under no standard roaming agreement and escape European regulatory caps.

Rates regularly reach several euros per minute of calling and several tens of euros for a few megabytes. The trap is especially vicious in the Mediterranean or the Channel: a phone that loses the terrestrial network switches automatically to the ship's network, sometimes just a few kilometres off the French coast.

2. Cross-border spillover

In border areas, radio waves ignore customs posts. Staying in Menton can flip a phone onto a Monegasque network; camping in the Pyrénées-Orientales can hook it up to an Andorran operator. The smartphone favours the strongest signal, not the cheapest.

3. Voicemail and call forwarding

An incoming call abroad that you don't answer is forwarded to your voicemail: that forwarding is an international call, and it is billed. Then listening to the message from abroad generates a second billed call. Two unwanted voicemails can therefore cost more than a night out at a restaurant.

Getting ready to leave: the ten-minute checklist

Most of the work happens before boarding, not on arrival. Here's the sequence to run through the day before you go.

1. Check the price sheet for your destination country. It gives the exact price of a text, a minute and a megabyte. Five minutes of reading that determine your whole strategy.

2. Check or activate the data cap. In your online account, under "options abroad" or "blocking out-of-plan usage".

3. Turn off data roaming. On Android as on iOS, the option sits in the mobile connection settings. It's the single most effective step on this list. Once it's off, the phone stays reachable for calls and texts but doesn't use a single byte without your consent.

4. Turn off automatic updates and photo syncing. Cloud backups, app updates and photo library syncing are the three main silent consumers.

5. Disable forwarding to voicemail, or at the very least warn family and friends that you won't be listening to voice messages.

6. Download whatever needs downloading before you leave: offline maps, playlists, travel documents, flight tickets, guides.

7. Plan a local connectivity solution. That's the subject of the next section.

One practical point comes up constantly on the ground: battery life. A phone permanently hunting for a foreign network drains far faster than it does at home. A 20,000 mAh USB-C power bank is probably the most cost-effective travel accessory there is, especially during long layovers or full days away from your accommodation.
