France welcomes more international visitors than any other country, and for many of them the phone question is simple. If your SIM comes from an EU country, France is covered by the EU's Roam Like at Home rules, so your plan works much as it does at home. If you are arriving from the United States, the United Kingdom, Canada or Australia, roaming in Paris is usually charged by the day or by the megabyte, and a few days of maps and messages add up quickly.
There is a second group that gets caught out: travellers who cross one of France's borders without noticing. This guide covers both.
Key facts for France
- EU roaming: covered by Roam Like at Home
- Local networks: Orange, SFR, Bouygues Telecom, Free (depending on the plan)
- Emergency numbers: 112, medical emergencies 15, police 17, fire 18, text service for deaf and hard-of-hearing people 114, sea rescue 196
- Embassies: in Paris, with consulates in several large cities
The borders that charge
Most of France's neighbours are in the EU, but not all of them, and phones pick up whichever network is strongest.
Monaco is not part of the EU roaming area. On the coast between Nice and Menton, a phone can latch onto a Monaco network even if you never leave France, and an EU plan may charge for it. Andorra, high in the Pyrenees, is outside the EU roaming area too. Switzerland begins at the edge of Geneva, and the Eurostar takes you from Paris to London, where EU roaming rules no longer apply since Brexit.
If you travel near these borders, check your tariff or set your phone to a French network manually.
Overseas France: not all of it is the same
Guadeloupe, Martinique, French Guiana, Réunion, Mayotte and Saint-Martin are part of the EU, so Roam Like at Home applies there. French Polynesia, New Caledonia, Wallis and Futuna, Saint-Pierre-et-Miquelon and Saint-Barthélemy are outside the EU, and roaming there follows your operator's own prices. A plan for France does not automatically cover them, so check the destination before you fly.
Paris and getting around
In Paris you will use data constantly: metro and RER journeys, train tickets on your phone, museum time slots, restaurant bookings and ride-hailing or G7 taxis. Coverage is strong in the city and along the main rail lines; in the metro it varies by line and station. Outside the cities, the Alps, the Pyrenees and the Massif Central have stretches with weak signal, so download offline maps before a mountain drive.
Getting connected
From the EU: your home plan works under Roam Like at Home. A travel eSIM can still help if your tariff includes little data abroad or you are crossing into Monaco, Andorra or Switzerland.
From outside the EU: a travel eSIM is usually the simplest option. You install it at home with a QR code, its validity starts when it first connects in France, and your own number stays active for texts and WhatsApp calls over data.
A French SIM is sold in operator shops; you will need ID to register it.
Consular protection: who to call in France
- 112 works everywhere; 15 is for medical emergencies, 17 the police and 18 the fire service.
- If you cannot speak on the phone, 114 takes emergency requests by text message.
- 196 is for emergencies at sea.
- Embassies are in Paris and many countries have consulates in other large cities. The Telcomia app shows yours, with address and phone.
- Emergency phrases in French are ready to show on screen in the app.
Questions travellers ask about France
Does my EU phone plan work in France?
Yes. France is covered by Roam Like at Home, so you use your plan much as you do at home, within your tariff's terms.
Why did my phone switch to a Monaco network?
On the coast near Monaco, phones often pick up a Monaco network. Monaco is outside the EU roaming area, so charges can apply.
Which networks does a Telcomia eSIM use in France?
Orange, SFR, Bouygues Telecom or Free, depending on the plan, with 4G and 5G where available.
Is Réunion covered like mainland France?
Réunion is part of the EU, so Roam Like at Home applies. French Polynesia and New Caledonia are not.
The short version
From the EU, your plan covers France, but watch Monaco, Andorra, Switzerland and the Eurostar. From outside the EU, install a travel eSIM before you fly and switch it on when you land.
