Data for Paris, the Alps, Provence and the coast, ready before you board. Install at home over Wi-Fi; the package starts when you land, not when you install it.
The France plan covers France only.
The same 10 GB in a package that keeps working past France.
38 other countries share the package with France. A few of them:
What's included, when it starts, and how to get connected.
Paris simplified its airport fares in 2026, and the rest of the country runs on the same railway. The first hour is mostly about buying the right thing once.
Install the onesim eSIM over Wi-Fi and leave the line off. Download an offline map of Paris, or of wherever you land — the RER platforms at Charles de Gaulle are underground and the signal is poor before you are above ground.
One Paris Région ↔ airports ticket, €14, covers Charles de Gaulle or Orly to anywhere in zones 1–5 with two hours of transfers. Children aged 4–9 pay half. Buy it at the station machines with a card, or load it onto a Navigo Easy card or your phone.
Settings → Mobile Data: switch the onesim line on, turn data roaming on for it, and select it as the mobile-data line. Leave your usual SIM in place with its roaming off so your own number still rings.
From Charles de Gaulle the RER B reaches Gare du Nord in about 30 minutes and Châtelet in 35. From Orly, metro line 14 now runs straight into the centre. Paper carnets are gone: journeys load onto a Navigo Easy card, €2, or onto the phone.
Residents of the European Economic Area pay €22; everyone else pays €32. Entry is timed and the museum closes on Tuesdays. Under-18s are free everywhere, and under-26s resident in the EEA are free at most national museums.
Fares rise steeply as the train fills, so book weeks ahead rather than days. Regional TER trains have flat fares and no reservation. SNCF strikes are announced in advance and the app shows the day’s running plan.
*Une carafe d’eau, s’il vous plaît* gets you a jug at no charge. Service is included by law; the tip is small change rather than a percentage. Terrace prices are higher than bar prices and both are posted.
Cities, motorways and the TGV lines are well covered. The Alps, the Pyrenees, the Massif Central and parts of Corsica have the usual mountain gaps on every network — download the route before you leave the valley.
Answers about data, coverage and setup for France.
Coverage follows the local networks wherever they reach — cities, transport corridors and most rural areas. Remote mountain and island areas can have weaker signal on any carrier.
No. onesim is installed before you travel, with nothing to register when you land. Turn on the onesim line for mobile data and you are connected.
Installing the eSIM does not start the clock. Your package starts the first time the eSIM connects to a network in a country it covers, even while mobile data is off. Install at home over Wi-Fi and keep the onesim line switched off until you arrive; if your home country is covered too, the package would start the moment the line connects there.
Yes. Your account has one onesim eSIM, and you refill it with any regional package from anywhere in the world — from the website or the app. The new package is added to the eSIM already on your phone; there is nothing to install again.
