France eSIM guide: staying online in Paris and beyond
A travel eSIM is an easy way to have mobile data in France for metro routes, train tickets and maps. You install it before your trip and use it as soon as you arrive, with no physical SIM to buy.
Mobile networks in France
France has four main operators: Orange, SFR, Bouygues Telecom and Free Mobile. Coverage is excellent in Paris and other large cities, and 5G is available in many urban areas.
Rural areas, mountain regions such as the Alps and Pyrenees, and parts of the countryside can have weaker signal, so offline maps are useful for road trips.
How much data do you need in France?
A city break in Paris with maps, metro apps and messaging usually needs 3 to 5 GB per week. A longer road trip through several regions with constant navigation is more comfortable with 10 GB or more.
Practical tips for France
- Use public transport apps to check metro, RER and bus routes in real time.
- Store your SNCF train tickets in the app so you can show them on board.
- Download offline maps before driving through rural areas or the mountains.
- Many museums sell timed tickets online, which you can keep on your phone.
Setting up your eSIM before departure
Install the eSIM at home on Wi-Fi. On arrival, enable the eSIM line, turn on data roaming for it and choose it for mobile data, while your usual SIM stays on for calls and texts.
