Compare France eSIM plans for CDG and Orly airport links, transfers between Paris stations and Nice rail connections. Review data, validity, listed territory, device support and total price.
A journey in France can begin with RER B at Charles de Gaulle, use Metro 14 or Orlyval at Orly, cross Paris between two mainline stations, or join regional rail through Nice Saint-Augustin. Each leg has its own departure point, ticket conditions and live operating information. Confirm the current flight terminal, departure station, hall and disruption notice with the relevant operator, then keep tickets, station names, the accommodation address and a backup route offline.

Before travel, open the order record on a second device and prepare the profile over stable Wi-Fi only at the point allowed by its guide. The selected product—not the destination—decides whether installation, activation or a specified first supported connection starts validity. At the instructed step, assign mobile data to the France eSIM and use only the roaming setting supplied for that plan. Disable automatic switching to the home line unless you mean to use it, and retain the support reference.

Important cities in France
Paris-Charles de Gaulle (CDG) · City guide
RER B is a central Paris link at Charles de Gaulle, while CDGVAL is currently described by the airport as a free inter-terminal connection. Aéroport Charles de Gaulle 1 and Aéroport Charles de Gaulle 2 TGV are distinct stations; the airport code or airline name alone does not select one. Confirm current flight information, terminal, station, disruption and transport ticket close to travel. Save the terminal, exact station, ticket evidence, Paris address and a route between them offline.
Paris-Charles de Gaulle (CDG) eSIM — online before you land →Paris-Orly (ORY) · City guide
Current operator information lists Metro 14 and Orlyval for Paris Orly Airport, subject to live operations and the ticket selected for the exact route. Airport ticket eligibility differs from ordinary city travel, so check the current Île-de-France Mobilités or RATP rule before boarding. An eSIM neither supplies nor validates that transport ticket. Do not retain an old fare, duration or frequency; save the terminal, stop, chosen ticket, validation instructions and destination address offline.
Paris-Orly (ORY) eSIM — online before you land →Paris: Gare du Nord · Gare de Lyon · Montparnasse · Bercy · Austerlitz · City guide
Gare du Nord, Gare de Lyon, Montparnasse, Bercy and Austerlitz are separate Paris stations. Read the booking for the exact departure station, hall and train rather than treating “Paris” as one rail terminal. A transfer across the city is a separate journey unless the ticket explicitly includes it; a high-speed reservation does not by itself settle local transport. Keep every station name in order, both ticket records, a realistic interchange plan and a backup route offline.
Paris: Gare du Nord · Gare de Lyon · Montparnasse · Bercy · Austerlitz eSIM — online before you land →Nice Côte d’Azur (NCE) · City guide
Nice Saint-Augustin and Nice-Ville are distinct stations. Nice Airport currently points to tram lines 2 and B between the terminals and Grand-Arénas, with Nice Saint-Augustin providing regional rail access; Nice-Ville requires a different city connection. Check the current airport, SNCF or TER journey close to departure rather than retaining a timetable. Save the intended station, terminal, tram stop, rail ticket or payment method, departure information and the final Nice address offline.
Nice Côte d’Azur (NCE) eSIM — online before you land →Why Horizon
A suitable plan helps reopen current flight information, compare an airport ticket with ordinary city travel, retrieve an SNCF booking and send the exact station name to a travel companion. It does not provide or validate a transport ticket, include a cross-Paris transfer, reserve a seat or prove that a phone is compatible with ticketing. Compare the offer's territory, data allowance, validity trigger, tethering, calls, texts, device support and total price before purchase.
Compare the listed data allowances and validity periods for your destination.
Install over reliable Wi-Fi before departure and follow the plan's activation instructions.
Review the current price, data, validity, coverage and fair-use terms before checkout.
When the selected plan supports reuse or top-ups, My eSIMs shows the eligible options for the installed profile.
We'll alert you as you approach your limit. If the plan supports a top-up, My eSIMs shows the eligible options.
Choose country, regional or global coverage and check every destination in the plan details.
Use the exact territory list in the selected offer. A France label alone does not establish service in Monaco, Corsica, Belgium, Switzerland, the rest of Europe or French overseas territories; geography and political status are not substitutes for product scope. Before any island, border or overseas leg, confirm that destination by name and keep tickets, addresses and safety information offline.
Read those three fields on the precise offer you intend to buy: its listed network, supported radio technology and any speed wording. Performance is affected by the phone, bands, settings, passenger load, station construction and local conditions, so no destination summary can promise a particular result. Review the product before payment and preserve the airport route, rail ticket and address offline.
Keep installation and the validity trigger as two separate checks. While stable Wi-Fi is available, follow the selected product's guide for adding the profile and store the QR code elsewhere. Its own terms must identify whether installation, activation or a particular first supported connection begins the period. Do not reuse timing from another offer, and avoid starting any instructed step early.
Look for each feature in the exact offer rather than treating it as standard eSIM behavior. Ordinary voice calls, SMS, a French number, OTP reception, tethering and top-ups must each be stated to be available. Internet apps can carry messages and app calls through data, but they do not create those telephone features. The home SIM is a separate service and may incur roaming costs whenever it handles voice, text or data.
No connection should be the only copy of a transport ticket or departure plan. Ticket eligibility, phone compatibility, validation, battery charge and live operations are separate from the eSIM. Before leaving Wi-Fi, store the valid ticket or payment method, current flight terminal, departure station, train and hall, address and alternate route. Recheck disruptions while data is available, but keep every leg usable without it.
Use Wi-Fi to compare the phone with the selected plan's instructions. Confirm the profile is enabled, France eSIM is the mobile-data line, home-line switching is off, and roaming plus APN match only the supplied values. Restart the phone, cycle airplane mode or select a network manually only when the supplied guide or support instructs you to do so. Capture the error, time and place for support and include the order reference. Do not delete the profile until support confirms restoration is possible.
