Best SIM and eSIM for France: data plans, Wi-Fi and phone tips

The right choice depends on how long you stay, whether you need a French phone number, and whether your phone is unlocked. Everything below assumes an unlocked handset; a locked phone can only use the SIM it came with, so sort that out at home first.

If you are in France for a city break or a two-week rail trip, an eSIM is simpler and usually cheaper than a shop visit. If you are staying a month or more, working, or need a French number for bookings and bank codes, a prepaid SIM from a French operator is worth the paperwork.

An eSIM is a digital SIM profile you install on your phone. You buy it online, scan a QR code or use the provider's app, and it activates when you reach France. There is no plastic to lose and no shop to find on arrival day. Most phones sold since about 2018 support eSIM, but check your exact model: some regional variants do not, and some carriers block eSIM on locked devices.

Two setups work well. You can run the eSIM for data only and keep your home SIM active for calls and texts, which is useful for bank codes and two-factor logins. Or you can make the eSIM your main line and turn your home SIM off entirely to avoid roaming charges. Either way, set the eSIM as the line for mobile data before you fly, and turn off data roaming on your home SIM.

Install the eSIM at home on Wi-Fi, not at the airport. Activation windows vary: some plans start when you install, others when you first connect in France. Read that detail before you buy, because a plan that starts on install can burn days before you land.

Orange, SFR, Bouygues Télécom and Free all sell prepaid SIMs in their own shops, and some are also sold at tabacs. You need photo ID to register the line; this is a legal requirement, not a shop policy. Bring your passport. Registration is quick but the queue is not, so budget an hour in a city-centre branch.

Prepaid credit usually lasts a set period, often 30 days, and you top up in shops, at tabacs or online. Data allowances on French prepaid plans are generous by international standards, and the price gap between operators is wide, so compare two or three before committing. Airport and tourist-area shops often charge more than a branch in a residential neighbourhood.

The main reason to choose a physical SIM over an eSIM is the French number. It helps with restaurant reservations, delivery apps, and any service that sends an SMS code. If you do not need that, the eSIM route is faster.

France uses GSM and LTE/5G networks on standard European bands, so most phones from the US, UK, Canada, Australia, New Zealand and Ireland work fine once unlocked. The two things that trip people up are carrier locks and eSIM support.

A carrier-locked phone will not accept a French SIM or a travel eSIM. Ask your operator to unlock it before you leave; in many countries they must do this free once the device is paid off. For eSIM, check your model number rather than the model name, because the same phone can ship with and without eSIM support in different markets.

Charging is the other practical point: France runs on 230 V at 50 Hz with type C and type E sockets. US and Canadian devices need a plug adapter and, for anything with a motor or heating element, a voltage converter. Phones, laptops and camera chargers are usually dual-voltage and only need the adapter.

Wi-Fi is easy to find in France. Most hotels, cafés, fast-food chains and SNCF stations offer it free, and many TGVs have onboard Wi-Fi, though it can be slow in tunnels and on busy services. Paris has public Wi-Fi in parks and libraries. Treat public networks as unsecured: avoid banking on them, or use your phone's data instead.

For calls home, WhatsApp is widely used in France, and video calls over data work well on 4G and 5G. SMS is still used for booking confirmations and bank codes, which is one reason to keep your home SIM active for texts. If you need to call a French landline or mobile, dial +33 and drop the leading 0 from the local number.

Coverage is strong in cities and along main rail lines, but rural areas, deep valleys and high mountain routes can drop to 3G or no signal. If you are driving in the Alps, the Pyrenees or rural Occitanie, download offline maps before you set off. Monaco is a separate network, so an EU roaming plan may not cover it.

Prices move constantly, so treat the figures below as bands rather than quotes. Travel eSIMs are usually sold per trip or per month with a fixed data allowance, and the per-GB price falls sharply as the allowance grows. French prepaid SIMs are sold as a SIM card plus a top-up, and promotional pricing is common, especially online.

One trap: a cheap eSIM with a small data allowance can run out mid-trip, and topping up is not always possible. If you plan to use maps, translation and video calls daily, estimate your usage honestly and buy one tier above it. A second trap is buying at the airport, where both physical SIMs and eSIM resellers charge a premium.

Keep your home SIM active if you need bank codes or two-factor authentication, but switch off its data roaming. If your bank sends codes by SMS, a data-only eSIM will not receive them.

Save your eSIM QR code and your provider's support link offline before you fly. If activation fails at the airport, you want the fix available without Wi-Fi. Also note the French emergency numbers: 112 works from any phone, including foreign SIMs, and 15 is medical, 17 police, 18 fire.
