eSIM France and Europe: which SIM card to choose for travelling
An eSIM installs in a few minutes before departure and connects you as soon as you arrive in Nice, without going through a shop. Here's how to choose a France/Europe data plan, activate it and avoid unpleasant surprises.
Staying connected in Nice now costs just a few euros: a travel eSIM is bought online and works as soon as you land, with excellent 4G/5G coverage. This guide compares options for a stay in France or Europe, eSIM or traditional prepaid SIM card, and explains how to install it without mistakes.
eSIM or prepaid SIM card: which to choose?
- Travel eSIM: bought online, installed via QR code or app, activated on arrival. Most often data only (no French number), but perfect for maps, bookings and messaging. It is the simplest option for a stay of a few days.
- Prepaid SIM card (physical): bought in a shop in France, it gives you a French number (+33) and allows calls and texts. You need to show ID and visit a shop: see our guide Prepaid SIM cards in France: prices and operators.
- Your operator’s roaming: if you live in the EU, your plan works in France at no extra cost (the European “roam like at home” regulation). Still check your data allowance.
What is an eSIM, and how does it work?
An eSIM is a SIM card built into the phone: you don’t swap it physically, you download an operator profile. In practice: you buy a plan online, you receive a QR code (or an activation in the app), you scan it from your phone, and the line is added alongside your usual SIM.
Dual SIM lets you keep your original number for calls and use the eSIM for French data, which is handy for keeping WhatsApp and your contacts.
On arrival, simply activate the eSIM line for the mobile network and let data go through it. Some plans only start when you first connect to a French network: read the conditions carefully when you buy.

Two quick checks: search for “eSIM” in your phone’s settings, and make sure it is not locked to an operator (a phone bought on a contract may be locked).
What coverage is there in Nice and France?
French mobile coverage is among the best in Europe: 4G everywhere and 5G in Nice and on the Côte d’Azur, via the Orange, SFR, Bouygues Telecom and Free networks. Travel eSIMs generally use one of these networks, with no notable difference in town.
Two useful caveats: in the hinterland (the Vésubie and Mercantour valleys), coverage can weaken in mountainous areas; and Monaco and Andorra are not part of the European Union: if your itinerary includes Monaco, check that your plan covers it.
How much data should I plan for a stay?
- 1 to 3 GB: maps, transport, bookings, messages. Enough for a weekend or a week if you use wifi;
- 5 to 10 GB: social media, shared photos, a few videos;
- Unlimited or 20 GB and more: remote working, video calls, hotspot for several devices.
Free wifi in Nice (airport, libraries, cafés) reduces your needs even further: see our article Free wifi in Nice.
How much does it cost?
Expect anything from a few euros for a small eSIM plan lasting a few days to around thirty euros for a generous one-month data plan. For comparison, a French prepaid SIM card costs €2.99 to €19.99 depending on the plan, plus the price of the card itself (€5 to €10 at the major operators). The eSIM offer comparison above gives concrete examples, updated by our partners.
How do I choose an eSIM offer?
Compare five criteria:
- Coverage: France only, Europe, or worldwide, depending on your itinerary;
- Volume and duration: a 3 GB/7-day plan is not suitable for a month of remote working;
- Hotspot sharing, useful if you travel with several devices;
- Calls: a data-only eSIM cannot make calls, so use WhatsApp, Signal or a VoIP app;
- Price and refund policy.
Activating your eSIM: step by step
- Install the profile before departure, on wifi, on an unlocked phone;
- Keep the QR code or a screenshot of it (some operators only display it once);
- On arrival in Nice, activate the eSIM line and choose it for mobile data;
- Keep your original SIM active so you can receive calls and texts on your usual number.
Frequently asked questions
Does the eSIM work as soon as I land at Nice airport?
Yes: an activated eSIM picks up the network as soon as you land. Some plans only start at first connection, so you do not use up any days before arriving.
Can I make calls with a travel eSIM?
A data-only eSIM does not support traditional phone calls. You can use WhatsApp, Signal, Messenger or a VoIP app instead. For a real French number (+33), you need a prepaid SIM card bought in France.
Can my phone keep its original number?
Yes, thanks to dual SIM: your usual card stays active for calls and texts, and the eSIM handles data. Beware of your operator’s roaming charges if you leave data running on your original line.
Do I need a separate eSIM for Monaco?
As Monaco is not in the EU, it depends on the plan: some include it, others charge non-EU roaming. Check the list of covered countries before buying if you plan an excursion.
Is an eSIM cheaper than a French prepaid SIM?
For a short stay with mainly data use, an eSIM is generally simpler and often cheaper, with no trip to a shop. For a long stay with calls in France, a prepaid card with a French number is still the better choice.
