eSIM in France: The Complete Guide for a First Visit

French data is priced upside down, and once that is visible the rest of the purchase gets easier. Five gigabytes that last thirty days start at $4.00. The cheapest five gigabytes that last seven days cost $7.99. A visitor staying a week pays double what a visitor staying a month pays for the same data.

The money sits in odd places. A gigabyte costs $0.30 on the cheapest plan, a 240GB bundle that lasts a full year, and $7.00 on the smallest trial size. One plan sits 23.3 times above another, one of the widest gaps on the shelf, so a careless buy costs more here than a traveller expects.

The cheap end is also the forgiving end: the 5GB band runs from $4.00 to $11.99 and the 20GB band from $9.00 to $35.00, which is nothing like the spreads in Britain or Canada.

Orange, SFR and Bouygues appear in every plan from every brand, so nothing about the network changes with the price.

Three things decide the purchase here: which window to buy, what a Sunday arrival does to the plan, and whether the identity rule that governs every French prepaid line reaches a profile issued abroad. The prices plan by plan are on the France comparison page, ranked one way by gigabyte and the other by day.

Should you buy a month for a short trip?

Yes, and the price ladder is the reason: the long window is priced for value, the short one for convenience.

Follow what the same five gigabytes cost as the window stretches. Three days, $6.00. A week, $7.99. Ten days, $9.00. Three weeks, $4.00. A month, $4.00. The price does not rise with time; it collapses. Short windows are sold to people in a hurry and long ones are priced for people who want something dependable.

Each row is the cheapest plan sold that carries at least five gigabytes for that window.

Two purchases follow. Buy the monthly plan even for a four-day trip, because it is cheaper than the weekly one. And skip the three-day and ten-day products entirely, since both are priced above a month.

The same inversion appears at ten gigabytes. A month of 10GB starts at $6.00, and the cheapest week at that size is $11.99. Needing more data for less time costs more here, which is the reverse of how most markets price.

Does the French ID law apply to an eSIM?

No, and that is the whole reason the profile is worth buying before the flight. Every French SIM has to be tied to a verified identity before it carries traffic, prepaid included. The rule comes from the 2016 law on organised crime and the 2017 decree that put it into practice, and the practical effect is that a line which is never identified is blocked and its credit disappears with it.

Buying is the easy part. A tabac or a supermarket will sell the card without asking for anything. Activation is where the document appears: a passport of any nationality, a European identity card or a residence permit, uploaded online or shown at a counter. The tourist products sold to visitors get a thirty-day window to complete it, and the ones that never do stop working.

A travel eSIM has no such step, because it is registered to the provider rather than to a person. Nothing is uploaded and no thirty-day clock starts. For an arrival at Charles de Gaulle on a Sunday evening, with the shops shut and the phone the only way to reach a hotel, that is the entire argument.

The trade is the number. A French number means the identity check, so the question is whether a number is worth a passport upload and a wait. For a visit the answer is usually no, because every one of those errands runs on data, and the gates read a contactless card or a phone wallet with no account behind it. Three cases change the answer, and they are a restaurant that books by telephone, a landlord or delivery that needs a local contact, and verification codes from French services. Keeping the home line alive covers the last one at no cost, which is what most visitors do.

The rule and the consumer rights that come with a French line are set out by ARCEP, the regulator, on its consumer pages.

What does a Paris week use?

Three gigabytes is enough for a city week of maps, metro times and a few photo uploads. Add a rented car, navigation running all day and a hotspot for a second phone and the same week passes 10GB.

The sizing advice in France is unusual, and it follows from the pricing. There is no reason to buy a seven-day plan at all. A plan for a month costs $4.00, which is less than the seven-day version, so the short window is the expensive choice whether the trip is short or not.

Anyone who expects to come back within a year can do better still: 24GB spread across twelve months starts at $9.00. That plan covers a week in Paris now and another week in the spring, and it ends the annual ritual of buying the same thing twice.

What do you check before you pay?

All ten brands reach all three French networks, so the purchase turns on the window, the payment and whether the product is French or European. The first section has already answered the window, which leaves two checks with real consequences: whether the plan is a France product rather than a regional bundle, because a bundle charges for countries the trip will not visit, and whether the payment method will clear, because the RER B ticket machines are where a phone without data stops being useful.

Installing takes one connection and about two minutes, and the connection is the part that has to be planned. The QR code or the provider’s app both need to reach the network while the profile downloads, so doing it at home is strictly better than doing it on a platform. The profile waits, dormant, until the line is switched on, so nothing is spent by installing a week early. Name the profile, and do not delete one to start over, because a deleted profile generally has to be reissued by the provider, which is a support conversation at the least convenient moment and a fee at some brands.

Two settings decide whether the phone will use it. The first is eSIM support, and the quickest test sits in the phone’s own settings: a handset that can hold a profile shows an EID on the same screen as the IMEI. Apple’s model list covers the models Apple sells and the compatibility check covers the rest, including the regional variants that shipped without one. The second is 4G calling. France still runs older networks, so a handset without VoLTE is not stranded here the way it is in Britain, but the setting is worth turning on anyway because it keeps calls on the faster network.

Buying more data mid-trip is where the window matters again. Because French windows reward length, the sensible second purchase is usually a longer plan rather than a bigger one, and a monthly plan bought in Paris often costs less than the weekly one anyone would buy in a panic. The timing rule catches people: a plan starts on the day of purchase rather than the day the previous one ends, so buying at the start of week two throws away the second week of the first plan. Profiles also share the phone’s slots and there are only a few of them, so starting with a monthly plan is the way to avoid ever needing that slot.

Will your card go through?

The card is rarely the problem. The bank is, and the trigger is a first payment to an unfamiliar merchant in another currency, made from an airport, at the point where a fraud model is most suspicious.

What reliably works: telling the bank in advance, approving the charge inside the banking app while it is pending, or paying through Apple Pay or Google Pay instead of typing the number. What reliably does not: retrying a declined card, because the merchant often locks for that card after two failures.

There is one French-specific trap worth naming. Some French banks block foreign-currency e-commerce by default and unblock it only after a call, which is a poor use of a Sunday evening before a Monday flight. Checking that the card has made an overseas purchase before is the cheapest test.

The brands price in US dollars. Conversion at the issuer’s rate is a rounding difference next to buying the wrong plan.

Can you force a French network when data stalls?

Yes, and it is the first thing to try when the phone shows bars and moves nothing.

Four national networks operate in France: Orange, SFR, Bouygues and Free. A travel profile is usually steered to one of them, and the steering is imperfect where two overlap, so the handset can sit on a network that is present and congested at the same time.

The switch lives in the mobile network settings. Turning automatic selection off brings up the list, and choosing by hand holds the choice. Orange reaches further into the countryside, which matters on a drive through Provence and rarely matters inside Paris.

Airplane mode for thirty seconds is the quicker first attempt, because it forces a fresh attach without changing a setting. Manual selection is the second attempt, once the first has produced nothing.

The failure that looks like a network fault and is not: the profile is installed but mobile data is still pointed at the home SIM. That shows the same bars and the same silence, and it is fixed in the data settings rather than in the network list.

A French plan that fails on all four networks is not a steering problem. At that point the answer is the seller rather than the settings.

What is closed on a Sunday in Paris?

Sunday is the awkward arrival in France, and the network is not the reason. Most shops are shut, the tabac that sells SIM cards is shut, and an airport counter may be shut as well, which leaves the phone as the only working tool between the plane and a hotel door.

The RER B connects both terminals to the centre in roughly thirty-five minutes, and the airport ride costs €13 to €14, priced separately from the €2.55 city ticket. Contactless bank cards and phone wallets have worked at most metro and RER gates since 2024, so a phone with a working wallet is also a working ticket, but only if it has a working connection to top the wallet up.

Turn the eSIM on in the terminal rather than on the platform. On Orange, SFR or Bouygues the connection usually comes up inside a minute, and the home line keeps its number for calls and codes.

Does a French plan reach Geneva?

No, and the border is the point. A France-only plan names France and drops the session at the Swiss border, so the train from Paris to Geneva arrives connected to nothing.

Switzerland compounds it by sitting outside the European roaming area. A European line that roamed free across France reverts to a chargeable rate the moment it registers on a Swiss network, and most European bundles are built on the EEA list and omit Switzerland deliberately.

Two fixes exist and they are not equal. A European bundle whose published list names Switzerland is the tidier answer, and those lists are worth reading before paying because the marketing does not settle it. A second profile for the Swiss leg costs more in total but removes the ambiguity. The Switzerland table prices that leg, and the Europe coverage breakdown compares the lists side by side.

When is a home SIM already enough?

It depends entirely on where the home SIM was issued, and for two travellers on the same flight the answer is opposite.

A line from the European Union or the wider European Economic Area roams in France at domestic prices as a matter of right, and that arrangement runs until 30 June 2032. For those travellers a French data plan is a second purchase they do not need, unless the trip lasts long enough for the daily allowance to run short.

A British, American or Australian line has no such right. Since the UK left the European roaming area its carriers set their own charges, and a US day pass typically costs more than a short-break French plan. For that group the comparison is not close, with the cheapest French gigabyte at $0.30 and a month of 5GB at $4.00.

The France comparison page ranks all 203 plans by cost per gigabyte and by cost per day, and the price index is where a French year plan holding a very low daily rate is visible against everything else.
