If you work in Switzerland or go there often, take the eSIM of a French plan that includes Switzerland, such as Flytel plans, from €14.99 a month. You keep the same number and the same plan on both sides of the border. For a few days’ holiday, a travel eSIM is enough.
Can I use a French eSIM in Switzerland?
Yes. A French eSIM works in Switzerland just like a physical SIM card: through roaming, on a Swiss operator’s network. Apple says so for the iPhone (eSIM and travelling abroad). An eSIM is a digital SIM card, built into the phone: nothing to insert, you install it with a code. What you pay there therefore depends on the plan, not on the SIM type. With Flytel, you get 20 GB to 50 GB of mobile data in Switzerland, depending on the plan. Two conditions: a phone that supports eSIM (check yours by typing its model (in French)), and data roaming turned on.
Which eSIM for working in Switzerland when you live in France?
To work in Switzerland while living in France, take the eSIM of a French plan that includes Switzerland, such as Flytel, the mobile operator for Swiss cross-border commuters: your number stays French, reachable on both sides, and you keep the same plan as you cross the border every day. A travel eSIM covers a few days, most often without a number. Both Flytel plans, with no commitment and from €14.99 a month, include Switzerland: unlimited calls, texts and MMS from and to Switzerland, to Swiss landlines and mobiles alike. Mobile data in Switzerland is counted separately from your France allowance: 20 GB for France and 20 GB for Switzerland and Europe with the Essentiel plan, 100 GB and 50 GB with the Confort plan. What you use in Switzerland doesn’t touch your data volume in France.
Three points vary from one plan to another, to check before you choose: calls made from Switzerland, calls to a Swiss mobile from France, and the volume of mobile data you can use there. For what each operator includes, plan by plan: what “Switzerland included” really covers (in French).
eSIM and number porting: what should a cross-border commuter choose?
Choose a French plan that includes Switzerland, as an eSIM, and keep your number. With Flytel, you give your RIO code when you order, the transfer takes place three working days later at the earliest, and the eSIM arrives by email the day before the transfer. Your old plan ends by itself that day: you have nothing to cancel, and you can get everything ready before your first working day in Switzerland. Activation costs €5, paid once. The RIO code, the calendar and transfer day: keep your number.
Why Switzerland is a special case
Switzerland is not in the European Union. In Italy or Spain, your French operator must charge you French prices. In Switzerland, this rule doesn’t apply: the European Commission makes this clear, and Arcep, the French telecoms regulator, points out that outside the European Economic Area, operators set their prices freely. Including Switzerland is therefore each operator’s choice, plan by plan.
Two protections apply all the same: a message about prices when you cross the border, and a spending cap on mobile data, set by default at €50 excluding VAT a month outside the Union. For the details of the three possible cases: your phone in Switzerland when you live in France (in French).
First, look at what your plan already includes
Of the 33 French plans or groups of plans surveyed between 18 and 23 October 2026, 24 include mobile data in Switzerland. What varies from one plan to another: calls from France to Switzerland, calls made from Switzerland, and the volume you can use there. The contracts of the major operators, plan by plan (pages in French): Free in Switzerland, SFR in Switzerland, RED by SFR in Switzerland, Bouygues Telecom in Switzerland, Orange in Switzerland and Sosh in Switzerland. If yours is enough, you don’t need anything else.
A travel eSIM, for a few days
These eSIMs are sold by global providers. They are prepaid data plans, often without a phone number, as Apple describes in its help pages. They install alongside your usual SIM card.
Two things to know. If you keep your French plan active at the same time, your number stays reachable, and that plan can still be charged abroad. And without a number, your calls go through apps. For a weekend or a week of skiing, it is often the simplest option.
A French plan with Switzerland included, as an eSIM
Do you cross the border often? A plan that includes Switzerland saves you from changing SIM card. Flytel plans include calls, texts and MMS from and to Switzerland, and 20 GB to 50 GB of mobile data for Switzerland, Europe, Andorra and the French overseas departments. On the Orange network, with no commitment, from €14.99 a month.
As an eSIM, the plan is delivered by email, once your order is approved, with a one-off €5 activation fee. On a compatible phone, it installs alongside your current SIM card, with a French number: a new one, or yours if you choose to keep your number. The plans are on the plans page, and step-by-step installation on install your eSIM. Before comparing with another offer: what “Switzerland included” really covers (in French).
SIM card for Switzerland: what if you don’t use an eSIM?
The same plan exists as a physical SIM card, sent by post for €10, paid once: it goes into a phone that doesn’t support eSIM, with the same calls and the same mobile data in Switzerland. You choose it when you order, instead of the eSIM.
Which one to choose
| Your situation | The option that suits | What to know |
|---|---|---|
| A few days’ holiday | A travel eSIM | Often without a number; your French plan, if it stays active, may be charged |
| Frequent trips, or work in Switzerland | A French plan that includes Switzerland | Check calls made from Switzerland and the volume available there |
Check that your phone supports eSIM
- iPhone: XS, XR and later models. The EID, the eSIM identifier, is in Settings, General, About. In the same place, “No SIM restrictions” next to the lock setting (“Carrier Lock” or “Network Provider Lock”, depending on the language) means the phone is unlocked.
- Google Pixel: the EID is in Settings, About phone, SIM status. The phone must be unlocked to accept another operator.
- Other Android phones: look for “eSIM” or “EID” in the settings, and see the virtual SIM card guide (in French).
Near the border, when the phone picks up a Swiss network
Your phone takes the network with the strongest signal. Near the border, it can connect to a Swiss mast while you are still in France. With a plan that charges for Switzerland, you then pay as if you were abroad, warns the Institut national de la consommation, the French national consumer institute. With Flytel, a phone that picks up a Swiss network stays within its plan: calls and texts are included, and mobile data is taken from the Switzerland and Europe allowance, 20 GB or 50 GB depending on the plan. At home, get back on the French network, so that your data is taken from your volume in France: turn on aeroplane mode for about ten seconds, then restart the phone and check that network selection is set to automatic. Choosing the network by hand is only a last resort. It is all explained in the guide to the network at the border.
In an emergency
112 works in Switzerland, including from a foreign SIM card or a prepaid SIM card with no credit, according to the portal of the Swiss Confederation. The other Swiss numbers are in the emergency numbers guide (in French).

Frequently asked questions
Yes. A French eSIM works in Switzerland just like a physical SIM card, through roaming, on a Swiss operator’s network. What you pay there depends on your plan, not on the SIM type: with Flytel, you get 20 GB to 50 GB of mobile data in Switzerland, depending on the plan.
Yes, through roaming, unless its contract blocks it. What it includes there depends on the operator and the plan. Switzerland is not in the European Union: the rules that make operators charge French prices don’t apply there, and each operator decides whether to include it, and at what price.
Not always. Many are prepaid data plans, often without a number: you then call through apps, or with your usual SIM card kept active alongside. The eSIM of a Flytel plan, on the other hand, has a French number, with unlimited calls, texts and MMS from and to Switzerland.
The eSIM of a French plan that includes Switzerland, such as Flytel, the mobile operator for Swiss cross-border commuters: one plan on both sides of the border, without changing SIM card at every crossing. Flytel plans include unlimited calls, texts and MMS from and to Switzerland, and 20 GB to 50 GB of mobile data for Switzerland, Europe, Andorra and the French overseas departments, from €14.99 a month.
