Updated June 2026. France has four network operators: Orange, SFR, Bouygues Telecom, and Free Mobile, each with cheaper online brands (Sosh, RED by SFR, B&You). The market runs 84.7 million mobile SIM cards (ARCEP, 31 March 2026), with MVNOs holding about 5.1% of the metropolitan parc, while fibre (FTTH) now makes up 82% of fixed broadband lines and reaches 94.2% of premises. On arrival, start with a forfait mobile sans engagement you can sign up for online, then add a home internet box over fibre (FTTH) once you have an address and a RIB. Keep your number with a RIO code.

France telecom at a glance (as of June 2026)
A snapshot of the French market from the official sources. Mobile figures exclude machine-to-machine (M2M) cards. The 5G figure is a usage measure (active SIMs on a 5G network), not a coverage percentage.

Who are the main operators?
France has four network operators that own their own mobile and fixed-line infrastructure: Orange, SFR, Bouygues Telecom, and Free Mobile. Each also runs a low-cost online sub-brand on the same network: Sosh (Orange), RED by SFR, and B&You (Bouygues). Free Mobile, part of the Iliad group, is already positioned as the low-cost challenger. These sub-brands sell online only, with no shop support, which is why they are cheaper.
The market is overseen by ARCEP, the French telecom regulator (arcep.fr), which sets the rules on coverage, number portability, and quality of service. All four networks offer broadly similar 4G and 5G coverage in cities, but rural performance varies, so an éligibilité (coverage) check for your address matters.
Curious which network performs best where you live? See our best mobile network guide, which leans on ARCEP coverage and quality data rather than marketing claims.
| Network operator (MNO) | Approx. share (2025) | Sub-brands |
|---|---|---|
| Orange | ~39% (approx.) | Sosh |
| Free Mobile (Iliad) | ~21% (approx.) | None (Free is itself the low-cost brand) |
| SFR | ~20% (approx.) | RED by SFR |
| Bouygues Telecom | ~14% (approx.) | B&You, La Poste Mobile |
How do you get a mobile line?
The fastest route on arrival is a forfait mobile sans engagement, a monthly plan with no contract lock-in that you can cancel anytime. The low-cost brands (Sosh, RED by SFR, B&You, Free Mobile) let you subscribe online with a passport or ID and an IBAN, then ship a SIM or activate an eSIM within days. For day one, a prepaid SIM from a supermarket or operator shop bridges the gap.
See our SIM cards guide for prepaid and forfait options, and our eSIM guide if your phone supports a digital SIM you can activate before you even land.
Mobile before box
Mobile vs home internet?
A forfait mobile covers your phone, while a box covers home internet. Each operator brands its box differently: Livebox (Orange), Freebox (Free), SFR Box, and Bbox (Bouygues). Most new connections use fibre (FTTH), fibre to the home, which is faster and more reliable than older ADSL copper lines. A box typically bundles a Wi-Fi router, a landline, and often a TV decoder.
Before subscribing, run an éligibilité check with your exact address to confirm fibre is available; coverage differs building by building. Installation may need a short technician visit, and you will provide a RIB for the monthly prélèvement (direct debit). Our home internet guide walks through choosing and ordering a box.
How does number portability (RIO) work?
A RIO(Relevé d'Identité Opérateur) is the code that lets you keep your phone number when changing operators. Call 3179 for free from the line you want to port and the system reads out (and texts) your RIO. Give it to your new operator when you subscribe, and it handles the transfer and closes your old line, usually within three working days, with no double billing. Portability is free. Any contract commitment is capped at 24 months, but most plans today are sans engagement, so switching is straightforward.
Inside the EU, EU roaming rules let you use your French forfait across the EU and EEA at no extra cost, subject to a fair-use data limit set by each operator. Use outside the EU is billed separately, so check your operator's terms before travelling. These consumer protections are backed by ARCEP, the Médiateur des communications électroniques for disputes, and the DGCCRF for unfair commercial practices.
