Since 1987
Founded
SFR (Société Française du Radiotéléphone) is one of the main Internet and mobile providers in France, founded in 1987 and now owned by Altice France. It offers fibre broadband, mobile plans, TV packages and prepaid SIM cards, all on France's second-largest network. In 2011, SFR launched a low-cost sub-brand, RED by SFR, with no-contract mobile and internet plans (sans engagement).
SFR France offers include fibre and ADSL broadband, mobile plans with nationwide 4G/5G, prepaid SIM cards, SFR TV (200+ channels), and EU roaming. Customer base figures are drawn from SFR's own published data; network coverage figures are detailed with their source further down this page.
SFR is a partner of Selectra: our advisors can compare SFR's plans against the market and help you subscribe directly, in English, free of charge. SFR's own website is mainly in French.
Bouygues Telecom, Orange and Free-iliad signed a memorandum of understanding in June 2026 to acquire SFR from Altice for approximately €20.35 billion. Definitive legal agreements are expected in the second half of 2026, with closing possibly in the second half of 2027 at the earliest — the deal still requires antitrust clearance from the European Commission, and nothing is final at this stage. See Orange's official press release. No immediate service changes affect existing SFR customers.

SFR Internet & mobile coverage in France
SFR's 4G network covers over 99% of the French population and 5G is live in most major cities and many mid-sized towns. Fibre (FTTH) reaches 85% of households, with ongoing deployment in smaller towns and rural areas. SFR coverage is comparable to Orange and Bouygues Telecom, and ahead of Free Mobile. Coverage figures are consistent with data published by ARCEP, France's telecom regulator, which tracks network deployment nationwide.

RED by SFR & other operators on the SFR network
Several operators use SFR's 4G/5G infrastructure, offering similar coverage at lower prices or with more flexible terms. SFR's own no-contract sub-brand is RED by SFR, which runs on the exact same network at reduced prices.
RED by SFR: the no-contract alternative
If you like the SFR network but prefer a simpler and cheaper plan, RED by SFR is the natural choice. Fully owned by SFR, RED runs on the same 4G/5G infrastructure but with no-contract offers, lower monthly prices, and fully online management — ideal for expats who want flexibility without giving up network quality.
Other MVNOs on the SFR network
Several other MVNOs also use SFR's infrastructure, offering the same coverage at lower or more flexible prices.
SFR Internet + mobile bundles: what discounts are available?
SFR makes it easy to combine your home Internet and mobile plans under one account. Choose any SFR Fibre or ADSL Box and pair it with one or more SFR mobile plans — discounts are automatically applied once both services are active.

SFR customer service in English
Yes, English-speaking help for SFR is available: Selectra's independent advisors guide you through comparing SFR plans and subscribing, entirely in English and free of charge, on +33 9 77 55 72 27 (Mon–Fri 8am–9pm · Sat 9am–7pm · Sun 9am–5pm). SFR's own customer service number, 1023, is French-only.
SFR does not have a dedicated English-speaking helpline of its own — customer service on 1023 and through the SFR & Moi app and website is handled entirely in French, with no official English-language option and wait times that can be long at peak hours. Selectra is an independent service, not affiliated with or operated by SFR.

5 plans analysed
A complete range — strong network, average customer support
SFR is France's second-largest operator with one of the best network footprints. The range covers all needs and RED by SFR offers genuine no-contract flexibility. Customer service satisfaction is a known weak point — plan subscriptions are straightforward, but getting help after signing up can be frustrating for non-French speakers.
What we love
- France's second-largest network — 99% 4G coverage nationwide.
- RED by SFR offers genuine value with no commitment.
- Complete range: fibre, mobile, TV, prepaid.
- 5G included on all recent mobile plans.
Keep in mind
- Customer service is French-only — no English helpline.
- Setup fees of €49 apply on most SFR Box plans.
- Prices have increased across the range in recent years.
- Ongoing ownership uncertainty (Altice restructuring).
What customers actually say
SFR's Trustpilot profile is almost entirely one-sided — among the lowest scores of any major French operator. That extreme split deserves context before drawing conclusions:
Trustpilot star split, August 2026
👍 Praised most
👎 Criticised most
“Five different advisors for one cancellation request, 20 minutes on hold each time, and contradictory information from every one of them.”
Anonymous · Aug 2026
“I understood from an SFR advisor that I should wait until 11 August to cancel. When I actually cancelled, I was then told the request needed to be made about 10 days earlier, and an extra month might get billed.”
Marie · 10 Aug 2026
Read this split with caution. Quotes above show their publication month as shown on Trustpilot; a precise date of experience isn't exposed by the platform for translated reviews, so none is invented here. Customers are far more likely to leave a review after a bad experience than a good one — a well-documented bias on every review platform, not specific to SFR. Still, a 91% 1-star share is unusually high even accounting for that bias, and SFR's profile shows no recent history of soliciting reviews, which tends to concentrate the sample toward complaints even further. Billing disputes and contract-renewal complaints recur often enough to treat as a genuine pattern, not just noise.
