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, SFR offers a wide range of services, from fibre broadband and TV packages to mobile plans and prepaid SIM cards. With over 27 million customers, SFR is a popular choice among both locals and expats settling in France.
SFR's offers are known for their strong network coverage and attractive bundles that combine Internet, French TV and mobile. Whether you're moving to France for work, studies or long-term residence, SFR can provide everything you need to get connected quickly and easily.
In 2011, SFR launched a low-cost brand, RED by SFR, offering no-contract mobile and internet plans (sans engagement).
SFR France offers include:
- ✓Fibre and ADSL broadband for homes and apartments;
- ✓Mobile plans with 4G and 5G coverage nationwide;
- ✓Prepaid SIM cards (no contract, ideal for short stays);
- ✓SFR TV and entertainment options, including over 200 channels;
- ✓International calling and roaming options across Europe.
SFR's website is mainly in French, but you can subscribe to SFR offers in English through partners like Selectra, which help expats compare deals and sign up with English-speaking support.
In August 2025, Altice France completed a debt restructuring plan validated by the Paris Commercial Court. Patrick Drahi retains 55% of Altice France, while a creditor consortium (BlackRock, Pimco, Fidelity) obtained 45% in exchange for approximately €6 billion in converted debt. No service changes affect SFR customers.

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.

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).
