SFR: Frequently Asked Questions

What is SFR?

SFR is one of France's four main network operators, currently owned by Altice. Orange, Bouygues Telecom and Free signed the takeover of SFR in June 2026, with no client impact expected before the second half of 2027 (as of October 2026). SFR offers mobile forfaits, home internet boxes, and fibre.

Can I refuse an SFR price increase?

Yes. When SFR raised existing plans by €0.99 to €4.99 a month in October 2026, customers could refuse the change in their espace client and keep the old price, or cancel without fees within 4 months under article L224-33 of the Code de la consommation.

What is the difference between SFR and RED by SFR?

RED by SFR is SFR's no-commitment, online-only discount brand. RED runs on the same SFR network but is cheaper and has no in-store service.

Is SFR sans engagement?

SFR sells both committed and no-commitment plans. SFR's RED brand is fully sans engagement, meaning you can cancel any month.
