About SFR in France

SFR (Société française du radiotéléphone) was created in 1987 by the Compagnie Générale des Eaux (which later became known as Vivendi) and soon became a major actor in the French mobile phone market. The company entered the landline telephone market when it deregulated in 1997 and has been offering internet plans since 2007. In 2014 SFR was bought by cable operator and telecommunications services company Numericable, which led to the creation of the Numericable-SFR group owned by Altice. Finally, in April 2016, the Numericable-SFR group disappeared uperating now under the SFR Group.

SFR offers include Internet plans, mobile phone plans, prepaid SIM cards, as well as phone and internet bundles + the option of Television or SFR TV.

In 2011 SFR launched a low-cost brand, RED by SFR, through which it offers no-contract mobile phone and internet plans (sans engagement).

  • SFR is a key player in the French telecoms market (figures as of 2021)
  • More than 10.9 billion € of turnover declared in 2020
  • 25 million subscribers
  • First telecommunications operator to offer 3G, 4G, and 5G in France
  • SFR 4G network covers 99.7% of the population in France
  • Launched 5G in Nice, the first French city covered by 5G in November 2020
  • SFR Fibre Optic coverage for more than 21 million homes

SFR Internet Network Coverage

SFR offers broadband internet access via ADSL over a large part of the country. The shortest lines (less than 1 km) may also be eligible for SFR VDSL or VDSL2, changes to ADSL. In VDSL2, the downstream speed can theoretically reach 70Mbits/s against 8Mbits/s for the upstream speed.

What is the difference between SFR (FTTH) and (FTTB) fibre offers?

SFR has developed its own fibre optic (FTTH) network. In June 2020, more than 16 million homes were covered by very high speed (FTTH and FTTB) from SFR in France.

FTTH offers (Fiber Box), deliver the fastest speeds among all the technologies deployed by SFR. However, the majority of very high speed SFR customers are not connected to Fibre Optic technology but to Fibre Coaxial or cable offers (FTTB). The FTTB network is none other than the vast network of the former cable operator Numericable. After the merger between Numericable and SFR, SFR took over this network to deploy very high speed offers.

In FTTH, the fibre optic line does not reach the interior of the property but stops at an optical node at the exterior of the building or street. The last meters of connection are made using a coaxial cable, which explains the speeds slightly lower than those of FTTH. The SFR FTTB offer is grouped together under the name Box THD (for Très Haut Débit or Very High Speed).

SFR France Mobile Network Coverage

SFR has a low cost French SIM card offer

According to the most recent surveys done by the French telecommunications regulator ARCEP, SFR's network coverage is more or less the same as other French Telecoms companies for 2G, 3G, and 4G coverage (SFR covers 99.2% of the population for 2G, 97% of the population for 3G, and 99.7% of the population for 4G in 2021).

SFR's service quality is relatively strong, slightly behind Orange but comparable to Bouygues Telecom and ahead of Free Mobile. Since 2019, the deployment of the SFR 5G mobile network has been underway in Metropolitan France, the first of which has included service rollouts at Nice in 2020, Nantes and Paris in 2021, with sites at Montpellier, Bordeaux, Marseille and wider Ile-de-France to follow.

SFR 4G Box Coverage

As part of the New Deal mobile degree published in 2019, SFR and other French telecom operators must provide a 4G internet service (Fixed 4G) or 4G box offer in government-identified geographic areas which do not yet have access to satisfactory fixed Internet offers (ADSL or fibre optic), and formerly satellite internet may have been the only available option. 4G box offers, subject to 4G coverage and capacity of the mobile network, now make it possible to quickly equip households with high-speed broadband in these locations.

In 2020, Arcep found that 4G box services covered approximately 24 million premises across France and that for around 4 million of them, fixed 4G was the best internet access technology in terms of maximum speeds. Additionally, SFR has obligations to extend their 4G box coverage in the areas covered by its 4G mobile network and deploy 500 new sites in these government-identified zones.

SFR Mobile Plans

New SFR Mobile offers in France

SFR offers a wide range of mobile phone plans, organized into two categories (4G and 5G). These plans give you the option to purchase the SIM card only, or select a new phone to go with the contract.

SFR's 2h 100Mb basic SIM only mobile plan is ideal for customers looking to have a small amount of calls and data per month.
