SFR (an orphan acronym of Société Française du Radiotéléphone ) is a French telecommunications company. It provides services for mobile phone, landline, internet, IP television and mobile internet to consumers and businesses. As of 2012, it has 21 million customers, and provides 5 million households with high-speed internet access. It also offers services on the island of Réunion through SRR (Société Réunionnaise du Radiotéléphone) although the company is branded as SFR Réunion. SFR also has operations in Mayotte.
SFR is owned by Numericable and French conglomerate Vivendi. The SFR mobile phone network infrastructure was built by Vodafone, who previously had a 44% share in SFR until April 2011 when it sold the entire share back to Vivendi. However, SFR is still the partner network of Vodafone in France. 
Vivendi announced sometime about March 2014 that it planned to sell its SFR division. On 14 March it announced that it would enter exclusive negotiations with Altice/Numericable, to the exclusion of Bouygues and Free. Arnaud Montebourg, the French Minister for Industrial Renewal, provoked a storm when he stated that the Numericable-SFR deal was a certainty; Free lost 7.5% of its market value on that day.
