SFR provides its more than 20 million* customers and foreign visitors passing through France with the best mobile telephony network in terms of coverage and connection speeds. About 87 % of the population covered by 3G+.

SFR’s performance is above all the result of its major programme of network investments. This has meant optimizing the quality and scope of coverage, both for GSM/GPRS and UMTS/HSDPA (for 3G/3G+). 

1.3 billion euros was invested in 2008 alone in the development of networks and information systems (facilities and equipment of access).
