Began as a mobile carrier in 1987. Part of the Altice group since the 2014 merger with Numericable. Fixed copper and fibre networks originate to the absorptions of Louis Dreyfus Networks and Neuf.

Provides IPv6 on current service offerings, but also has legacy services (ADSL, HFC) still active without IPv6 support. Legacy services are due to be retired in the near future.
