Free Mobile (Iliad) and Orange has signed a national roaming agreement on 2 March 2011 for their respective 2G networks in France.
The agreement also extends to cover Iliad and Orange 3G networks.
Orange said that the agreement will take effect once Free Mobile has deployed a network that offers coverage for 25% of the French population.
In addition, under the terms of its licence, Free Mobile has committed to deploy a network that offers coverage to at least 90% of the population by 2018.
