Orange France is threatening to cut mobile network access for customers of roaming partner Free Mobile at peak times to avoid network congestion. Low-cost operator Free Mobile launched France’s fourth cellular network in January and has signed a wholesale roaming deal with Orange to allow it to offer nationwide coverage while it deploys its own infrastructure. But Iliad subsidiary Free has been criticised for sending too much traffic onto the Orange network at peak times in the early evening. Orange now says that it will act to preserve quality of service for its own subscribers, so may have to cut roaming access for Free Mobile customers if the network becomes overly congested. It has been claimed that Free Mobile has attracted more than 2.2 million customers in just over two months since its launch, although official figures have not yet been released.
