(Telecompaper) South African operator Cell C will launch Wi-Fi Calling to its entire customer base on 01 October. This turns any Wi-Fi hotspot into a Cell C base station. Unlike VoIP services (app to app calling), customers do not have to download an application but simply enable the service via their phone settings on a supported Wi-Fi enabled handset. Customers need to ensure that the Wi-Fi Calling icon appears at the top of their phone screen when using the service. Cell-C's new service is powered by ICT group Atos's WiFi Calling platform, announced in February. The ICT company said that that Cell C is amongst the first operators to have launched its solution on such a wide scale.
