Orange Belgium has launched Voice over WiFi and Voice over 4G. The launch, which Orange says is a first for Belgium, means customers will be able to make voice calls on Orange's WiFi, 2G, 3G or 4G networks. Voice over WiFi and Voice over 4G calls will be invoiced as normal voice calls.
VoWifi lets people call even when there is no mobile network available, at home or from public areas with Wi-Fi, in the basement or on a train. Users need only have a mobile post-paid subscription with Orange, a compatible device, a good Wi-Fi connection and VoWiFi technology enabled on their smartphone.
VoLTE allows voice calls directly on the 4G network. The technology enables calls in high definition, with a call set up of 2 seconds, against up to 10 seconds over 2G or 3G. Customers calling on Orange's 4G network will be able to multitask during their call, go on internet, or download content. To make a call over Orange's 4G network, users will need a mobile post-paid subscription with Orange, a compatible device, 4G coverage and activated VoLTE technology.
Orange customers with a Samsung Galaxy S7/S7 Edge device will be the first in Belgium to enjoy both technologies. The Samsung Galaxy S8/S8+ and Galaxy S9/S9+ will follow very soon. Customers with an iPhone (5S or more recent models) will benefit from VoWiFi first, with VoLTE to follow soon. Orange is also working closely with Huawei and other phone-makers to activate both technologies in the near future.
