Call over WiFi and 4G anywhere


With VoWiFi (Voice over WiFi) and VoLTE (Voice over 4G/LTE) Orange is the first operator in Belgium to offer incoming and outgoing calls over WiFi as well as 4G. As a result you will be reachable anywhere, at no extra charge and without the need of an extra app.

With VoWiFi and VoLTE you make calls with your mobile over WiFi or 4G. Moreover, Orange is the only operator in Belgium to offer HD Voice via all network technologies (2G, 3G, 4G and VoWiFi), giving you crystal clear sound quality.

At the moment of launch VoWiFi and VoLTE support the Samsung Galaxy S7/S7 Edge (for VoWiFi and VoLTE) and the iPhone 5S up to the iPhone X (for VoWiFi).The number of supported devices will increase steadily, as we certify these devices to guarantee an optimum user experience.


VoWiFi offers the advantage that you can call and be called at locations where the mobile network does not offer (sufficient) coverage, such as inside a well-insulated building. VoWiFi can be used wherever WiFi is available, including trains, the dentist’s waiting room or a hotel. If you move to an area without WiFi coverage during your call, then the conversation switches seamlessly to 4G (currently supported on a Samsung Galaxy S7/S7 Edge).


Did you know that back in the day only surfing was possible via 4G? VoLTE offers the advantage of an HD conversation over the 4G network, while surfing at 4G speed. Indoor coverage has also improved compared to the past, when your calls routinely involved the 2G or 3G network.                    

Set as standard

Both technologies are only available in Belgium. VoWiFi and VoLTE are set as standard for all B2B customers whose tariff plan includes 4G.

Fast 4G network

As a provider of convergent telecom services we naturally attach a great deal of importance to an excellent mobile network. According to the independent study “State of Mobile Networks: Belgium” conducted by OpenSignal1in March 2018, we have the fastest 4G network in Belgium as well as the best 4G coverage.
