M1 announced the launch of Singapore’s first public native Voice over WiFi (VoWiFi) trial with full seamless mobility through the HetNet (Heterogeneous Network) technology.

M1 said that the WiFi Calling service enables the user to make data voice calls using the handset’s native dialler and offers convenient direct access to the device’s contacts list, without the user having to install or use a separate calling application. In addition, M1’s service will allow calls to and from fixed numbers unlike OTT (over-the-top) calling apps which only allow calls between handsets with the same calling software.

M1 WiFi Calling also supports two-way mobility between WiFi and mobile networks. This means that a voice call initiated on a WiFi network will not disconnect when the user moves to cellular network, and vice versa. In this way, customers will enjoy uninterrupted two-direction, high-definition voice calls across M1’s cellular and M1's carrier WiFi networks.
