Are you looking forward to getting your hands on a new LG Nexus 4 from T-Mobile? If so, you should be aware of one feature the new smartphone will not have – WiFi calling. T-Mobile confirmed this would be the case after many potential buyers started asking questions about the feature. WiFi calling does require a specific app or code to be enabled and is usually inserted by the carriers. Considering the Nexus 4 is produced by LG for Google, it should probably not be surprising that T-Mobile was not able to get carrier specific features included on the devices.
