6.3 VoLTE Calls

The VoLTE service provides the highest quality calls via the LTE network. The service is available wherever there is an LTE signal.

Turn on the IMS function on the Network / VoLTE card to enable the VoLTE function in the device. Data is enabled by the device by default, use the Network / WWAN card to change the setting. Make sure that the Network technology value on the WWAN card is always LTE (i.e. connection to LTE network) for the VoLTE calls. VoLTE calls are also available with automatic network selection if an LTE network is available. This is how the VoLTE calls are set.
