Hi, Could someone give a brief explanation on how audio/voice works if a 4G module (with 2G capability and a PCM interface) can only register to a 4G network, due to the lack of a 2G signal. Will voice/audio still work or does it rely on the 2G network? Thanks.

Gary,

No I have tested with aHL7690 (LTE only) and was able to receive the SMS although I suspect it is carrier dependent.

Regards

Matt
