Hi,
I have two modules:
EP06-E, firmware EP06ELAR03A08M4G
EM12-G, firmware EM12GPAR01A21M4G
On both, AT+CIREG? returns ERROR, and incoming calls never show up.
Is there a firmware version with VoLTE/IMS support for these modules? If yes, how can I get it and install it?
If it’s not possible for these modules - is there recommended module with this feature?
