Does the datasheet help? https://www.ktron.in/wp-content/uploads/2023/03/A76XX-Series_AT_Command_Manual_V1.06-4.pdf

I have read the data sheet completely.

my issue is the IMS APN which the 7680 uses for Volte connection.

CID1 IPV4V6 Jionet
CID8 IPV4V6 ims

cid8 comes automatically for Volte.

but the PDP connects then disconnects this goes on forever for CID8

if i do this

CID1 IPV4V6 "ims"
CID8 IPV4V6 "ims.mnc864.mcc405.gprs"

then the PDP CID8 latches on but no registration

cheers
