Hi,

Sorry for sharing all the details including syslogs. I am not getting any
clue, where I am making mistake. Could anyone please point me, thanks a
lot. Subbu


1. Antenna Signal Quality is giving an error (could this be a cause?)

AT+CSQ

ERROR


2. After setting APN, qmi-network start as well mmcli (given next)

3. modemmanager output. (I read somewhere pin2 lock can be ignored)
