It is hard to tell from your log what is going on. Is your oFono
modified in some way? The AT command logging should print commands
sent, echo (if any) and command responses. I'm not seeing that here.
Do you get a response to the last CRSM command sent? If not, then
likely the modem crashed. The two CRSM commands you see above are
querying EFad and EFphase. Right after there should be some more EFs
being read followed by reading of the IMSI (+CIMI)

Who knows.

It just means that the sim atom driver does not implement this
functionality. It should probably be changed from a warning to a debug
message.

Impossible to tell without a log.
