On a related note, since ModemManager already uses AT+CRSM to read
ICCID and operator name/ID, I wonder if it makes sense to
"AT+CRSM=176,28423,0,0,9" instead of AT+CIMI for reading IMSI, or use
it as a fallback solution if AT+CIMI fails or is not supported by a
modem.
At least on one modem I have, "AT+CRSM=176,28423,0,0,9" is far more
reliable than AT+CIMI (which may be an issue in the modem firmware).
