EHS5:
Without SIM PIN - returns "ERROR" prior to --enable; returns "+CME ERROR: 4" after --enable
With SIM PIN - returns "ERROR" prior to --enable/--pin [can't enable without PIN]; then returns "ERROR" after --pin, and then "+CME ERROR: 4" after also --enable.

BGS2: returns "+CME ERROR: 100" in all the above cases
