If an error occurs while you are processing a command by means of AT+C, the problem
may be located in the data or GSM section of the M1. For example, if a data connection
is set up, the phonebook cannot be accessed at the same time. Or is the problem in
the SIM card? Is it inserted or has the PIN been omitted? Extended error messages
help you isolate errors more easily. However, you must first enable these messages
from the PC using this command.
AT+CMEE - Report mobile equipment error
