Result and Error Codes 6
Result codes from call connections
During on-line operation of the telephone, result codes inform you about the progress of call connections:
Format of the result codes
The result codes described above are in verbose format. You can command the built-in modem to display result
codes in verbose or numeric format or you can switch them off completely.
To switch between verbose and numeric format, please refer to the use of the ATV command on page 26.
To switch the display of result codes on or off, please refer to the use of the ATQ command on page 25.
The +CME ERROR result codes indicate an error relating to the functionality of the built-in modem or Mobile
Phone and replaces the final result code ERROR when enabled by the AT+CMEE command.
