OK
If error is related to ME functionality:
+CME ERROR: <err>
Parameter
The output contains 9 values from a maximum of 7 base stations. The first base
station is the serving cell.
Values for one base station in output order:
MCC Mobile country code, 3 decimal digits, e.g. 232
Value 000: not decoded
MNC Mobile network code, 2 decimal digits, e.g. 03
Value 00: not decoded
LAC Location area code, 4 hexadecimal digits, e.g. 3010
Value 0000: not decoded
cell Cell ID, 4 hexadecimal digits, e.g. 4EAF
Value 0000: not decoded
BSIC Base station identity code, 2 decimal digits, e.g. 32
chann ARFCN (Absolute Frequency Channel Number) of the BCCH
carrier, decimal, e.g. 82.
Value 0: not decoded. In this case, all remaining parameters related
to the same channel are neither decoded. For example, a non-
existing cell appears as follows: 000,00,0000,0000,00,0,0,0,0
RSSI Received signal level of the BCCH carrier, decimal value from
0 to 63.
The indicated value is composed of the measured value in dBm
plus an offset. This is in accordance with a formula specified in
3GPP TS 05.08.
C1 Coefficient for base station reselection, decimal, e.g. 30
C2 Coefficient for base station reselection, decimal, e.g. 30

Note
· In dedicated mode, the parameters C1 and C2 cannot be updated, and
therefore, should be ignored.
· To some extent, the cell monitoring commands AT^MONI, AT^MONP and
AT^SMONC cover the same parameters. The receiving level, for example,
can be queried with all three commands. Yet the resulting values may be
slightly different, even though obtained over a time period of a few seconds.
This is quite normal and nothing to worry about, as the cell information is
permanently updated.
