Command
Possible response(s)
+CGREG=[<n>]
+CGREG?
+CGREG: <n>,<stat>[,<lac>,<ci>]
+CME ERROR: <err>
+CGREG=?
+CGREG: (list of supported <n>s)
Description
The set command controls the presentation of an unsolicited result code +CGREG: <stat> when <n>=1 and there is
a change in the MT's GPRS network registration status, or code +CGREG: <stat>[,<lac>,<ci>] when <n>=2
and there is a change of the network cell.
NOTE. If the GPRS MT also supports circuit mode services, the +CREG command and +CREG: result code
apply to the registration status and location information for those services.
The read command returns the status of result code presentation and an integer <stat> which shows whether the
network has currently indicated the registration of the MT. Location information elements <lac> and <ci> are
returned only when <n>=2 and MT is registered in the network.
