register to. The ME is in GMM state GMM-DEREGISTERED or GMM-REGIS-
TERED-INITIATED. The GPRS service is enabled, but an allowable PLMN is
currently not available. The ME will start a GPRS attach as soon as an allow-
able PLMN is available.

is disabled, the ME is not allowed to attach to GPRS if requested by the user.

5 Registered, roaming. The ME is in GMM state GMM-REGISTERED or GMM-
ROUTING-AREA-UPDATING-INITIATED on a visited PLMN.
Note
• When the module is GPRS attached and a PLMN reselection occurs to a non-GPRS network or to a network
where the SIM is not subscribed to for using GPRS, the resulting GMM (GPRS mobility management) state
according to GSM 24.008 is REGISTERED/NO CELL, meaning that the read command will still show
=1 or =5.
