able PLMN is available.

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

<stat>=1 or <stat>=5.
