Siemens MC55 AT manual Stat=1 or stat=5

2	Not registered, but ME is currently trying to attach or searching an operator to
	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.
3	Registration denied. The ME is in GMM state GMM-NULL. The GPRS service
	is disabled, the ME is not allowed to attach to GPRS if requested by the user.
4	Unknown
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.
