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.
