Notes
• If the MT is in dedicated mode, write command returns with "+CME ERROR: operation temporary not
allowed".
• When the module is GPRS attached and a PLMN reselection occurs to a non-GPRS capable 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
<state>=1.
