Configures the GPRS network registration information. Depending on the <n> parameter value, a URC can be
issued:
• +CGREG: <stat> if <n>=1 and there is a change in the GPRS network registration status in GERAN/UTRAN
• +CGREG: <stat>[,<lac>,<ci>[,<AcT>,<rac>]] if <n>=2 and there is a change of the network cell in GERAN/
UTRAN
