There are three possible response of SAMBA:
+CGREG:0,1 means the SAMBA is successfully attached.
+CGREG:0,0 means the SAMBA is trying to attach.
+CGREG:0,2 has failed to attach and stopped trying to attach.
This occurs approx. within 1-3 min of powering up.
+CGREG:0,3 Registration denied. The GPRS service is disabled,
the MS is not allowed to attach for GPRS if
requested by the user.
+CGREG:0,4 unknown
+CGREG:0,5 Registered, roaming
Alternatively, the registration status can be retrieved using:
AT+CGATT?
There are two possible response of SAMBA:
+CGATT:1 means the MS is successfully attached.
+CGATT:0 means the MS is not attached, or has failed to attach.
This command is somewhat less accurate than AT+CGREG?.
If the SAMBA Modem is attached to the GPRS Network the user have

if everything is going smoothly the SAMBA modem within 2 or 3
seconds will be able to build a connection to the Internet.
