User Manual

When a response +CREG: x,1 or +CREG: x,5 is received, then the device is ready to place
and receive a call or SMS. It is possible to jump directly to call setup procedures or SMS
sending procedures.
Once the mobile has registered on some network (or even if it has returned +CREG:x,3), it is
possible to query the mobile for network identifications, codes and names:
 send command AT+COPS=?<cr>
 wait for response in the format:
+COPS: : [list of supported (<stat>,long alphanumeric <oper>,short alphanumeric
<oper>,numeric <oper>,< AcT>)s]
[,,(list of supported <mode>s),(list of supported <format>s)]
where:
<stat> - operator availability
0 - unknown
1 - available
2 - current
3 - forbidden
<AcT> access technology selected:
0 GSM
2 UTRAN
Since with this command a network scan is done, this command may require some seconds
before the output is given.
For example:
command
AT+COPS=?<cr>
Answer:
+COPS: (2,"I WIND","WIND","22288",2),(1,"SI MOBITEL
GSM","","29341",0),(1,"Vodafone IT","OMNITEL","22210",2), (3,"I
TIM","TIM","22201",0),,(0-4),(0-2)
