+CME ERROR: 30
no network service
Check for registration (see par.
4.4.3.1) and signal strength.
The call barring service is handled by the network, hence all the relative commands issue a
network request and it may take several seconds to have the response from the network.
Furthermore all the Barring service commands must be issued when the mobile is registered
on some network, else an error code is returned (no network service ).
For example:
1- Let us assume you want to check whether the incoming calls when roaming outside Home
Country are barred or not:
command
AT+CLCK=IR,2<cr>
response
+CLCK: 0
In this case, the incoming (received) calls ARE NOT BARRED when in Roaming outside the
Home Country.
2- Let us assume you want to check whether the Outgoing (originated) international calls are
barred or not:
command
AT+CLCK=OI,2<cr>
response:
+CLCK: 1
In this case, the outgoing international calls ARE BARRED.
 send command AT+CLCK=AI,<en>,<pwd><cr>
where:
<en> is the operation selected:
0 - Call Barring Disable (Unbarring)
1 - Call Barring Enable (Barring)
<pwd> is the network password required to change facility status
 wait for response:
