3.2.4.1   Call Barring Service status query 
 
• 
send command 
AT+CLCK=<fac>,2<cr> 
 
where:  
<fac> is the facility to be queried: 
AO - Barring All Outgoing Calls 
OI  - Barring Outgoing International Calls  
OX- Barring Outgoing International Calls except to Home Country  
AI  - Barring All Incoming Calls  
IR   - Barring Incoming Calls when Roaming outside the home country  
AB - All Barring services (applicable only for disabling command) 
AG - All Outgoing barring services (applicable only for disabling command)

• 
wait for response:
 
 
Response 
Reason 
Action 
+CLCK: 0 
facility is disabled 
calls are allowed 
+CLCK: 1 
facility is enabled 
calls are barred 
+CME ERROR: 4 
operation not supported, the 
service required is not available
Check command syntax and 
service code 
+CME ERROR: 30 
no network service 
Check for registration (see par. 
2.5.3.1) and signal strength. 
 
 
NOTE: 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's 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.
