Hi I am developing an application that changes a button according to the SIM STATE
I am using 1 for NO SIM and 5 for SIM READY
In few case I have no service for example, if the SIM card is an international card , It doesn't work in other places. What is the SIM State for this type of condition.
Please suggest how to check when there is a SIM card but no service. Thanks!

// do something
break;
