Use the below code to get the SIM card ID

TelephonyManager tm = (TelephonyManager) 
        getSystemService(Context.TELEPHONY_SERVICE);     
 String simID = tm.getSimSerialNumber();

Store the data in SharedPreferences and again use the above code to get the SIM card ID every time you open the app and check the new SIM card ID with that ID which is stored in the SharedPreferences. If the data is different, that means the SIM card is changed and you can process further according to your requirement.
