Android access to mobile phone SIM card carrier information method _android

This example describes Android's approach to acquiring information about mobile phone SIM card operators, which is of practical value for Android programming. Share for everyone to use for reference. The specific methods are as follows:

The main functional code is as follows:

/**
 * Get SIM card operator
 * * 
 @param context
 * @return
/public static String Getoperators Context) {
 Telephonymanager TM = (telephonymanager) context
  . Getsystemservice (context.telephony_service);
 String operator = null;
 String IMSI = Tm.getsubscriberid ();
 if (IMSI = null | | Imsi.equals ("")) {return
 operator
 }
 if (Imsi.startswith ("46000") | | Imsi.startswith ("46002")) {
 operator = "Chinese mobile";
 } else if (Imsi.startswith ("46001")) {
 operator = "China Unicom";
 Else if (Imsi.startswith ("46003")) {
 operator = "China Telecom";
 }
 return operator;
}

/**
 * Mobile phone model
 * 
 * @return
 /public
static String Getphonemodel () {
 return Android.os.Build.MODEL;
}

/**
 * System version
 * 
 * @return
/public static String Getsystemversion () {
 return Android.os.Build.VERSION.RELEASE;
}

The permission code is as follows:

<uses-permission android:name= "Android.permission.READ_PHONE_STATE"/>
