How to detect Network operators programmatically o

问题:

Is it possible to identify currently attached mobile network and network operators programmatically on Android? If it is possible please provide code samples

Thank you.

Try this,

// Get System TELEPHONY service reference
TelephonyManager tManager = (TelephonyManager) getBaseContext()
      .getSystemService(Context.TELEPHONY_SERVICE);

// Get carrier name (Network Operator Name)
String carrierName = tManager.getNetworkOperatorName();

// Get Phone model and manufacturer name
 String manufacturer = Build.MANUFACTURER;
 String model = Build.MODEL;

You can try this:

  public String getNetworkOperatorName(){
        TelephonyManager tm =
            (TelephonyManager)mCtx.getSystemService(Context.TELEPHONY_SERVICE);
        return(tm.getNetworkOperatorName());
    } 

You can use this for more methods

To get more details about networks:

// Get the connected network operator ID (MCC + MNC)
String networkOperatorId = telephonyManager.getNetworkOperator();

// Get the connected network operator name
String networkName = telephonyManager.getNetworkOperatorName();

// Get the type of network you are connected with 
int networkType = telephonyManager.getNetworkType();
switch (networkType) {
case (TelephonyManager.NETWORK_TYPE_1xRTT) :" Block of Code ":
break;
case (TelephonyManager.NETWORK_TYPE_CDMA) :"  Block of Code ":
break;
case (TelephonyManager.NETWORK_TYPE_EDGE) : "  Block of Code ":
break;
case (TelephonyManager.NETWORK_TYPE_EVDO_0) :"  Block of Code ":
break;

Never used it myself, but take a look at TelephonyManager->

// Get System TELEPHONY service reference
    TelephonyManager tManager = (TelephonyManager) getBaseContext()
          .getSystemService(Context.TELEPHONY_SERVICE);

    // Get Mobile No 

    String mPhoneNumber = tManager.getLine1Number();

    // Get carrier name (Network Operator Name)
    String carrierName = tManager.getNetworkOperatorName();

    // Get Phone model and manufacturer name
     String manufacturer = Build.MANUFACTURER;
     String model = Build.MODEL;

private static String getOutput(Context context, String methodName, int slotId) {
    TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    Class<?> telephonyClass;
    String reflectionMethod = null;
    String output = "";
    try {
        telephonyClass = Class.forName(telephony.getClass().getName());
        for (Method method : telephonyClass.getMethods()) {

            if (name.contains(methodName)) {
                Class<?>[] params = method.getParameterTypes();
                if (params.length == 1 && params[0].getName().equals("int")) {
                    reflectionMethod = name;
