How to tell if 'Mobile Network Data' is enabled or disabled (even when connected by WiFi)?

The following code will tell you if "mobile data" is enabled or not, regardless of whether or not there is a mobile data connection active at the moment or whether or not wifi is enabled/active or not. This code only works on Android 2.3 (Gingerbread) and later. Actually this code also works on earlier versions of Android as well ;-)

    boolean mobileDataEnabled = false; // Assume disabled
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    try {
        Class cmClass = Class.forName(cm.getClass().getName());
        Method method = cmClass.getDeclaredMethod("getMobileDataEnabled");
        method.setAccessible(true); // Make the method callable
        // get the setting for "mobile data"
        mobileDataEnabled = (Boolean)method.invoke(cm);
    } catch (Exception e) {
        // Some problem accessible private API
        // TODO do whatever error handling you want here
    }

Note: you will need to have permission android.permission.ACCESS_NETWORK_STATE to be able to use this code.

I've upgraded Allesio's answer. Settings.Secure's mobile_data int has moved to Settings.Global since 4.2.2.

Try This code when you want to know if mobile network is enabled even when wifi is enabled and connected.

Updated to check if SIM Card is available. Thanks for pointing out murat.

boolean mobileYN = false;

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (tm.getSimState() == TelephonyManager.SIM_STATE_READY) {
    if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN_MR1)
    {
        mobileYN = Settings.Global.getInt(context.getContentResolver(), "mobile_data", 1) == 1;
    }
    else{
        mobileYN = Settings.Secure.getInt(context.getContentResolver(), "mobile_data", 1) == 1;
    }
}

One way is to check whether the user has mobile data activated in the Settings, which most likely will be used if wifi goes off. This works (tested), and it doesn't use reflection, although it uses an hidden value in the API:

boolean mobileDataAllowed = Settings.Secure.getInt(getContentResolver(), "mobile_data", 1) == 1;

Depending on the API, you need to check Settings.Global instead of Settings.Secure, as pointed out by @user1444325.

Source: Android API call to determine user setting "Data Enabled"

@sNash's function works great. But in few devices I found it returns true even if data is disabled. So I found one alternate solution which is in Android API.

getDataState() method of TelephonyManager will be very useful.

I updated @snash's function with the above function used. Below function returns false when cellular data is disabled otherwise true.

private boolean checkMobileDataIsEnabled(Context context){
        boolean mobileYN = false;

        TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (tm.getSimState() == TelephonyManager.SIM_STATE_READY) {
            TelephonyManager tel = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
//          if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN_MR1)
//          {
//              mobileYN = Settings.Global.getInt(context.getContentResolver(), "mobile_data", 0) == 1;
//          }
//          else{
//              mobileYN = Settings.Secure.getInt(context.getContentResolver(), "mobile_data", 0) == 1;
//          }
            int dataState = tel.getDataState();
            Log.v(TAG,"tel.getDataState() : "+ dataState);
            if(dataState != TelephonyManager.DATA_DISCONNECTED){
                mobileYN = true;
            }

        }

        return mobileYN;
    }

You can try something like that:

ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

//mobile
State mobile = conMan.getNetworkInfo(0).getState();

//wifi
State wifi = conMan.getNetworkInfo(1).getState();


if (mobile == NetworkInfo.State.CONNECTED || mobile == NetworkInfo.State.CONNECTING) 
{
    //mobile
}
else if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State.CONNECTING) 
{
    //wifi
}

If you are interested if you are realy connected, use

NetworkInfo.State.CONNECTED

only, instead of 

NetworkInfo.State.CONNECTED || NetworkInfo.State.CONNECTING

Here is a xamarin solution to this problem:

    public static bool IsMobileDataEnabled()
    {
        bool result = false;

        try
        {
            Context context = //get your context here or pass it as a param

            if (Build.VERSION.SdkInt >= BuildVersionCodes.JellyBeanMr1)
            {
                //Settings comes from the namespace Android.Provider
                result = Settings.Global.GetInt(context.ContentResolver, "mobile_data", 1) == 1;
            }
            else
            {
                result = Settings.Secure.GetInt(context.ContentResolver, "mobile_data", 1) == 1;
            }
        }
        catch (Exception ex)
        {
            //handle exception
        }

        return result;
    }

PS: Make sure you have all the permissions for this code.

You must use the ConnectivityManager, and NetworkInfo details can be found here

I think using NetworkInfo class and isConnected should work:

ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

return info != NULL || info.isConnected();

And to check mobile data is connected perhaps. I can not be sure until I test it. Which I cannot do until tommorrow.

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

if(tm .getDataState() == tm .DATA_CONNECTED)
   return true;

To identify which SIM or slot is making data connection active in mobile, we need to register action android:name="android.net.conn.CONNECTIVITY_CHANGE"  with permission   
uses-permission android:name="android.permission.CONNECTIVITY_INTERNAL" &    uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"

    public void onReceive(Context context, Intent intent) 
 if (android.net.conn.CONNECTIVITY_CHANGE.equalsIgnoreCase(intent
                .getAction())) {

IBinder b = ServiceManager.getService(Context.CONNECTIVITY_SERVICE);
 IConnectivityManager service =  IConnectivityManager.Stub.asInterface(b);
NetworkState[] states = service.getAllNetworkState();

 for (NetworkState state : states) {

                if (state.networkInfo.getType() == ConnectivityManager.TYPE_MOBILE
                        && state.networkInfo.isConnected()) {

 TelephonyManager mTelephonyManager = (TelephonyManager) context
                        .getSystemService(Context.TELEPHONY_SERVICE);
         int slotList =  { 0, 1 };
          int[] subId = SubscriptionManager.getSubId(slotList[0]);
          if(mTelephonyManager.getDataEnabled(subId[0])) {
             // this means data connection is active for SIM1 similary you 
             //can chekc for SIM2 by slotList[1]
               .................
          }
}

}

    ConnectivityManager cm = (ConnectivityManager) activity
                        .getSystemService(Context.CONNECTIVITY_SERVICE);
                NetworkInfo info = cm.getActiveNetworkInfo();
                String networkType = "";
    if (info.getType() == ConnectivityManager.TYPE_WIFI) {
                    networkType = "WIFI";
                } 
else if (info.getType() == ConnectivityManager.TYPE_MOBILE) {

                    networkType = "mobile";
    }

According to android documentation https://developer.android.com/training/monitoring-device-state/connectivity-monitoring#java

ConnectivityManager cm =
     (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
boolean isConnected = activeNetwork != null &&
                      activeNetwork.isConnectedOrConnecting();

use TelephonyManager

TelephonyManager tm = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

tm.isDataEnabled()

According to android documentation

https://developer.android.com/reference/android/telephony/TelephonyManager.html#isDataEnabled()

Here is a simple solution from two other answers:

        TelephonyManager tm = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            return tm.isDataEnabled();

        } else {
            return tm.getSimState() == TelephonyManager.SIM_STATE_READY && tm.getDataState() != TelephonyManager.DATA_DISCONNECTED;
        }

Well there is a workaround to check if the data connection is on. But I am not sure whether it will work on every device. You need to check that. (It worked on Android one device)

long data = TrafficStats.getMobileRxBytes();
if(data > 0){
    //Data is On
}
else{
    //Data is Off
}

If you are not aware about this method, it returns the total of bytes recieved through mobile network since the device boot up. When you turn off the mobile data connection, it will return Zero (0). When you turn on, it will return the total of bytes again. But you need to aware that there is a problem which can happen when using this workaround.

  • This method will also return 0 when you reboot the phone because the calculation starts from 0 bytes.
