Get device details in android (TelephonyManager)

1.Create a class SystemStatus_Utils

import android.content.Context;
import android.telephony.TelephonyManager;

public class SystemStatus_Utils {

    public static String fetch_tel_status(Context cx) {
        String result = null;
        TelephonyManager tm = (TelephonyManager) cx
            .getSystemService(Context.TELEPHONY_SERVICE);//
        String str = "";
        str += "DeviceId(IMEI) = " + tm.getDeviceId() + "\n";
        str += "DeviceSoftwareVersion = " + tm.getDeviceSoftwareVersion()
            + "\n"; 
        str += "Line1Number = " + tm.getLine1Number() + "\n";
        str += "NetworkCountryIso = " + tm.getNetworkCountryIso() + "\n";
        str += "NetworkOperator = " + tm.getNetworkOperator() + "\n";
        str += "NetworkOperatorName = " + tm.getNetworkOperatorName() + "\n";
        str += "NetworkType = " + tm.getNetworkType() + "\n";
        str += "PhoneType = " + tm.getPhoneType() + "\n";
        str += "SimCountryIso = " + tm.getSimCountryIso() + "\n";
        str += "SimOperator = " + tm.getSimOperator() + "\n";
        str += "SimOperatorName = " + tm.getSimOperatorName() + "\n";
        str += "SimSerialNumber = " + tm.getSimSerialNumber() + "\n";
        str += "SimState = " + tm.getSimState() + "\n";
        str += "SubscriberId(IMSI) = " + tm.getSubscriberId() + "\n";
        str += "VoiceMailNumber = " + tm.getVoiceMailNumber() + "\n";

        int mcc = cx.getResources().getConfiguration().mcc;
        int mnc = cx.getResources().getConfiguration().mnc;
        str += "IMSI MCC (Mobile Country Code):" + String.valueOf(mcc) + "\n";
        str += "IMSI MNC (Mobile Network Code):" + String.valueOf(mnc) + "\n";
        result = str;
        return result;
      }
}

2.Use in your MainActivity

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
    String strinfo =    SystemStatus_Utils.fetch_tel_status(MainActivity.this);
        System.out.println("INFO : "+strinfo);
    }

}


3.Add permission in manifest file

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