Step 1

Create a project like this:

Step 2

Create an XML file with the following:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="15dp"
android:text="Phone Details"
android:layout_centerHorizontal="true"
/>
</RelativeLayout>

Step 3

Create a Java file with the following.

In this, you will create a TelePhonyManager object and call the methods regarding the details you want to show on the activity.

package com.androidtelephonymanagerexample;
import android.content.Context;
import android.os.Bundle;
import android.app.Activity;
import android.telephony.TelephonyManager;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
TextView textView;
String setType;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.textView);
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String deviceId = telephonyManager.getDeviceId();
String simSerialNumber = telephonyManager.getSimSerialNumber();
String networkCountryIso = telephonyManager.getNetworkCountryIso();
String simCountryIso = telephonyManager.getSimCountryIso();
String deviceSoftwareVersion = telephonyManager.getDeviceSoftwareVersion();
String voiceMailNumber = telephonyManager.getVoiceMailNumber();
String simOperatorName = telephonyManager.getSimOperatorName();
int networkType = telephonyManager.getNetworkType();
if(telephonyManager.getPhoneType()==1)
{
setType="GSM";
}
textView.setText("deviceid:" + deviceId + "" + "\n simSerialNumber:" + simSerialNumber + "" + " \n networkCountryIso :" + networkCountryIso + "" + "\n simCountryIso :" + simCountryIso +
"" + "\n deviceSoftwareVersion :" + deviceSoftwareVersion + "" + "\n voiceMailNumber :" + voiceMailNumber + "" + "\nNetworkType: " + networkType + "" + "\nsimOperatorName: " +
simOperatorName+""+"\nphoneType:"+setType+""+"\nnetworkType:"+networkType);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

Step 4

Provide the following permission in the Android Manifest.xml file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.androidtelephonymanagerexample"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="16" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.androidtelephonymanagerexample.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
