Using Telephony Manager In Android with Example

The Android Development Tutorials blog contains Basic as well as Advanced android tutorials.Go to Android Development Tutorials to get list of all Android Tutorials.

 Telephony Manager

Telephony Manager provides access to information about the telephony services on the device. Applications can use the methods in this class to determine telephony services and states, as well as to access some types of subscriber information. Applications can also register a listener to receive notification of telephony state changes.

You do not instantiate this class directly; instead, you retrieve a reference to an instance through Context.getSystemService(Context.TELEPHONY_SERVICE).

Permission Required: 


To work with Telephony Manager and to read the phone details we need
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>           permission.So  add this permission in  your manifest file.

Accessing the Telephony Manager:

Have an  object of TelephonyMnager
TelephonyManager  tm=(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

Get IMEI Number of Phone

         String IMEINumber=tm.getDeviceId();

 Get Subscriber ID

          String subscriberID=tm.getDeviceId();

  Get SIM Serial Number

            String SIMSerialNumber=tm.getSimSerialNumber();

 Get Network Country ISO Code

             String networkCountryISO=tm.getNetworkCountryIso();

 Get SIM Country ISO Code

               String SIMCountryISO=tm.getSimCountryIso();

 Get the device software version

               String softwareVersion=tm.getDeviceSoftwareVersion()

 Get the Voice mail number

               String voiceMailNumber=tm.getVoiceMailNumber();


 Get the Phone Type CDMA/GSM/NONE

/ /Get the type of network you are connected with 
            int phoneType=tm.getPhoneType();

            switch (phoneType)
            {
                    case (TelephonyManager.PHONE_TYPE_CDMA):

                               // your code
                                   break;
                    case (TelephonyManager.PHONE_TYPE_GSM) 

                               // your code                 
                                   break;
                    case (TelephonyManager.PHONE_TYPE_NONE):

                               // your code              
                                    break;
             }


 Find whether the Phone is in Roaming, returns true if in roaming

             boolean isRoaming=tm.isNetworkRoaming();
              if(isRoaming)
                      phoneDetails+="\nIs In Roaming : "+"YES";
              else
                     phoneDetails+="\nIs In Roaming : "+"NO";


Get the SIM state/Details

            int SIMState=tm.getSimState();
            switch(SIMState)
            {
                    case TelephonyManager.SIM_STATE_ABSENT :
                        // your code
                        break;
                    case TelephonyManager.SIM_STATE_NETWORK_LOCKED :
                        // your code
                        break;
                    case TelephonyManager.SIM_STATE_PIN_REQUIRED :
                        // your code
                        break;
                    case TelephonyManager.SIM_STATE_PUK_REQUIRED :
                        // your code
                        break;
                    case TelephonyManager.SIM_STATE_READY :
                        // your code
                        break;
                    case TelephonyManager.SIM_STATE_UNKNOWN :
                        // your code
                        break;
           
            }





How to Get IMEI number of the Phone


Getting  Network Details


// Get connected network country ISO code
String networkCountry = telephonyManager.getNetworkCountryIso();


// 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) :"  Your Code ":
break;
case (TelephonyManager.NETWORK_TYPE_CDMA) :"  Your Code ":
break;
case (TelephonyManager.NETWORK_TYPE_EDGE) : "  Your Code ":
break;
case (TelephonyManager.NETWORK_TYPE_EVDO_0) :"  Your Code ":
break;





 

Getting SIM Details :


Using the Object of Telephony Manager class we can get the details like SIM Serial number, Country Code, Network Provider code and other Details.

int simState = telephonyManager.getSimState();
switch (simState) 

{
            case (TelephonyManager.SIM_STATE_ABSENT): break;
            case (TelephonyManager.SIM_STATE_NETWORK_LOCKED): break;
            case (TelephonyManager.SIM_STATE_PIN_REQUIRED): break;
           case (TelephonyManager.SIM_STATE_PUK_REQUIRED): break;
           case (TelephonyManager.SIM_STATE_UNKNOWN): break;
           case (TelephonyManager.SIM_STATE_READY): 

            {
                         // Get the SIM country ISO code
                       String simCountry = telephonyManager.getSimCountryIso();
                         // Get the operator code of the active SIM (MCC + MNC)
                      String simOperatorCode = telephonyManager.getSimOperator();
                       // Get the name of the SIM operator
                      String simOperatorName = telephonyManager.getSimOperatorName();
                        // -- Requires READ_PHONE_STATE uses-permission --
                        // Get the SIM’s serial number

                       String simSerial = telephonyManager.getSimSerialNumber();

          }
}

    1. For that you need to Implement BootReciver which will execute when Device completes boot process.
      On bootcompleted, check if the previous SIM card number is same as the Current SIM card number.
      You can go through the topic http://learnandroideasily.blogspot.in/2013/07/bootcompleted-broadcastreceiver-in.html

      If you need more help, pls let me know.
