How to get sim slot number

Question

I want to get sim slot number for incoming and outgoing calls in broadcast receiver. I've tried the below code but doen't work for me

Log.d("TAG " , "SLOT" + intent.getExtras().getInt("com.android.phone.extra.slot"));

Answer 1

Try this code

TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
     String mPhoneNumber = tMgr.getLine1Number();

or check with

String getSimSerialNumber = telemamanger.getSimSerialNumber();

Also add this permission on Manifest

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

There is no guaranteed solution to this problem because the phone number is not physically stored on all SIM-cards
