How to find out which SIM is making the outgoing call (Dual SIM)

Question

I would like to check which SIM is making an outgoing call for DUAL SIM android phones. Read this article Android : Check whether the phone is dual SIM.

Works like a charm, detects the sim state and if phone is dual SIM. Next step is to get SIM info during an outgoing call request so that i know which SIM is making the call and according to that take some action.

Can someone help me with that?

Answer 1

I've tested and for Jelly Bean I was able to successfully identify the dialling SIM card. Tested also with triple SIM device and worked like a charm.

Code snippet for this inside your BroadcastReceiver:

int whichSIM = 0; // this for security fallback to SIM 1

if (intent.getExtras().containsKey("subscription")) {

    whichSIM = intent.getExtras().getInt("subscription");

}

// do whatever you need to with the information

Answer 2

You can create BroadcastReceiver, which will accept all outgoing calls. Then:

    String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
    int slot=intent.getIntExtra("com.android.phone.extra.slot",-1); 
    //0 or 1 are valid in my case

number is dialed number
slot is through which slot you make that call
You will need to register that receiver, and give proper permissions. This works for dialed USSD codes also. It is tested on Privileg GSM S7589 2 SIM cards, Android 4.2.1

Answer 3

You can use PhoneStateListener after the call you can determine the outgoing call was from sim 1 or sim2 as shown in the code below.

    private class CallStateListener extends PhoneStateListener {


   @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            //super.onCallStateChanged(state, incomingNumber);

            switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:
                 Log.i(TAG, "Idle " + state);
                //when Idle i.e no call
                if (flag.equals("outgoingcall") ) {

                    // Put in delay because call log is not updated immediately
                    // when state changed
                    // The dialler takes a little bit of time to write to it
                    // 500ms seems to be enough
                    handler.postDelayed(new Runnable() {

                        @Override
                        public void run() {
                            // get start of cursor
                            Log.i("CallLogDetailsActivity","Getting Log activity...");

                            cur = ctx.getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null,null, CallLog.Calls.DATE + " desc");

                            int number = cur.getColumnIndex(CallLog.Calls.NUMBER);
                            int type = cur.getColumnIndex(CallLog.Calls.TYPE);
                            int date = cur.getColumnIndex(CallLog.Calls.DATE);
                            int duration = cur.getColumnIndex(CallLog.Calls.DURATION);
                            //Check if call was made from sim 1 or sim 2 , if it returns 0 its from sim 1 else if 1 its from sim 2.
                            int idSimId = getSimIdColumn(cur);
                            String callid = "0";

                            if (cur.moveToFirst() == true) {
                                phNumber = cur.getString(number);
                                callType = cur.getString(type);
                                callDate = cur.getString(date);
                                callDayTime = new Date(Long.valueOf(callDate));
                                callDuration = Integer.valueOf(cur.getString(duration));
                                dir = null;
                                int dircode = Integer.parseInt(callType);

                                switch (dircode) {
                                case CallLog.Calls.OUTGOING_TYPE:
                                    dir = "OUTGOING";
                                    break;

                                case CallLog.Calls.INCOMING_TYPE:
                                    dir = "INCOMING";
                                    break;

                                case CallLog.Calls.MISSED_TYPE:
                                    dir = "MISSED";
                                    break;

                                }


                                if(idSimId >= 0){
                                    callid = cur.getString(idSimId);
                                    }


                                cur.close();

                                boolean isDualSIM = telephonyInfo.isDualSIM();


                                if (isDualSIM) {
                                    if(callid.equals("1")){
                                        simserailno = telephonyInfo.getImeiSIM2();

Code snippet for detecting if call was made from sim 1 or sim 2

    public static int getSimIdColumn(final Cursor c) {

    for (String s : new String[] { "sim_id", "simid", "sub_id" }) {
        int id = c.getColumnIndex(s);
        if (id >= 0) {
            Log.d(TAG, "sim_id column found: " + s);
            return id;
        }
    }
    Log.d(TAG, "no sim_id column found");
    return -1;
