Call from second sim

I have a dual sim android phone. I am using this code to make a call:

private void callBack(String phone, Context context) {
        Intent callIntent = new Intent(Intent.ACTION_CALL)
                .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        callIntent.setData(Uri.parse("tel:" + phone));
        context.startActivity(callIntent);

    }

It's working fine. But it always makes call from sim1(preferable sim). How do I make calls from Sim2? Is there a way to handle dual sim phones?

Solution

  • This seems to work on a large range of dual sim devices as Motorola, Micromax, HTC, Samsung

    intent.putExtra("com.android.phone.extra.slot", 0); //For sim 1

    OR 

    intent.putExtra("com.android.phone.extra.slot", 1); //For sim 2

    and if doesn't work try this, In Samsung S duos this works just fine.

    intent.putExtra("simSlot", 0); //For sim 1

    OR

    intent.putExtra("simSlot", 1); //For sim 2

    unfortunately for these things we have to get into hit/trial mode as no official documentation is there for dual-sim support.
