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?
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.
