Code:

private final static String simSlotName[] = {
        "extra_asus_dial_use_dualsim",
        "com.android.phone.extra.slot",
        "slot",
        "simslot",
        "sim_slot",
        "subscription",
        "Subscription",
        "phone",
        "com.android.phone.DialingMode",
        "simSlot",
        "slot_id",
        "simId",
        "simnum",
        "phone_type",
        "slotId",
        "slotIdx"
};


Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "any number"));
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.putExtra("com.android.phone.force.slot", true);
    intent.putExtra("Cdma_Supp", true);
    //Add all slots here, according to device.. (different device require different key so put all together)
    for (String s : simSlotName)
        intent.putExtra(s, 0); //0 or 1 according to sim.......

    //works only for API >= 21
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
        intent.putExtra("android.telecom.extra.PHONE_ACCOUNT_HANDLE", (Parcelable) " here You have to get phone account handle list by using telecom manger for both sims:- using this method getCallCapablePhoneAccounts()");

    context.startActivity(intent);
