It would be great if there is an setting options to send sms using Sim1 or Sim2.. this is useful for dual SIM android phones. I created sms application android I've been able to sms application smoothly but default sms sent by SIM 1.But I want to send the sms programmatically by setting to send the sms by sim1 or sim2?

Answer 1

You can use this code for API level 22+ (Android 5.0) LOLLIPOP_MR1.

private void sendDirectSMS() {

    private static String SENT = "SMS_SENT", DELIVERED = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(
        SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
        new Intent(DELIVERED), 0);

    // SEND BroadcastReceiver
    BroadcastReceiver sendSMS = new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    showSnackBar(getString(R.string.sms_sent));
                    Analytics.track(AnalyticsEvents.SEND_REMINDER_SMS_APP_SUCCESS);
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    showSnackBar(getString(R.string.sms_send_failed_try_again));
                    Analytics.track(AnalyticsEvents.SEND_REMINDER_SMS_APP_FAILED);
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    showSnackBar(getString(R.string.no_service_sms_failed));
                    Analytics.track(AnalyticsEvents.SEND_REMINDER_SMS_APP_FAILED);
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    showSnackBar(getString(R.string.no_service_sms_failed));
                    Analytics.track(AnalyticsEvents.SEND_REMINDER_SMS_APP_FAILED);
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    showSnackBar(getString(R.string.no_service_sms_failed));
                    Analytics.track(AnalyticsEvents.SEND_REMINDER_SMS_APP_FAILED);
                    break;
            }
        }
    };

    // DELIVERY BroadcastReceiver
    BroadcastReceiver deliverSMS = new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), R.string.sms_delivered,
                        Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getBaseContext(), R.string.sms_not_delivered,
                        Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    };

    registerReceiver(sendSMS, new IntentFilter(SENT));
    registerReceiver(deliverSMS, new IntentFilter(DELIVERED));
    String smsText = getSmsText();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
        SubscriptionManager localSubscriptionManager = SubscriptionManager.from(context);
        if (localSubscriptionManager.getActiveSubscriptionInfoCount() > 1) {
            List localList = localSubscriptionManager.getActiveSubscriptionInfoList();

            SubscriptionInfo simInfo1 = (SubscriptionInfo) localList.get(0);
            SubscriptionInfo simInfo2 = (SubscriptionInfo) localList.get(1);

            //SendSMS From SIM One
            SmsManager.getSmsManagerForSubscriptionId(simInfo1.getSubscriptionId()).sendTextMessage(customer.getMobile(), null, smsText, sentPI, deliveredPI);

            //SendSMS From SIM Two
            SmsManager.getSmsManagerForSubscriptionId(simInfo2.getSubscriptionId()).sendTextMessage(customer.getMobile(), null, smsText, sentPI, deliveredPI);
        }
    } else {
        SmsManager.getDefault().sendTextMessage(customer.getMobile(), null, smsText, sentPI, deliveredPI);
        Toast.makeText(getBaseContext(), R.string.sms_sending, Toast.LENGTH_SHORT).show();
    }
}

Don't forget to add permission in your AndoridManifest.xml.

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

Answer 2

Here's a full sample, showing how to choose one, and tested on real device (OnePlus 2) with 2 sim cards. Note that you should handle permissions (grant them before using the code) :

manifest

    <uses-permission android:name="android.permission.SEND_SMS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!--    <uses-permission android:name="android.permission.READ_SMS" />-->
<!--    <uses-permission android:name="android.permission.READ_PHONE_NUMBERS" />-->

build.gradle

        targetSdkVersion 29

Answer 3

SOLUTION WITHOUT android.permission.READ_PHONE_STATE

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
        SubscriptionManager subs = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
        if (subs != null) {
            Log.d("sim_spalsh", "num sims = " + subs.getActiveSubscriptionInfoCountMax());

            if (subs.getActiveSubscriptionInfoCountMax() > 1) {

                //SendSMS From SIM One
                SmsManager.getSmsManagerForSubscriptionId(0)
                        .sendTextMessage(phonenumber, null, "sim1", null, null);

                //SendSMS From SIM Two
                SmsManager.getSmsManagerForSubscriptionId(1)
                        .sendTextMessage(phonenumber, null, "sim2", null, null);

            }
        }
    }

Your have to guarantee the <uses-permission android:name="android.permission.SEND_SMS"/>

Answer 4

SmsManager.getSmsManagerForSubscriptionId(int subscriptionId).sendTextMessage(String destinationAddress, String scAddress, String text,PendingIntent sentIntent, PendingIntent deliveryIntent);

this can be working after 5.1 Lollipop version.before that we need to see more. once i got the answer i will update.

Answer 5

The option is available in Android Settings- navigate to Settings>>Wireless & Networks>>SIM Management>>Default Settings>>Messages>> and select 'Always Ask".

You should check out tasker, you would be able to user it to build a toggle widget for that.
