SMS sending to multiple numbers not being sent

Question

I am sending an SMS to multiple numbers. When I choose only one, it works, and the message is being sent immediately. But when I use multiple (3 for example) SMS Intent is opened, but after I click Send button I see "Sending..." message all the time, SMS is not sent.

Intent sms = new Intent(Intent.ACTION_VIEW);
sms.setType("vnd.android-dir/mms-sms");
sms.putExtra("address", getSMSNumbers);
sms.putExtra("sms_body", "Help!!!");
startActivity(sms);

And getSMSNumbers String looks like this: 512991220;505202222;606123456. What is wrong? Why isn't the message being sent and it's "sending" all the time?

Also I see when I have more than 1 number, it's being converted to MMS - why?

Answer 1

I managed to do this - needed to turn off "Group Messaging" in AVD Settings. App was trying to send MMS and that's why it wasn't being sent.

Answer 2

Maybe you could loop through the numbers and send messages one by one, like this

android.telephony.SmsManager.getDefault().
sendTextMessage("00112233", null, "Message body text", null, null);
