To complete @Android Fanatic answer

If the text is too long, the message does not go away, you have to respect max length depending of encoding.

More information can be found here.

I'd prefer this method

SmsManager sms = SmsManager.getDefault();
ArrayList parts = sms.divideMessage(message);

ArrayList sendList = new ArrayList<>();
sendList.add(sentPI);

ArrayList deliverList = new ArrayList<>();
deliverList.add(deliveredPI);

sms.sendMultipartTextMessage(phoneNumber, null, parts, sendList, deliverList);
