The SMS is strictly limited to 160 ordinary characters & it is a worldwide standard across telephony. It makes use of the gaps between normal telephone signals, and that is why it is so cheap. An MMS is data in the real sense, and that's why you need mobile data on to use them. Emoticons and other such things are not ordinary characters, and that is why they are converted into MMS. The SMS itself is hailed to be one of the greatest inventions of the 20th Century.
Why is it a problem that is sends as an MMS?
Sent from my SPH-L720 using AC Forums mobile app
Because you get charged for sending mms unlike text messages which are free

Just noticed this behavior on my Note 3. Found this "fix":
Go to Messages > Settings > SMS/MMS
On Text Message (SMS) settings, select Input mode > GSM alphabet
Enjoy! ;D
