Nokia Lumia 920 - What can I do about the emoticon is not sent over SMS from my Lumia phone?

Your phone has emoticons (smiley faces and pictures) built into the Messaging keyboard. To add the emoticon, just tap on the Happy face in the lower-left of the keyboard, and then pick one of the options. If it does not show up as the graphical icon to the receiver, try the following workarounds:

  1. Select one of the full colour smileys, not the text ones.
  2. Use the standard text messages only.

Note that the Messaging app does not automatically convert a plain text smiley faces into the graphical icons.
