An SMS conversation does not allow you to really show the feelings you are feeling at that moment; this is why smileys and other graphics such as flowers and hearts were created. Not all mobile phones offer the possibility to insert native "smilies" in messages; as a result, people exploit symbols and punctuation creatively. In addition to smileys, you can create images, such as hearts, by combining graphic symbols and that you can send to someone to express your love.
Steps

Step 1. Create a new message
Open the application that allows you to send it from your mobile.
