Emoticons are special characters that can only be included in a Unicode SMS. These messages have a capacity of 70 characters and can be concatenated that the recipient will receive. as a single message. More information at Types of SMS messages.
Emoticons are available on all submission forms as long as the account has Unicode SMS enabled in the Account Preferences.
The design and final appearance of each emoticon will depend on recipient's device and operating system.
We recommend the use of emoticons especially at the beginning of the message as they increase the reading rate and impact on the recipients.
