■ Text Messages
When composing text messages (SMS) or enhanced messages (EMS,
messages that can contain graphics, sounds, animations, or formatted
text), the number of characters used (out of a maximum per message)
appears in the top left corner of the message screen. Segments are created
when the message length exceeds the maximum allowed number of
characters. The number of segments used (out of a maximum of 7)
appears in the top right corner of the message screen. No additional
text can be entered when all segments and characters have been used.
Segments are delivered as individual messages. Enhanced messages
cannot be sent to e-mail addresses. For information on entering text
into messages, see "Text Entry," p. 25.
