About text and multimedia messages

SMS messages are also know as “text” messages and can each be around 160 characters. If you
continue to type after the limit is reached, your message will be delivered as one, but count as more
than one message. These are called “concatenated” messages.
MMS messages are also known as “multimedia” or “picture” messages and can contain text, picture,
audio, and video files.
When you compose a message, the phone will automatically convert a text message into a
multimedia message as soon as you add a subject or an attachment, or if you address the message
using an email address rather than a phone number.

The message list

Like Gmail, text and multimedia messages are grouped with the replies you receive into
conversations or “message threads” or just “threads”. Message threads are listed in order of when
you received them (newest at the top). To open a thread for reading, select it. Read more below.
Unread messages appear with a green band on the left.

The Read view

Select a message thread in the list to open it for reading. When open, the individual messages
appear stacked on the screen, much like with instant messaging conversations (or chats). Note that
messages you send are also listed in the Read view.
Reading multimedia messages If you have selected to auto-retrieve your multimedia messages,
then both the message header and body will download. (Read more in “Text and multimedia
message settings” on page 60.) To view your message, select the “play” button.
If you are downloading only the headers, then you must first select the Download button to retrieve
the message body. If you are concerned about the size of your data downloads, you can check the
message size before you download.
Once the message has downloaded, select the “play” button to view the message.
