Text Messaging (SMS)
You can send and recieve text messages only in GSM mode. While using the Nextel
iDEN digital network, you can only recieve text messages.
In GSM mode, you can send and receive text messages up to 160 characters in size.
While using the iDEN network, you can recieve messages up to 500 characters long.
The advantages of text messaging include the following:
• Text messages are sent instantly.
• Text messages can be sent or received at any time, except during a data call, Walkie-
Talkie call, or Talkgroup call.
• Most mobile phones support text messages, so most recipients can read text
messages that you send.
Note: You cannot synchronize text messages with your desktop computer, and you
cannot use text messages to send or receive attachments or voice notes.
Media Messaging (MMS)
Media messages are composed of 1 or more pages, and each page can contain up to 1
picture, text region, and sound. Thus, when the recipient opens your media message,
the experience is similar to watching a simple slideshow. The recipient must download
the message before viewing it.
You can create media messages of up to 100 KB in size, including pictures and sound
files.
The advantages of media messages include the following:
• After the message has been downloaded, media messages essentially “play” the
picture or sound you attach to the message, so the recipient does not have to
download each attached file.
• Media messages can be sent or received any time your Smartphone is turned on and
not in a voice or data call.
Instant Messaging
You can use MSN
®
Messenger on the Smartphone to send and receive instant
messages. MSN Messenger on the Smartphone provides the same chat environment as
MSN Messenger on your desktop computer. For example, you can chat with a single
MSN Messenger contact, or with several contacts at once. You can switch between
active chats, block contacts, and configure display settings, such as your name and
current status (Away, Online, and so on).
An external QWERTY mini-keyboard for easy text entry can be purchased at sprint.com
or by calling call 1-800-NEXTEL6.
For information on setting up the Smartphone for instant messaging, see “Sending and
Receiving Instant Messages” on page 72.
