If you have subscribed to a message network service, you can send and receive 
messages to compatible phones also subscribed to a message service. You can 
also send and receive multimedia and e-mail messages if supported by your 
network operator. Also, you can make distribution lists that contain phone 
numbers and names from your contacts list. See "Text entry," p. 21.
When composing text or multimedia messages, check the number of characters 
allowed in the top right corner of the message. Using Unicode characters takes 
up more space. With Unicode characters in your message, the indicator may not 
show the message length correctly. Before sending the message, the phone tells 
you if the message exceeds the maximum length allowed for one message. 
Important: Exercise caution opening messages. Messages may contain 
malicious software or otherwise be harmful to your device or PC.
Note: When you send a message, your device may display
Message sent
,
indicating your device has sent the message to the message center 
number programmed into your device. This is not an indication that the 
message has been received at the intended destination. For more details 
about messaging services, check with your network operator.
