SMS Messaging
In addition to dialing and receiving voice calls, you can use your Treo to send and receive short
text messages. These text messages, also called SMS (Short Message Service) messages, are
similar to e-mail messages that you send and receive from your computer, but are limited to 160
characters in length. The person receiving your message must also have a GSM mobile phone
and a wireless service provider that supports text messages. Some wireless service providers also
allow you to use your Treo to send text messages to an e-mail address and to receive text
messages from a computer. Talk to your wireless service provider for details about their SMS and
SMS Email features.
Enabling SMS and SMS Email
To send and reply to SMS messages, you must subscribe to your wireless service provider’s SMS
service. If you subscribe to this service, your wireless service provider supplies an SMS Message
Center number which appears in the SMS Preferences dialog.
Note: Your wireless service provider may use a different name for their text messaging service.
Contact your wireless service provider to see if their service is compatible with SMS. Not
all wireless service providers offer SMS Email services.
