I'm trying to send a text messages to a friend of mine that uses Treo 650 (Sprint).

All she sees is my name but the message is blank.

Sending a message from BB Curve to the same user works.

What's causing the problem? I'm not even sure where to start researching.

Treo may not have SMS provisioned properly.

How long is your message? I think text are limited to 120 chars even though your BB will let you keep typing...
