2. Select Menu >Message Options.
3. Uncheck the box labeled “Request message delivery notifications.”

Non-touch screen smartphones

1. Select Messaging >Text Messages.
2. Select Menu >Options (WM 6: Menu >Tools >Options).
3. Select Account Options (or Account Settings), and then Text Messages (if necessary).
4. Uncheck the box labeled “Request delivery notifications.”
