Your Treo 650 is within range (30 ft.) of the device with Bluetooth wireless

The Treo 650 Won't Connect to the Internet
Your Treo 650 supports Sprint PCS Vision, a way to connect to the Internet that is

customers can connect to the Internet, but to avoid high per-minute charges, we
recommend that you subscribe to a Sprint PCS Vision plan.
Press and hold Power/End
device back on again.
Confirm that the DUN setting is turned off in the Bluetooth application (see
"Using Dial-up Networking on Your Treo 650" on page 82).
Perform a soft reset (see "Soft Reset" on page 258).
Contact Sprint to verify that your subscription plan includes Sprint PCS Vision
services, that these services have been correctly activated, and to confirm
your username and password. Sprint should also be able to tell you if there
are any outages in your area.
