If you don’t have a data plan for HTC ChaCha or you don’t have access to a Wi-Fi network, you can still go online on HTC ChaCha by using your computer’s Internet connection.
Important: Before you can use your computer as a modem, be sure to install HTC Sync on your computer first.
Make sure your computer is connected to the Internet.
Note: Two things to check for your computer’s Internet connection. One, you may need to turn off your local network’s firewall. Two, if your computer connects to the Internet via PPP (e.g. Dial UP, xDSL, or VPN), Internet Pass-through will only support TCP protocol.

On the Choose a connection type screen, select Internet pass-through, and then tap Done.
