I receive a prompt to switch networks when I stream a song or video

If you receive a prompt to switch networks, you can't stream songs or videos with the Internet connection that you are using. If you switch networks, extra fees might apply. For more information, contact your wireless service provider or administrator.

To stop receiving this prompt, in the browser, press the Menu key > Options. In the General section, below Prompt Before, clear the Switching to Carrier Network for Streaming Media checkbox.
