The first two is whether the carrier proxy is used or not. The browser uses the proxy which give only web pages formatted for mobile devices. The Internet does not use the proxy and you can access Internet locations directly. Some web pages might not be rendered correctly. Multimedia uses the proxy to send and receive messages with graphic, video and audio content. The APN settings might be different for the various choices.
