If you're trying to access the Internet through Motorola Phone Tools, you will need to make sure that your phone model is supported by the software. Just access the official website, identify your device model and check the compatibility information. If it is supported, I recommend you uninstall and then reinstall Motorola Phone Tools. Also, right-click the Computer icon, select Manage and open Device Manager. Expand the Universal Serial Bus controllers list, right-click on the driver and press Uninstall. Reboot the PC, connect the phone using the USB cable and press Scan for hardware changes icon from Device Manager. If the issues persists, try updating the software to the latest version. After that, contact the telephony service provider and ask for the MMS/Internet settings.
