    1. I couldnot get it worked for me ever since i upgraded to El Capitan. I use Huawei E303. Could you please help me, thank you.

  12. i downloaded the OS X El Capitan and now my 8ta dongle refuses to work. When i try to connect it keeps displaying The device has been disconnected or is unavailable. i used the Dongle on another computer and it works. please help.

    1. Hi
      I went onto the link and did the download, but on the final step of installation, it says "Installer cannot install the software because there is no software found to install".

  13. For El Capitan, the old method is not working any more.
    You need to download a new driver for the modem, as El Capitan does not support it by default.
    Search for the driver on the webpage of your phone company, they should provide you the driver if they supplied you with the modem.
    My telehone company provided the drivers for their modems on this page, but I think this will not work with your device, just FYI:
