Swisscom Huwei E220 on OS X 10.6 Snow Leopard

On a new OS X 10.6 Snow Leopard the Huwei E220 USB modem (from Swisscom in my case) didn’t work anymore. The USB dongle mounts and the files on the mounted drive were visible but the Unlimited Connection Manager (UCM) installer contained in the mounted drive crashed always. It’s obviously not compatible with 10.6.

To fix this you need to download the latest version from It still says on that page that only 10.4 and 10.5 are supported but it works just fine with 10.6, too.

  1. hmmm, no luck here under 10.6.3 using the latest build of UCM. still shows “insert device”. how is your current experience?

  2. I am having intermittent success with ucm 3.5 on 10.6.4 however most often it repeatedly asks for my pin then says insert device
    Any suggestions?
