My mobile contract recently expired and instead of upgrading with a new mobile phone I chose the Huawei E170 T-Mobile Web 'n' Walk Stick. They seemed a bit confused at this request at first and had to 'speak to their superiors' but eventually agreed that there was no reason that I shouldn't be sent the USB Stick. This means I can add on the Web 'n' Walk Plus or Max packages as and when I need them at the discounted rates when using them as add ons.
To get the USB Stick to work with Mac OS X Leopard though you'll will need to do a few things for yourself as the Web 'n' Walk stick manager software crashed repeatedly when I tried to use it to connect. Here are the steps:
You should now be connected using your modem. Simple really! I actually noticed once connected you can open the Web 'n' Walk stick manager software to monitor the connection. Considering it's this simple I think its a bit misleading that T-Mobile say the device isn't supported on Leopard. Feel free to share your experiences below in case there are other issues.
