Getting the AT&T Quicksilver USB HSDPA working on a Mac
As a note to future self and to anyone else coming home with AT&T’s QuickSilver USB HSPDA modem I’ve just jotted down my notes about it here.
The official name for this is the Option Icon 322. The helpful AT&T staff says to go the option web site to download the drivers for the Mac.
Going to the Icon 322 Download Page you get this helpful screen:
After some experimenting I discovered that the Icon 225 Download Page looked promissing. I downloaded the Mac version of their GlobeTrotter software.
Once you start installing it you will see this screen:
Make sure to ignore the instructions and insert the modem before you go any further.
Once this is installed run the application “GlobeTrotter Connect”. Before you connect you need to go to the Preferences and click on the “3G/EDGE/GPRS” tab and enter “ISP.CINGULAR” in the APN field so it looks like mine below:
Now you should be able to connect. It took way to much fiddling to get to these steps.
Warning if you have installed the tools following their instructions without the device inserted, you need to uninstall it completely and try again.

About the APN, I’m using the Option 322 on Windows, and the ISP.CINGULAR apn didn’t work. I needed to change it from ISP.CINGULAR to WAP.CINGULAR. And it must be the same for MacOS users as well, for linux users it’s the same. You should review this, just in case, and it can probably solve some of the issues some of you may have when trying to connect.
The ISP.CINGULAR is the APN for AT&T’s data card plan, so using a smartphone data plan with it set to ISP.CINGULAR will charge tons of money. Use WAP.CINGULAR for any smartphone data plan.
Yeah but there is not an option on the AT&T software for windows to change the APN. So how should I do this if I have windows?
edit: I fixed this problem by purchasing a router that lets you configure the APN and more. I can now also share the internet connection to many computers at once on an LAN. I’m sure there has to be some software for windows that will configure the modem’s APN, but I needed a mobile LAN anyway so i just did that.
