I decided to call tech support again today – Monday, a working day. I figured maybe the losers were working the call centers abroad on the weekend. I was right. Today, I got someone who actually helped me change some settings on my Windows Vista. They were security settings. I had to uncheck one box under user accounts (the introductory screen) and boom! It worked. Another thing that you need to do if you are running Vista or XP with security is this: Make sure you download the software FIRST onto your desktop (The zipped version), then after you plug the card in, unzip and install the software. This will prevent your system from crashing and will recognize the device. Soon, the device driver will install and then you are all set to use your A600 Broadband card.
I am an IT person at heart. I kept googling solutions this weekend. The best one told me to download the software from the cricket website instead of relying on the broadband USB Modem to install it for me on my computer. Next, I decided to take a chance and ask for tech support on a normal working day and lied to the technician. Instead of telling her I got the blue screen of death, I told her the modem was not being recognized. She took me through the right steps to install the card, and voila, it worked. Do not let them tell you that you need to contact Windows. That is a load of crap. It is their hardware, not the software. They need to help you change the security settings not Windows. In any case, good luck. For now, I am going to see how it works since I have 30 days and then we will see. Good luck!
