I am subscribed to our local mobile wireless internet that uses a SIM card inserted to a USB device. The device is working fine on my desktop with Windows XP and on my previous Windows Vista installation. I had to do a fresh of the Windows 7 beta because my HP DV2910US laptop's HD crashed.
After re-installing the wireless internet device's default program, it's still not working for me. It can detect the USB device but it doesn't detect the SIM card inside it. I tried re-installing my old Vista drivers related to Modem, Network, and Internet, but nothing works.
