Cingular Communications/AT&T is announcing a pair of new HSDPA-capable laptop data cards that work globally, and will work with any laptop computer having either an ExpressCard slot or a USB port. The ExpressCard version started shipping on April 25, while the USB card starts shipping in about a week.

Both cards are part of AT&T’s LaptopConnect portfolio. The Option GT Max 3.6 Express card is designed for ExpressCard slots, found in newer laptop computers. The Sierra Wireless AirCard 875U works with USB-equipped computers, which is basically all of them. Both of the data cards use AT&T’s 3G BroadbandConnect service. According to the company, they are “slim and stylish.”
