At CTIA 2010, T-Mobile boasted that it would soon have the fastest 3G network in the U.S. and introduced several new products to take advantage of its HSPA+ network, including the T-Mobile WebConnect Rocket USB Laptop Stick. Theoretically, HSPA+ can deliver download speeds that are up to three times faster (up to 21Mbps) than current 3G technology, and while we didn't quite achieve that nirvana on the WebConnect Rocket, we were impressed by its performance, as it provided some of the fastest download and upload speeds from a cellular modem we've seen, even the 4G Sprint Overdrive.
The caveat, however, is that T-Mobile's HSPA+ network is pretty limited at this point, covering just Philadelphia, New York, New Jersey, Long Island, Washington, D.C., and soon Los Angeles. Also, it requires a two-year data plan of $59.99 per month with a 5GB data cap, which is the norm, but we can see users easily going over that limit given the speeds we got, and that won't come cheap. T-Mobile's overage fees are $0.20 per MB, so be sure to keep track of your usage. The T-Mobile WebConnect USB Stick costs $49.99 and can also be bought without an annual contract with an Even More Plus Plan.
Manufactured by Huawei, the T-Mobile WebConnect Rocket measures 3.4 inches long by 1.1 inches wide by 0.5 inch thick and weighs 1.1 ounces. It's slightly larger than a typical flash drive but still travel-friendly. In addition, the USB port connector is retractable, via the slider control on the face of the device, so you don't have to keep track of any protective caps, which inevitably get lost.
