Vodafone Data Connect 3G card (Huawei E620 Cardbus card), which I use as a static broadband access card on a gateway machine. Sometimes I take it out and about with my lappy and even use it the way it's meant to be used.
At the time of writing the d/l speed is max 384kbps, but this is set to rise to 1.2Mbps shortly with the advent of HSDPA and could reach 14Mbps over the next couple of years (theoretically).
I'm only 4 miles from the nearest BB-enabled town, but no chance of getting landline BB here; so I took a chance on this Vody card and it works! I use an MMDS dish and squirt the signal the 4 miles to the access point.
