Just to share that I’ve got this HSDPA / 3.5G, and it works straight away with Ubuntu 8.04 (hardy). No problem whatsoever. Feel free to buy this too.
From what I’ve heard, it seems that the entire Sierra AirCard 8xx is the same (881, 875, etc)
This is nice, now I can browse up to 7.2 Mbps from my laptop wirelessly.
I’m subscribed with IndosatM2’s service. Since I mostly use SSH, I have a feeling that most of the time I won’t go over my 700 MB monthly bandwidth quota, heh. At this speed, using SSH over the Internet feels about as fast as accessing servers in my office’s LAN. Good stuff.
