Amazon.com Product Description
The AirCard 875U USB modem is the latest addition to the Sierra Wireless family of wireless products. Packaged in a stylish, compact housing, the AirCard 875U USB modem either plugs directly into your laptop's USB port, letting users enjoy global wireless connectivity whether waiting at an airport, relaxing at a hotel, or meeting a client at a restaurant. The result is one of the best mobile and fixed wireless solutions on the market, and a great alternative to both PCMCIA and ExpressCard solutions. With tri-band HSDPA functionality, the AirCard 875U provides wireless data connectivity on the 850, 1900, and 2100 MHz bands at speeds of up to 3.6 Mbps downlink and 384 Kbps uplink. In areas where HSDPA is not available, the AirCard 875U is backwards-compatible with UMTS, EDGE and GSM/GPRS networks (850, 900, 1800, and 1900 MHz). If an HSDPA network is not readily available in your area, the AirCard 875U will connect to the fastest available network to keep you online. Fast HSDPA network speeds provide a rich experience for a wide variety of applications, including increased e-mail speed when downloading large files; Internet/intranet access; video conferencing and surveillance; real-time media streaming; online gaming; and corporate server (using VPN) access.

 Poor Service February 28, 2008
This card sucks! I don't get reception anywhere except at the At&T store. I cannot cancel it. I am stuck with this worthless thing.
Chronic Service Don't Buy February 9, 2008
This is pathetic - the only place I can get a connection is by going to the at@t store....
I lost out on the 30 day thing but will be getting a class action lawsuit against at@t for a terrible service....
This really is disgusting - I feel mugged.

Good at First then gets worse and worse February 5, 2008
I have gone through 2 now. at first it works fine and it's not very big, but then it will get real hot and then stop working either that or it will take forever to open a page.
 Much better than dial-up January 23, 2008

I live in a rural area where high speed phone or cable internet access is not available so I decided to go with the ATT USB Modem card. It works great for me, compared to my old dial-up line. My son gets a good laugh when I mention it is fast, he has a fiber-optic internet connection. It does seem to spend a lot of time "paused", like I am sharing the connection with many other people. Also, it needs a manual way to choose the "Edge" or the "3G" network. When I am at work in McKinney TX, just north of Dallas, it has only one bar in "3G" mode and is constantly dropping out. When it does use the "Edge" network in McKinney it gets 4 bars and works much better, but then it automatically switches back to the weak 3G network when it receives that signal.
Tried an ATT USB 881 modem AND an Option GT Max 3.6 card December 28, 2007

As an existing ATT cellphone customer, I tried an ATT USB 881 modem AND an Option GT Max 3.6 card for my NJT train trips from Morristown NJ to Grand Central and for use in the building I work in near Grand Central. Of the two, the GT Max was slightly faster. But the ATT network was like an intermittent dial-up connection; real slow, and lots of drops.
Without closing the ATT account, I went and got a Verizon account with a 5750 card. It's almost like a cable connection; 10x as fast as the ATT network, and a good connection ALL THE WAY from Morristown to Grand Central, although signal strength varies. I'm writing this in the tunnel as we approach Grand Central, and I still have 4 bars. The ATT network was long dead by this point in the trip.
The Verizon connection also works fine in my suburban Morris County residence - the ATT network didn't work at all there. I'm going to return all the ATT equipment and close that account before my 30 day trial runs out!
