Yes. Sierra Wireless aircard 555 (CDMA) and 750 (GPRS), and Axen / Sagem GPRS

some little adaptions to /etc/pcmcia/config.opts

For Axen / Sagem GPRS no. For Sierra Wireless a CIS file in /etc/pcmcia/cis.
can be downloaded from the sierra website. Use for 32bit Linux as is, for
64bit Linux you need a small adjustment in it. Easy though.

Depends on the provider of the service, and their network quality.

If you get EDGE, that's the fastest. Go for it. (Haven't tested it myself
though, but the sierra wireless cards are the same architecture for GPRS only
and for GPRS/ EDGE.

Next is CDMA. I can download most of the with 3 times the speed of a 56k modem
dial up line. Some latency. But downloading a 4 GB DVD in 4 days is no
problem. With a dialup line you need 12 days for the same download. I'm very
happy with it (of course ADSL would be better...)

GPRS is a solution which is good if you are on the road, but it is not as good
as a 56k modem dial up line. Sometimes terrible latency. Many timeouts. But
better than nothing.

Probably not. Check if EDGE or CDMA is available with a coverage in the area
where you need it, and affordable. If they give you limited downloads (such
as 300 MB / month) in a monthly subscription, that is probably not enough,
even for just surfing and email. Look for unlimited packages.

For cdma, of course you need to check that the data service is offered where
you need it. Sometimes there is coverage for voice, but not for data.

If you get GPRS only, the axen / sagem GPRS card is the easiest to install,
and works great.
