Hi, I think you should get a GSM/GPRS card. You would then get GSM (CSD) connectivity (i.e. 9600 bps data calls billed by the minute), but also GPRS access (i.e. "always-on", packet-switched, up to 50 Kbps, billed by volume). I believe all such cards look like serial cards, but I wouldn't guarantee it. The alternative is to use a GSM/GPRS phone, and connect it via a serial cable, IRDA, or Bluetooth. You need a subscription with a GSM provider that will give you a SIM card to put either in the GSM/GPRS PC card or the phone, with the GPRS option active. Roaming with GPRS is a lot less developed than with GSM, but it's growing. You might want to have a look at http://www.psg.com/~randy/gprs-ppp.html which talks a bit about this. Otherwise the good old modem also works great :-) Neither CSD nor GPRS will give you decent latency :-( Hope that helps, Jacques.
