If you’re not sure there will be good connectivity in your area and you simply *must* remain connected, consider a Thrane Sat Modem or its equivalent. Something like the Thrane Explorer 500 (via the BGAN network) shouldn’t set you back more than $115/week. Granted, that’s too much for the typical instant messaging with your kids, perhaps. But if your office needs you to be in touch for a few emails each day, then it’s really not a terrible deal. You can connect at up to 128K via USB. It’s pretty easy once you get the hang of it.

although that’s just one of many vendors you could research.
