Depends on where you are.
Wireless requires a hotspot. If you can't even get dialup where you're going, odds are there won't be wireless service.
Satellite can be expensive and a hassle. It's sensitive to the weather, the equipment needs to be properly aligned, etc etc. The one real advantage it has is that it'll work from just about anywhere on Earth.
I'd suggest looking for ISPs that serve your area.
This Cnet article will give you a bit more info on the various service types around.
One other possibility to consider is getting an "air card" from your cell phone company, or possibly a data cable from
Susteen . You can use it to get online via the cell phone network. Mine gets me (somewhat variable) access up to 100kbps (not great, but twice as good as dialup). It just costs airtime, which, with most companies, is free on nights and weekends.
