You can connect via WiFi only in a WiFi hotspot. If you have a bluetooth cell phone, then you can connect anywhere in your cell network. Try Ikehiker's WiFi guide at:

As far as the satellite connection goes, that's way out of my area of expertise. Only think I can think of is you would need like a DirectDuo link and a WiFi router connected to that. It would be bulky and expensive. So, if you are going to be using your Axim from Antartica, you might want to invest in a larger memory card if you want to access your entire music collection.
