Wireless Internet connection

True wireless connections are presently limited to specific "hot-spots" in assorted locations.

These vary in access and capabilities.

Your best option for connectivity while traveling is to either contract with an ISP that has nationwide access.
Or, to contract with an ISP that works with your cell-phone provider and supports cellular access.
