There are several companies offering subscriptions and/or pay-per-use plans for WiFi using their own network of hotspots like AT&T (Freedomlink), an outfit called Hotspotzz and several others. There are also free hotspot locations at local libraries, some campgrounds, some hotels, etc.

If we travel this year I would like to know what I should know about WiFi access while on the road. What company plans (if any) are worthwhile, what risks (if any) there are to personal data, what difficulties are encountered, what else I should consider.

Any mudcatters have any experience or advice to offer?
