Communications on the road.
We solved our biggest frustration on-the-road, expensive ($3/min)cell phone plans, by going WiFi.
Our computer has built in WiFi, we signed up for Skype (the most advanced service) VOIP (Voice Over Internet Protocal)telephone, with a cheap prepaid "Skypeout" card for calling regular land line telephones anywhere in the world. (Computer to computer calls are free).
We stop and camp only at locations that offer free WiFi access (more & more campgrounds are offering this because it's cheap for them and lots of RVers like us will ONLY go where open WiFi is available).
We still have a cell phone but use it less.
