Mobile VOIP

Bryan Lunduke explains how "How Google Is Helping Me Live a Cellphone-Free Life ."   The article offers valuable tips for using Google Voice and Google Hangouts to reduce reliance on Skype for communicating without a cell phone.

However, Lunduke's earlier article "How I Live Cellphone Free in a Cellphone World" indicates that his VOIP (Voice Over Internet Protocol) solution only works because he used a mobile hotspot device from a cellphone company to provide the data connection he needs when away from open WiFi hotspots.   Thus Lunduke may be able to use a tablet in place of a cellphone plan, but his outdoor connectivity still relies on a mobile data provider.
