These days I look at smart phones as modern day Swiss army knives, and they are equally valuable in either setting, urban or rural. However, they are only as good as the service behind them. As a minimalist, I rarely get excited over material "things", products, etc. Communication from an EDC and survival aspect causes me to look differently at cell phones....enter Google Project Fi Why does a guy who spends half his life at sea care about his cell service? Because when I need it...I NEED it, especially overseas and in foreign countries. So, the phones run stock android and are World phones. GSM and the other, doesn't matter. The calls for through wifi first if available, then push to nearest tower (almost any provider). Problems are solved with an actual human being returned call within minutes. And the price for service is unmatched, as they refund what is not used! Can't emphasize efficient comms enough, especially during Emergency. This product has made a huge impact on my travels and family emergency comm plan. Wanted to pass on the info in hopes it may benefit someone else.
