Free Evo Hotspot???
I had the pleasure of having the FBI once try and find out where I lived for an interveiw (security job thing). Now there was only two houses on that part of the highway. After driving by for two days they called in the interveiw because they could not find the house. So much for that sort of stuff.
The internet is the wild west and I love it. If they could regulate us we would still be using slide rules. I know you may have to do a web search to find out what a slide rule is.
Find and use the apps you find. If they create free service that you can use great.
