but how does it work in the woods fields and desert? Lets say your camping or going cross country?
Woods, fields, camping, cross country? In my country I have always been able to still get a mobile signal even in these places. As for a desert, I wouldn't be able to tell you...I guess you'd need a satellite phone and use it for dial-up or something.
what about the guy that mysteriously gets blocked from every wifi he connects to where changing mac and IP doesn't work?
You're doing it wrong.
