re: #137 Anymouse
It still works when I go into an area with cell service (like Cheyenne or Denver).
It doesn’t work here because there are no cell towers. Contrary to what the cell companies say, there is no universal coverage in the USA.
Heck, here we only got 911 direct dial emergency service in 2012.
Cell coverage in China is way better than in the USA. You have to be way out in the sticks in a holler to lose signal.
