Up in the sticks of Wisconsin's Northwoods, used to get 3-5 bars with ATT. Switched to Verizon and used to get 3-4 bars, now nothing and spotty/dropping calles. YET, after turning on 3G data service, still no bars - but outSTANDING 3G data? How can this be? And how do I fix the no bars/dropped calls issues? Coverage there is supposed to be primo, according to the Verizon map. How do I actually get that coverage - like I used to?
