Greetings all. I travel to the north part of NH most weekends and the signal is very unreliable up there unless I change the band preference to "cell only". Otherwise, the phone keeps switching back and forth between Verizon network and Extended network. It also drains the battery rapidly as a result. I believe the extended network is actually U.S. Cellular, but I could be wrong. Anyway, my question is this: What are the ramifications of leaving the band preference set to cell only?
