As much as I would want to badmouth Verizon with the policies they've enforced or will soon enforce, they've been good to me for over 7 years. I've only had one major issue with them and it was a glitch in their system that didn't automatically withdraw funds for my monthly bill, that they didn't bother telling me until a month later after it was due. Part my fault because I should have checked, but they should have alerted me as well.
It is a shame that they're following suit behind AT&T's game, but things have changed ever since smartphones became popular. I'm willing to bet that when, not if, Verizon goes to a tiered program, they'll be a little more reasonable than AT&T with their prices. Pretty soon, you'll see T-Mobile and Sprint going down the same road. But that's why I am going ahead and buying a new DC tomorrow to lock in my unlimited data for the next two years. Even if they don't change to tiers until the end of the year, it's better safe than sorry.
Anyway, back on topic. Does anyone know why the DC is using so much data if no one tethers?
