I have a grandfathered ATT plan. I read I can get out of the contract if I want because of changes they are making, increasing it $5 per month. I wanted to look around and see what the competition is in 2016. Looks like I'm using 10-15GB per phone per month. My only explanation is that the kids are probably using Youtube Kids when we drive around too much. Should I stick with ATT? Also, I live in the Bay Area if that makes a difference.
