I have the whole Verizon data vs wifi thing down. I have a question that I cant find the answer too probably because its stupid. I have been using all three of my android devices primarily at home using a wifi connection. My Cable company just sent me an email saying that I had exceeded the allotted amount of usage for this period. So question is I almost never turn these androids off and the setting is set to keep wifi connection even if the unit sleeps because reconnecting takes a couple of minutes. Am I still using data allowence through my provider if the unit is simply connected but asleep and not using internet or email?
