Those of you that have WIFI for internet does being on Facebook use up your data? Does playing games on Facebook or the internet use up your data? I have Verizon jet pack and really my usage only gets used up if I am downloading something. I can play internet euchre games and not use any data. The reason I ask is because a friend has just started using Verizon wfi and her phone is also tied in with it now and she is going through data like crazy and she seldom downloads anything. Her Wifi rounter says her wifi isn't even turned on and no bars even show. In two weeks she has gone through over 12 gb and like I said she isn't downloading squat. Something is sucking up her data. I wonder if it isn't because her phone is tied into it? But even then she doesn't download anything on her phone and she has unlimited talk and text. Anybody here can tell me what is eating her data up? She had 12 gb plan and had to add 6 more gb. Something is really wrong. I have Verizon jet pack not the router like she has and I download a lot and only use around 10 gb a month.
