Okay so let me start by stating my current set up: iPhone 5s, AT&T, unlimited Text, Calls, 15gb month plan SHARED. Former setup: HTC Evo 4g, Virgin Mobile, Unlimited Data, Text, Calls.
My problem is this… My girlfriend, has the same phone as I do except she has one thing that I don't, WiFi. She has it at home and at work so in reality, the 15gb data plan is pretty much all mine. The first month of AT&T service after switching from Virgin, we were on the 10gb data plan which we blew thru in about 8 days. Has to be some type of mistake right? Wrong. We were forced to switch to the 15gb plan. The usage was a few YouTube videos, Instagram, Spotify a few hours a day at the gym, a few game aps, eBay, Craigslist, the usual. Since then I have turned off everything including LTE (except for messages) deleted all apps and ONLY turn data back on things when I need them, use them for a sec then turn their data back off. We are now a week into the billing cycle and it looks like we are going to be close to going over. When I was on virgin mobile with unlimited data I was riding on 4g 24/7. I would have spotify on from the moment I woke up to the moment I got off work, I would watch continuous YouTube videos as well as play game aps. I would even watch netflix about 4 hours a night. I finished the entire series of DEXTER in ONE billing cycle. My data usage NEVER went passed 6gb of data and must I remind you I was never on wifi. Is AT&T Charging 3mb for every 1mb I ACTUALLY use?
