Ok, so was looking at wife's phone today (iPhone 6) and noticed that in 1 week she has used 3.8gb of data....we only have 5gb to share. So here is my question(s) If you leave your LTE on at all times and then use wifi at home, does the wifi overthrow the LTE and only use wifi? She claims that she turns wifi on when she's at home and didn't have this problem with her 4s. I have changed her apps from pulling from LTE all the time and pushing notifications. Would the LTE being on in the background all the time really use that much data in one week? I keep my data/wifi off at night when I'm sleeping and usually while im at work, since I can't use my phone and then I'll turn on LTE at lunch to check all my stuff and then when I get home, I turn on wifi and make sure LTE is off and in one week, I've used 412 mb of data. Also, does keeping LTE off prevent you from getting texts? Some seem to go through fine, but I'll notice if I've had LTE off for a while, when I do eventually turn it back on, I'll have texts that pop up that should have been received hours ago and these are just normal texts with no pics/videos. Do you guys leave your LTE on at all times when no wifi is available?
