How to stop iPhone from using cellular data for apps I don't use?
Recently, my iPhone 4 (running the latest ios7) has started draining battery extremely fast and when I went to check what was using cellular data (usually the biggest battery drain on my phone) several pre-loaded, undeletable apps I don't even use or want to use data with were using data, even though if I remember correctly they were not before. I know to stop them from using data you press the little on/off switch in settings, but for some reason when I do that the second I exit the settings page they go right back to using data no matter how many times I switch them off. Is there any way I can stop this, because it's really killing my battery life?
You can turn off cellular data in the settings.

- Why don't I receive messages unless my cellular data is on? I got this iPhone 3 months ago. It's the 5th one. This constant problem is that sometimes I don't get messages unless my Cellular data is turned on. I need to fix this cause its really annoying. Like for example 10 ppl texted me on Christmas Day saying merry Christmas. On January 4 I turned on cellular data while in my car & then I got them all! And it's crazy because It had the date of Christmas & the exact time.
- Why does my iphone use data over night when cellular data is turned off? Every night I turn off cellular data and leave the iPhone on and one day I wake up and check my data manager and see i have already used 25 MB please help!
