IPhone 5 data usage for videos?

How much data (mb) is used to watch a forty min episode on abc app? I don't have Wi-Fi obviously.

Watching videos on any phone takes up a lot of data usage. I don't have an exact number of megabytes or anything like that, but 40 minutes of video is a lot. It also depends on what quality you watch the video in. The higher the quality, the more megabytes.

  • What counts as data usage on the iPhone 4S? So basically, I just want to know what counts as data usage. & also, if you have unlimited Internet, does safari still count as data usage?
  • Unknown data usage on iPhone 4S? My family and I all have smartphones (all iPhones except one) and on our phone bill, it says that we're already at 6.7 GB, in 15 days… Looking further into it, I noticed that on each phone, data was being used every hour. Like anywhere between 1 and 19, 000 KB being used exactly every hour. Like 3 KB at 1:49, 15 KB at 2:49, 7 KB at 3:49 in the morning. KB's aren't a lot, but when you have 6 devices using KB's every hour, it really adds up.
  • Under settings on my iPhone, does the data usage include Wi-Fi usage? Because its stating a ridiculous amount and I've had my data off… And my Wi-Fi on. Does the total of data include the amount of Internet I'm using when on Wi-Fi? I'm so confused
  • IPhone: settings cell usage vs AT&T's data usage number? AT&T has a number, by calling it will send you a text message telling you how much usage you have used on your data. But also in the iPhone there's a cellular usage count in the settings app which also tells how much data you have used. Both of my cellular usage counts are different. Which is right?
