What uses data for my iPhone 4s?

I have three questions: When I'm connected to Wi-Fi and I go on apps and stuff does that use data? So what uses data on the iPhone 4s? What is the cost if I go over my data limit?

Everything you do eats data. Sending and receiving text, watching videos, listening to online music, browsing, uploading, EVERYTHING.

Anything that requires internet will use Data. So that would be Facebook App, Certain game apps, Safari App, Twitter App, Etc. Just anything that requires an internet connection. IF you are unsure of what requires internet access, turn on airplane mode and try to use those apps. That's what I did. It won't allow you to use those apps because you pretty much turned off the internet connection.

If you do go over your data limit, it costs a pretty penny. AKA It's pretty expensive depending on how much you go over. Just be careful and monitor when you are using the internet and you should be fine! There are apps you can download that help you track your data too!

  • When does data for a iphone from Verizon reset? And what uses up data? I just got an iPhone and I'm getting messages that say that the "usage reset date" is 10/10. Does that mean that is the day my data will be reset? Also, what uses up data? All I've been doing since I got my iPhone is texting and looking at a few things on the internet but I'm always connected to my Wi-Fi.
  • What uses up the GB of data on my iPhone 5s? In my deal it says I have 1gb of data browsing, what uses that up?! If I had no Wi-Fi and wanted to go on snapchat or Instagram would that use up data? Also is 1GB enough?
  • What uses Data on my iPhone? - 1 I've apparently used up 90% of my allowed data that was supposed to last till the 15th. I don't have a computer so I use my phone for pretty much everything. I obviously have to cut back but I don't wanna just turn off my phone and keep it off for 3 weeks. I use FaceBook, YouTube, Tumblr, Chrome, a web proxy, iFunny, and I think that's all the APPS I use. I also listen to music on my iPhone, do I have to stop using that as well?
  • What uses data on an iPhone? So I just got my iPhone, and I have a 1GB Family Share Plan with my dad. He said to be careful about going over the data limit, or Verizon would end up charging us extra… So what uses up the data on the phone? I know that if I'm connected to wi-fi it won't be affected, but if I go on Safari or YouTube using 4G, how much will it take? Can someone tell me what exactly effects the phone's data usage?
