You will more than likely have free internet for like searching google and that, but when it comes to watching videos and downloading your free data will be drained rapidly and you will be charged when you use up your free data

  • Will using cellular data use up my credit? I'm getting an iPhone 5 quite soon on pay as you go and don't want to waste credit. If I turn off cellular data then will my credit be only used for calls and texts? I'm happy with using just Wi-Fi.
  • Why does my iPhone still charge for Internet even when I'm not using Internet? So, I recently got a pay monthly plan with my new iPhone 4s. When i'm out and about I'm usually updating my twitter and Facebook account. But, when I'm put my phone down, 3G still says I'm using it and charging me. So do I have to turn it off when i'm finished? Or is there a much easier way?

  • Using Wi-Fi on iphone's (vodafone)? I have got a new iphone and I'm on a contract with 500mb of internet, I'm with vodafone and I was wondering wether using the internet while connected to Wi-Fi (my home Wi-Fi not a hotspot) instead of mobile data uses up my data allowance?
