Do I need to pay for face time?

I have an iphone 5 and I don't have very much data so I just blocked it because I don't really use it and I don't want to have my friends taking my phone and going over the data limit. And if you have to pay for phone calls do you also have to pay for facetime? Or does it just use the Wi-Fi?

You can either use cell data or Wi-Fi which is free and better quality

As long as you use Wi-Fi you should be okay. If it gies over to your 3 or 4 g then you will be xharged data usage.

  • IPhone 4 face time activation issues? I have an iPhone 4 running on iOS 9, with no service. I was attempting to activate both facetime and imessage. Imessage and facetime both say waiting for activation under settings. However, imessage is working perfectly. When ever I try to make a facetime call it instantly says call failed. I even had my friend try to facetime me and it said unavalible for facetime. Are there any solutions too this?
