Summary
FaceTime gives you a chance to make visual phone calls, which can be handy for talking and seeing a loved one or helping you show someone an item or scene around you. By connecting to a Wi-Fi network, you can make free phone calls without affecting any monthly data allotment that might restrict how many phone calls you can make.
For entertainment, consider using FaceTime's various visual effects, such as displaying text or animated cartoon images. Such visual effects can make a video call through FaceTime even more entertaining and enjoyable.
FaceTime gives you yet another way to communicate with others with your iPhone, just as long as you only want to talk to people who also have an iPhone, iPad, or Macintosh.
While FaceTime can be a way to entertain yourself with others, you can also turn your iPhone into an ebook reader so that you can entertain yourself wherever you take your iPhone.
