You can view a list of the ports that need to be open for Face Time to work on Apple’s website.The way to disable security software varies widely, so you’ll need to visit the software manufacturer’s website for help with the specifics.Face Time is easy to use when it’s working properly.Before we go on, let’s go over how to use it, just to make sure you’re doing things right.Let’s begin by making sure that you are signed in with your Apple ID. Then scroll down to the Face Time button and tap on that.You should see a switch with green next to Face Time. If it still does not work, try a device reset, which can fix problems with connections to software offerings such as Face Time.If the switch is not green, then toggle it to make it green and enable the software. Here’s a helpful rule of thumb: If Face Time does not work with anyone, it’s probably a problem with your i Phone.Under that, you should see Apple ID with your ID listed, and your phone and email beneath it. If it doesn’t work with just one person, it’s probably a problem on the other person’s i Phone, i Pad, or i Pod.
Even if both you and the person you’re trying to contact have a Face Time account, that may not be all of the story.
You will either see the Wi-Fi icon or words like 3G/4G or LTE.
If you have low signal strength, Face Time may not be able to connect.
The answer is “yes” to all four, with some reasonable limits.
It will work on a Mac with OS X installed or any of the following devices (or later models): i Phone 4, a fourth generation i Pod Touch, and i Pad 2.
