How I get the facetime app on an iPhone?

Need help

Shouldn't it come with it? Check the App Store if not.

It should be on it… Check app store or if your phone needs updating. If your phone needs updating and you update it it might show up

You need later hardware for that, if your phone is several years old then you probably can't use facetime anyways.

There's no FaceTime app for the iPhone. You simply call someone and if they have and iPhone that has a front facing camera in the little options menu (where there are options to mute your mic, speaker phone etc.) you tap on the button that is labeled "FaceTime" and it will automatically work.

Its isn't an app on the iPhone, you simply add somebody with an iPhone.call them and a FaceTime option will be available!

It is not an app. You need to turn on FaceTime by going to Settings - FaceTime and then turn it on.

To FaceTime someone, call them (if they have an iPhone) and tap on the FaceTime icon on the phone call screen.
Another way to do so is to go to the Contacts app, tap on the contact you want to call, and then tap on the button "Facetime" in their contact window.
