As much as Skype may be available for iPhone, it definitely, despite being pretty cool, isn’t Apple’s recommendation. iPhone 4 and newer have a new application called FaceTime, created by Apple, and it is seriously cool.
No SIM Card:
If you have no SIM Card, you need to sign up for an Apple ID account first.
You do not need an Apple ID account to use FaceTime.
Open up FaceTime, and tap the contact you want to FaceTime. Or, on iPhone 4, you could use Voice Control (Siri on iPhone 4S and newer) to “FaceTime Somebody”
Eg, FaceTime some guy.
If you had a contact called some guy it would FaceTime him or her.
Hope you now know how to use FaceTime. If you need any help, just comment!
