Wi-Fi is needed to use Facetime. You could also use data to make the call.
If you are using a Mac, you can download the FaceTime app of the Mac App Store (You may need to update you Mac Software If you do not have a Mac App Store). On a iPhone 4 or iPhone 4S to FaceTime select the contact you want to call in the Phone App or in the Contacts App. Instead of taping on their phone number, scroll down and you will see a button that says FaceTime. You must be connected to a Wi-Fi to use FaceTime.
Yes, the iPhone 3G has Wi Fi.
FaceTime on the iPod Touch is using the camera on the iPod to have a video chat with another person with FaceTime for the iPod Touch or iPhone. You must have a Wi-Fi connection to initiate FaceTime, and the receiver also must have a Wi-Fi connection (or 3G connection for iPhones). It is good if you want to chat face-to-face without really being face-to-face.
To get Wi-Fi on your iPhoneGo to Settings > Wi-Fi > Turn it on > and choose your connection.
Do I have Wi Fi?
Yup! It's free. You will use data when you download the app if you are not on a wi-fi connection at the time. You can use the video call feature on your iPhone 4 on when connected to wi-fi, it's awesome though! Tango and Facetime are cool as well. Have fun!
No not really,because it's not a big thing like other phones with contracts.It's not as expensive as the phones with contracts because they have wi-fi and i also think that an iphone has wi-fi.
Wi-Fi is free to use on the iPhone. If you know the password of the Wi-Fi or it is unprotected. There is no cost to use Wi-Fi through the iPhone but there maybe a charge if you use Wi-Fi at a coffee shop (or place like that).
no because on facetime you can only use it on other iphone 4s
from vivek yes
One reason your Facetime may not work in Indonesia is that your Wi-Fi connections is not fast enough.
