If you have no available data limit on your phone you will not be able to use FaceTime until you have access to WiFi or are able to add a working data plan or a prepaid data limit to your phone. FaceTime requires an internet connection to work, either via WiFi or cellular data. No internet connection equals no FaceTime.Hi Everyone! Can I still use facetime even if I don't have enough credit on my phone and wifi isn't available? Please let me know. Thanks.
