AT&T Video Call: Not available in all areas.
Usage/Charges: Each video call uses both voice and data (unless on Wi-Fi). The voice portion counts against voice minutes, and the video portion counts as data use under your existing wireless rate plan
Requirements: All parties to a video call must be postpaid wireless customers with Video Call-capable devices and located within AT&T HD Voice coverage. Device selection is limited at this time. Unless disabled, video call capability is displayed to other AT&T Video Call-capable customers.
Wi-Fi: Once started or received on the mobile network, video calls automatically switch to Wi-Fi if your device accesses an available Wi-Fi Internet connection. An AT&T wireless network connection is still required even while on Wi-Fi. Voice or data charges don’t apply to video calls over Wi-Fi. If you move in or out of Wi-Fi coverage areas while using Video Call, your call will disconnect unless you have AT&T HD Voice coverage.
Incompatible services or features: AT&T Video Call requires an account that’s set up for HD Voice. HD Voice isn’t compatible with AT&T PREPAID℠, AT&T Smart Limits, voice dialing, Office Direct, and OfficeReach. Go to att.com/hdvoice for more info. For more details on AT&T Video Call, see our FAQs.
