Make & receive an AT&T Video Call
All AT&T Video Call participants need a video call capable device and a postpaid wireless account that is set up for AT&T HD Voice. At this time, Video Call is available between AT&T customers within AT&T HD Voice coverage areas and with users on carriers that interoperate with AT&T. Each call uses both voice & data (HD Voice part of the call is billed as a regular voice call, while the video portion of the call incurs data usage charges). No voice or data charges apply once a Video Call hands over to Wi-Fi. Certain features (Smart Limits, Ringback Tones, OfficeDirect and OfficeReach) are incompatible with Video Call.
