Device and network requirements
Picture and video messaging uses Multimedia Messaging Service (MMS) to send and receive audio, video, and picture messages. To use picture and video messaging:
- You must have a picture and video messaging-capable wireless phone.
- You must be on an LTE or GSM network supporting GPRS transport.
- Your phone must be on and in a data coverage area to receive the picture or video message.
- If the phone is off or out of the coverage area, the message will be stored for up to 72 hours and delivered when the phone becomes available.
Picture and video message size limits
The AT&T mobile broadband network delivers picture, video, or audio messages of up to 1MB:
- Larger media file attachments are compressed before sending to keep the message size below 1MB.
- The maximum size for sending and receiving picture, video, or audio messages is also dependent upon the recipient's device and the limitations of other carriers' networks (e.g., other carriers may have a lower message size limit than AT&T).
