FAQ

Questions AT&T Messaging owners ask.

  • 01

    What sender IDs can I use to send SMS messages?

    You must use a registered AT&T shortcode or dedicated long code as the sender ID. Unregistered or random numbers will be rejected by the carrier. You can provision new shortcodes with keywords using the create_shortcode capability, or check your existing ones through the messaging dashboard. Each shortcode can be configured with multiple keyword auto-responses.

  • 02

    Can I send MMS with images and what formats are supported?

    Yes. The send_mms capability accepts a publicly accessible media URL. Supported formats include JPEG, PNG, GIF for images, MP4 for video, and common audio formats. The media URL must be reachable by AT&T's servers -- local or private URLs will fail. Maximum file size limits apply per carrier specifications, typically up to 1MB for images and 3.5MB for video.

  • 03

    How do I handle customer opt-out requests like STOP?

    AT&T Messaging automatically processes standard opt-out keywords (STOP, CANCEL, UNSUBSCRIBE, QUIT). When a customer sends one of these, they are added to your suppression list and will no longer receive messages from that shortcode. You can monitor inbound messages with get_inbound_messages to track opt-out activity and verify your keyword configuration with get_keyword_responses.
