You use SMS status values to track outbound messages from creation through final delivery. You review the common outbound sequence below. You also review the final statuses returned after delivery processing ends.

Status for outbound messages

When you send outbound messages, you may see the following status sequence:

Status	Description
QUEUE	You see this status after your request reaches Messangi. You know the message is waiting for processing.
DEQUEUED	You see this status when the message leaves the queue. You know the message is moving to the mobile operator.
CODE_NOT_ALLOWED	You see this status when the sender is not activated or cannot message the recipient. You contact support to verify the sender.
INCOMPLETE	You see this status for segmented messages with pending segment statuses. You get segmented messages after exceeding 160 GSM-7 characters or 70 Unicode characters.
BLACKLISTED	You see this status when the recipient phone number is on a blocklist. You know the message was not sent to that number.
SEGMENTS_EXCEEDED	You see this status when the message exceeds the permitted segment limit. You keep SMS messages under 1600 characters to avoid this status.
EXHAUSTED	You see this status when the retry limit is reached. You know delivery attempts have stopped.
SENT	You see this status after Messangi dispatches the message to the mobile operator. This status does not confirm delivery to the recipient device.
