SMS DELIVERY STATUS

Understanding SMS delivery statuses is essential for tracking the progress of your SMS messages and identifying whether they were successfully delivered to the recipient. This guide explains each SMS delivery status reported in your SMS South Africa account, including DELIVRD, UNDELIV, EXPIRED, SUBMITD, STAGED, BLIST, CANCELLED and NOROUTE, helping you interpret SMS delivery reports and troubleshoot delivery issues more effectively.

Table: SMS Delivery Statuses Provided by SMS South Africa
STATUSDESCRIPTION
DELIVRDRefers to the successful submission of the SMS to the handset. The cellular network reports the status.
UNDELIVRefers to the unsuccessful submission of the SMS to the handset, caused by inactive or unreachable numbers. The cellular network reports the status.
EXPIRED

Refers to no status update being received within the validity period. This is usually caused by the handset being off, the call going to voicemail or being redirected, or the handset being out of network reach. 

For retries, the space between retry attempts increments at different intervals.

Example: The first attempt will be once after 1 minute, then the second attempt will retry twice for every 5 minutes, after that the third attempt will retry six times for every consecutive 30 minutes and lastly will retry after the following 12 hours.

If the subscriber becomes available within the retry process, the message will be delivered.

If the subscriber remains unavailable, the retry process will continue until it completes the cycle, and will result in the message(s) expiring.

BLISTBLACKLIST: SMS delivery to the number is restricted due to a request by the owner or WASPA.
SUBMITDThe SMS has been submitted to the cellular network for delivery. We are waiting for a status update from the cellular network.
STAGEDThe SMS is waiting in the system to be submitted to the cellular network. In most cases this is for SMSes that are scheduled for a future send date.
CANCELLEDThe SMS was scheduled to be sent at a future date and time, but was cancelled by the user before the send date and time were reached.
NOROUTERefers to no route being available for the number.
