The SMS Delivery Details Report shows the delivery status of each individual SMS sent. Access it from SMS → SMS History → Details. There are five possible statuses:
📤 SENT
Your message has been submitted to the carrier's SMSC (Short Message Service Centre) and is awaiting delivery confirmation.
The message may already be delivered, but the carrier SMSC failed to return a delivery status.
✅ DELIVERED
Your message has been delivered to the destination mobile number and acknowledged by the carrier SMSC.
📋 Malaysia DLR note: DELIVERED status confirms receipt at the Telco SMSC — not necessarily delivery to the recipient's physical handset. Handset-level DLR is not provided by Malaysian operators by default.
❌ UNDELIVERED
The message validity period expired — the destination phone was switched off or out of coverage and the SMSC exhausted all retry attempts.
The message could not be delivered due to an inactive, unidentified, or untraceable destination number, or because the handset's inbox was full.
⏳ PENDING
The iSMS server has accepted your message and it is queued for submission to the carrier network operator. It has not yet been sent to the SMSC.
⛔ FAIL
The message was rejected at the carrier's SMSC — this occurs when the destination network is unavailable or blocked to the carrier.
