Delivery Report Interpretation

Overview

If messages are sent with delivery reports enabled (and the networks concerned support reports) then delivery reports will be added to the online billing system automatically. Delivery reports can also be routed to an HTTP URL or SOAP RPC endpoint of your choosing or via your SMPP connection.

The status codes returned in the delivery reports can be interpreted in several ways depending upon the type of SMS sent:

All SMSs

Status	Description
DELIVERED	SMS delivered to handset
FAILED	SMS delivery has failed
BUFFERED	Mobile Network is continuing delivery attempts of the SMS, however delivery has not been successful yet. This will continue throughout the validity period of the SMS, assuming the message has not yet been DELIVERED or FAILED
REJECTED	Mobile Network has rejected the SMS, and delivery has not been attempted

SMS sent through a Bulk SMS account

Status	Description
DELIVERED	SMS delivered to handset
FAILED	Immediately: Bad number, unable to route
	After Validity Period: Out of coverage, SIM full, turned off for the duration of the validity period
REJECTED	User barred, Invalid SMS
NONE/BUFFERED	Out of coverage, phone turned off and operator retrying for duration of validity period
