SMPP error codes
Our mobile phones sometimes inform us that a text message hasn’t been delivered and it will retry later. It can be frustrating, but now imagine the problem for an enterprise sending hundreds, thousands or millions of messages to their customers. A frustration now becomes a significant business challenge.
The following lists the error messages generated by the Local Mail SMPP. These error codes are included in both intermediate and final delivery notifications. For further information about these error codes and vocabulary, please refer to the GSM protocol specification.

Content Restrictions

Many countries enforce different types of content restrictions on network operators. For example, in India, companies must register their Content and Consent Templates on the DLT. Japan does not allow you to add URLs in the message body.

Time restriction on promotional SMS

SMS campaigns are one of the best ways to promote your products. However, there are time restrictions enforced by various countries.
For example, in India, if you run a campaign outside the permitted hours of 9:00 PM to 9:00 AM then, the SMS campaign shows as failed or message undelivered.

Other reasons for SMS message Failure

Below are some of the other reasons:
  • Exception Time Out
  • Message Inbox memory is full on your mobile device (Lack of space in the receiver's Mobile internal memory for new messages).
  • The number is out of reach (not reachable or out of coverage area).
  • Handset failure(The receiver handset is damaged or is not working properly).
  • Network failure (The carrier network is facing some technical difficulties and messages are just not able to be delivered. (Downtime caused by network problems, Security failure, Hardware failure, etc.).
