SMPP error codes

On your SMPP links the following error codes can be returned by your SMS service provider. Please check the meaning and the possible resolution in the table bellow.

The error messages are displayed in the following format: Status_RoutingCode_ErrorCode

  • Your message has been sent to the telephone operator and is waiting to be delivered
  • Sending is underway by the telephone operator
  • The recipient's terminal may be switched off or unreachable and the service provider is attempting to send
  • Your message has been sent to a number of a telephone operator for which there are no return receipts. In this case the message will always be queued even after the actual delivery

Below are the descriptions of the codes returned in case of error.

Status

The possible values are

  • NACK: request immediately rejected by the SMSC operator
  • UNDELIV: the message can not be delivered
  • EXPIRED: it was not possible to deliver the message and the period of validity's period has expired
  • UNKNOWN: Message is in an invalid state
  • FAILED: The message can not be delivered

Note: For the protocol used, there is also the state DELIVRD (message delivered) but this will never be displayed, because it does not fall into the error's examples

Routing Code

Depending on the route (SMSC) which is sent a SMS error the code may be different. The possible paths are identified by numbers (1, 2, 3, ...)

ID SMSC ID
1 MO

Error Code

Error code depends on the status and in some cases also by the RoutingCode

Immediate errors (Status = NACK)

For errors like "NACK" they depend on messages belonging to the 0x00000400-0x000004FF interval. The first table shows errors are independent by the route, while the following tables report dependencies to the SMSC on which the message was routed.
