How to Manage Throttling with SMPP


Managing throttling in SMPP.

Applies To

  • SMPP
  • Maximum Throughput


By default, an SMPP account is set up with a throughput of 30 SMS per second.

A logic of flow-control is needed by the SMPP client in order to avoid rejections of SMS with error code 0x00000058 (throttling error, 88 decimal value).

Here is the recommended logic:

  1. Perform a throttle control that is matching the authorized throughput (30 SMS/sec by default).
  2. Resubmit rejected submit_sm with error code 0x00000058.
