SMPP Testing

SMPP compliance and performance testing of SMSCs, SMS gateways and apps.

Short Message Peer-to-Peer (SMPP ) implementation testing shows the level of conformance to the SMPP protocol when sending and receiving SMS messages between applications and mobiles. SMPP testing also determines the implementation's level of performance.

SMS applications (clients) and SMSCs/SMS gateways (servers) can be tested using the SMPP Testing service. Automated and manual testing is used with servers and clients, and covers SMPP v3.3, v3.4 and v5. We provide SMPP testing consultancy services and a number of free-of-charge online services.


Melrose Labs provides a range of SMPP Testing services:

SMS Platform Testing

Testing shows the conformance of an SMSC or SMS Gateway to the SMPP protocol and its performance (e.g. rate of SMS processing).

SMS Platform Testing

SMSCs, SMS Gateways and SMPP Servers

Testing shows the conformance of an SMSC or SMS Gateway to the SMPP protocol and its performance, e.g. rate of SMS processing. SMPP account credentials are used to connect to the SMPP server of the SMSC or SMS Gateway and perform testing.

SMPP tests available:

  • Bind Type and Version Support (SMPP v3.3, v3.4, v5) [example]
  • SMS submission rate (single bind)
  • Delivery receipt support and reception rate
  • Attribute testing (e.g. validity period adherence)
  • SMS load testing (simultaneous binds, SMS load) [example]
  • SMPP operation support

Non-conformance with the SMPP protocol, connection attempt reliability and response timings are also reported.

The SMSC/SMS Gateway Bind Type and Version Support test is publicly available on this page. For all other SMPP implementation testing please contact us for a quote.
