Short Message Peer-to-Peer (SMPP)

What is SMPP?

SMPP stands for Short Message Peer-to-Peer, and is an open, industry-standard telecommunications protocol used to exchange SMS messages between Short Message Service Centers (SMSC). 

What’s the SMPP protocol?

The SMPP protocol is a level-7 TCP/IP protocol, so mobile applications can transfer short message data between External Short Message Entities, Routing Entities, and Message Centers. To do this, applications use an SMPP connection to an SMSC, SMS gateway, or SMPP gateway.

There are three different types of the SMPP protocol:

• v3.3: The original public version of SMPP protocol was released in 1997.
• v3.4: The second public version was released in 1999.
• v5: The final version was released in 2003. 

How Bandwidth is involved with SMPP
