SMPP (or Short Message Peer-to-Peer) is a protocol used for exchanging SMS messages between Short Message Service Centers (SMSCs) and applications. It enables fast, reliable delivery of SMS messages and provides a range of features for managing message traffic and monitoring delivery status.

Navixy supports SMPP v. 3.4 as a means of sending and receiving SMS messages. With SMPP, Navixy can handle large volumes of SMS traffic and offer advanced features such as message batching, message status tracking, and more.

By configuring an SMS gateway in the 'sms_gates' table of the 'google' database, you can connect Navixy to an external SMS center and utilize its messaging capabilities within Navixy platform.
