Introduction

The Inetlab SMPP library implements SMPP protocol for two-way SMS messaging over TCP/IP. It allows to communicate with the SMSC (Short Message Service Center) or SMS provider. Using the library, you can send SMS messages to customers, receive messages from mobile devices and process delivery receipts. It supports long text messages in any encoding.

This is a robust SMPP framework for building production-grade solutions. Inetlab SMPP is helpful in such tasks as:

• notifying users
• command receiving from mobile subscribers (i.e. accounts balance requests)
• creation of SMS Gateway for SMS traffic reselling
• and many other applications.

The Inetlab SMPP library is fully compliant with SMPP specifications v3.3, v3.4, v5.0 and comes with a comprehensive set of code samples.
