Our Short Message Peer to Peer (SMPP) protocol interface supports both version 3.3 and 3.4, is typically used by high volume BULK SMS content providers.

The SMPP Protocol is typically used as a bulk messaging solution. Registered clients may bind directly with our service using SMPP version 3.3 or 3.4 either via a direct dedicated connection or over the Internet. SMPP is a binary-based protocol that requires an external application (SMPP client) to initiate a login (or 'bind') sequence with password-based authentication before accepting any messaging commands from that system.

Application developers can makes use of SMPP from within their programs using one of the many SMPP SDK and toolkits that are for Java, C/C++, Perl, VB and other languages. For more information on SMPP please visit www.smsforum.com
