SendBulkSMS is offering a SMPP server/client license with no speed/throughput limitations or limits for number of SMPP accounts that can be served. It’s a general site license, so you’re allowed to use it on several machines on your side, as long as it’s within your company scope.
This means that you can increase your throughput if you install our software in more servers as it is designed to support load balance and failover.

We provide it under a binary usage license, and currently the system is running at more than 120 customer sites, including GSM wireless network customers doing inter-carrier message exchange with it, but also “simple” SMS aggregators. It handles several dozen million SMS per month on each site.

Some known names include Google SMS services, Clickatell, Dimoco, Telia, Vodafone group, tigo, TIM, HP, Intel, Siemens and various other.

The main features are:

• Supports all message directions, SMS-MT, SMS-MO, DLRs (transparently, with own Msg IDs) using all SMPP PDUs
• Supports even query_sm, replace_sm and delete_sm PDUs
• Session timeout handling like any major vendor SMSC
• Billing/account can be done via postpaid CDR records or prepaid via credit deduction inside mysql, oracle or sqlite3 database
• Alternatively routing and/or accounting can be performed outside of system via HTTP callbacks
• No incense based throughput limitation, you can run as many SMS/sec you want
• No time limitation in license usage
• A modularized plugin API that allows you to call further logic while SMPP PDUs are processed, eg a SPAM plugin that denies specific MTs depending on matched regular expression (regex) patterns of PDU elements, or a “extra HTTP remote” logging plugin.
• The plugin API is public and you can compile your own plugin DSO (dynamic shared object) files into the runtime core of system to perform own logic inside.

We are also providing a full GUI for managing the SMPP server that includes billing modules, 2way SMS and many other features.

Every configuration can be performed easily after installation of the system in your servers.

Every aspect of the system can be handled via the provided GUI.
