What Ozeki SMS Gateway is
Ozeki SMS Gateway is on-premises software for businesses that need to send and receive SMS, automate messaging, or offer SMS services to customers. It connects with modems, Android phones, and telecom or messaging interfaces including SMPP, UCP/EMI, CIMD2, OZX, HTTP/REST, SIP, and Modbus/SNMP. Routing options include least-cost and backup routing, load balancing, message copying, and modification. Applications can connect through REST, SOAP, JSON, WebSocket, language SDKs, SQL polling, databases, spreadsheets, files, email, and FTP. The gateway supports reporting databases including Microsoft SQL Server, Oracle, MySQL, PostgreSQL, and SQLite. Security features include HTTPS, TLS/SSL for supported protocols, encrypted password storage, and logging that can hide phone numbers and message text. It can run on servers, cloud platforms, or Android phones. A free trial is available, but there is no free plan; licenses are one-time purchases and SMS provider charges may apply. Listed plans range from €1,490, paid once to €79,990, paid once. Ozeki Ltd. is based in Debrecen, Hungary, and was established in 2000.
