The Tyr SMS Gateway can be used for sending high volumes of SMS messaging quickly and reliably to mobile users. The SMPP API is well-suited to this use; however, we also provide our quick and easy to use REST SMS API that can be equally suitable.


Short Message Peer-to-Peer (SMPP) is a standard API used by applications to send and receive SMS. It provides the highest level of control and is suitable for low or high volumes of SMS. SMPP v3.3, v3.4 and v5 are supported, and TLS can be used to secure the session between your application and the Tyr SMS Gateway.

Virtual SIM Hosting

Virtual SIM Hosting (VSIM) provides a high performance method of receiving up to 200 SMS per second through a customer-supplied SIM. The mobile number of the SIM can be used to receive SMS without the restrictions of normal SIM card hosting. This service is a means of getting the performance of Virtual Mobile Numbers (VMNs) with the advantage of a national mobile number (e.g. a SIM from a mobile network in France for use with a service targeted at mobile users in France).

Virtual Mobile Numbers

Virtual Mobile Numbers (VMNs) bring high performance with low delivery latency of messages from mobiles to applications. A single Virtual Mobile Number allows an application to receive incoming SMS from all supported networks worldwide. The Virtual Mobile Numbers behave in the same way as a regular mobile number, but with the benefit of significantly higher throughput (200 SMS per second) to your application.
