SMSC Simulator for Windows

The SMSC Simulator is a service for near-to-live testing of your SMPP applications without need of access to real SMSC. The application behaves as a real SMSC with SMPP interface, your application can bind to it, submit_sm, deliver_sm, unbind, however nothing will get delivered anywhere as all the responses are only made-up by the Simulator. It also supports multiple connections but the authentication information is ignored.

The Mobile Server is a simulator, since the SMSC Simulator can't send real short message to mobile user, so it will forward short message between SMSC and mobile phone simulator.
