Melrose Labs operates SMSC simulators (aka SMPP server simulators) and Dedicated SMSC Simulators for use in the development and testing of SMS text messaging capabilities within applications. They simulate SMSCs (short message service centres) and SMPP SMS gateways, and simulate SMS message delivery. SMPP v3.3, SMPP v3.4 and SMPP v5 using TLS and non-TLS connections are supported.

Applications send SMS messages to mobiles by submitting messages to the SMSC Simulator service using SMPP. The SMSC simulators simulate the delivery of the messages, including the generation of delivery receipts back to the application. SMS messages from mobile numbers can also be submitted and delivered to the SMS application (see Simulate Inbound SMS to your Application).

The SMSC simulators enable you to send SMS messages from your application without messages being delivered to real mobile phones and therefore without any SMS delivery costs. Stress testing of your application can also be performed to show how your application behaves under load and various other scenarios tested before live operation and without affecting production SMSCs. The SMSC simulators can handle high rates of SMS and a large number of simultaneous connections from your application.
