Shared, dedicated, AWS and on-premises

Most teams start on the shared simulator (USD 75). Use a dedicated instance for load tests, custom DLRs or isolation. AWS Marketplace keeps traffic in your VPC. On-premises is for air-gapped hosts. Part of Melrose Labs SMPP Testing.

The Shared SMSC Simulator service allows message submissions via an SMPP account at rates up to 100 SMS per second. It returns delivery receipts in a standard format with a “delivered” status for all messages. This shared simulator is non-customisable and does not offer monitoring capabilities. It supports both Mobile Originated (MO) and Mobile Terminated (MT) SMS.

SMPP over TLS support is available for SMS applications to connect securely (SMPP TLS port: 8775).

Dedicated SMSC Simulator instances are available for clients requiring advanced testing capabilities beyond the shared service. These instances support up to 8,000 SMS per second, accommodate up to 250 SMPP binds per IP, and allow an unlimited number of SMPP credentials. They also offer SMPP v5 flow control, congestion avoidance, and configurable delivery receipts (status, latency, format). The specific capabilities and configurations can be tailored to meet your requirements.

SMPP over TLS, performance monitoring using Prometheus/Grafana, dedicated capacity and CDRs are supported. Instances are available at our London, Frankfurt, Stockholm, Cape Town, Hong Kong, Singapore, Sydney, North Virginia, Ohio and São Paulo locations.
