Using in production

Whatever the language or API, you can send RCS and receive RCS between applications and mobiles for a wide range of uses.

We provide a wide range of CPaaS services and infrastructure to organisations, including cloud platforms that enable you to run your own SMS gateway.

Get in contact with us to find out more about CPaaS voice, messaging, video and identity from Melrose Labs.


For testing your application's RCS support when using the MaaP protocol, we recommend starting with the Melrose Labs RCS MaaP Simulator service to simulate RCS messaging to and from mobiles.
