When you sign up online for an account with Sinch you will be given some test credit to allow you to start sending messages immediately. You can use this credit to test the service we provide. Sign up for your account to get started.
See our SMS channel Getting started guide on our developer documentation site for more information.
If you would like to get in touch to discuss testing the system for a potentially large account, please contact Sinch. This is something we can look at on a case-by-case basis, but as a general rule, once the test credit is used up you will need to pay for all further messages sent.
