To enable sandbox access for certain DLT message templates:
- Go to Sidebar Menu ⇾ SMS ⇾ Message Templates.
- Review the list of existing templates (create a new one if none exist by clicking Add).
- In the Allow Sandbox column, use the dropdown to select Allow for the templates you want to make available.
- Once set, those templates will be activated for sandbox testing and can be used by new sandbox users.

👉 This ensures resellers control which approved DLT templates are available for testing in the sandbox.
