# Can I test DLT SMS compliance in the Sandbox Account?

Yes, but it’s limited. The Sandbox at https://unify.smsgateway.center supports basic SMS testing, including DLT-compliant templates. Full DLT SMS features (e.g., custom headers, bulk sends) require a paid account and operator registration. Use the Sandbox to start, then check our [DLT SMS guide](https://www.smsgatewaycenter.com/dlt-sms/) to scale up to compliant messaging.
