How do I verify SMS delivery in the Sandbox Account?

After sending a test SMS, visit the “Delivery Report” section on https://unify.smsgateway.center. It displays each message’s status—delivered, pending, or failed—with timestamps. This lets you confirm your SMS reached the whitelisted number, mirroring the reliability you’ll get with a paid plan. It’s a key feature of our SMS gateway, ensuring transparency even in testing.
