# What happens if I don’t register my PE for DLT SMS?

Without registering your Principal Entity (PE) for **DLT SMS**, your SMS will be blocked by Indian operators under TRAI’s TCCCPR 2018 rules. Unregistered entities can’t send messages via our **SMS gateway** at https://unify.smsgateway.center—you’ll need a PE ID, headers, and templates approved on a DLT portal (e.g., Airtel, Jio). Start registration today at [unify.smsgateway.center/signup/](https://unify.smsgateway.center/signup/) to stay compliant and keep messaging seamless.
