SMS Fallback must comply with India's DLT framework requiring sender ID registration and template approvals for text messages. While WhatsApp bypasses DLT, the SMS Fallback component needs pre approved templates to function legally without operator blocking. Professional providers like Anantya.ai handle DLT compliance automatically, maintaining updated registrations across all telecom operators. The system ensures SMS Fallback messages use approved formats preventing delivery failures from regulatory issues. Businesses avoid penalties and blacklisting by implementing compliant solutions from the start. Audit requirements demand complete delivery logs which SMS Fallback systems provide automatically for both channels used. Contact now!
