FREQUENTLY ASKED QUESTIONS

Bulk SMS Software FAQs

Answers to common technical, DLT regulatory, API integration, and pricing questions.

How does Render ensure compliance with TRAI DLT regulations in India?
We provide end-to-end guidance for TRAI Distributed Ledger Technology (DLT) compliance. Our platform connects directly with telecom DLT portals (Vilpower, Jio, Airtel) to whitelist your Principal Entity, approved Sender Headers, and Registered Content Templates.
How fast are transactional OTP messages delivered to end users?
Our dedicated OTP tier utilizes direct SS7 operator pipes with multi-telco auto-fallback, achieving an average delivery latency under 2.5 seconds with guaranteed 99.98% delivery success rates.
Can we integrate the SMS gateway into our existing CRM, web, or mobile app?
Yes. We offer developer-friendly HTTP REST APIs, SMPP 3.4 protocols, and SDKs for PHP, Node.js, Python, Java, and C#. Implementation takes under 15 minutes with our copy-paste sample code and sandbox environment.
What is the difference between Promotional, Transactional, and OTP routes?
Promotional routes deliver marketing campaigns between 10 AM and 9 PM to non-DND numbers with numeric sender IDs. Transactional and OTP routes operate 24/7 with 6-character alphabetic headers, delivering critical alerts and login verification codes to all numbers including DND.
How do real-time Delivery Reports (DLR) and analytics work?
Every dispatched message generates real-time operator delivery receipts (Delivered, Undelivered, Failed, Expired). Real-time webhooks send DLR status callbacks directly back to your database servers with timestamp precision.
How quickly can our DLT headers and SMS credits be activated?
If you already possess a registered DLT entity, your account and API credentials can be provisioned in under 2 hours. For new businesses, our Bangalore regulatory support team completes end-to-end DLT registration within 24 to 48 hours.
