FAQ

Common questions about Bulk SMS.

Bulk SMS is the practice of sending large volumes of text messages simultaneously to hundreds or millions of recipients. MDS connects directly to telecom operators' networks via SMPP, ensuring high delivery rates and speeds. You provide a contact list and message content; our platform handles routing, DND filtering, and delivery confirmation.

Promotional SMS is used for marketing campaigns (offers, sales, events) and can only be sent between 9 AM and 9 PM to non-DND numbers. Transactional SMS contains service information (OTPs, order updates, alerts) and can be delivered 24/7 including to DND-registered numbers, as it's exempt from DND regulations.

OTP and transactional messages are delivered within 3–5 seconds via our priority routes. Promotional campaigns are delivered at 1–2 million messages per hour. Delivery speed depends on the telecom operator's network but MDS maintains direct connections with all major Indian carriers for optimal throughput.

Yes. MDS is fully TRAI-compliant and registered as a telemarketer (TM) under the TCCCPR 2018 regulations. We handle PE/TM registration, DLT onboarding, Sender ID registration, and message template approval — ensuring every message you send is legally compliant and carrier-approved.

Absolutely. MDS provides a well-documented REST API with SDKs for Python, Java, Node.js, and PHP. We also offer ready-made plugins and connectors for Salesforce, Zoho CRM, HubSpot, WooCommerce, Shopify, and other major platforms. Most integrations go live within a few hours.

Most clients are live within 24–48 hours for OTP/transactional SMS. Promotional campaigns require DLT template registration which takes 1–3 business days. MDS provides dedicated onboarding support, including Sender ID setup, DLT registration, and API testing — so you're sending within a working day of sign-up for urgent use cases.
