3. Connect and send

Prepare eligible contacts, integrate your API or dashboard workflow and review available delivery reporting.

India compliance essentials

DLT registration, approved sender IDs and SMS templates

For business messaging in India, the required DLT registration, header approvals, template approvals and customer consent or preferences depend on the message category. GreenAds assists with the onboarding process; operators control approval and any separate registration fees.

01 · Register your business

Complete applicable entity registration through a recognized telecom DLT portal.

02 · Approve sender and content

Submit the correct header, SMS template and any required consent template for review.

03 · Send permitted messages

Use the approved category and content while respecting user preferences, DND rules and delivery time restrictions.

i

Important for promotional campaigns

Promotional SMS is subject to TRAI rules and preferences. Claims of bypassing DND lists or guaranteeing delivery should not be treated as compliant messaging practices.

Sources & methodology

Pricing, calculations and compliance

Published 2026 SMS pack prices were taken from GreenAds' existing SMS pricing page. GST calculations use the page's listed 18% rate. Segment estimates use common GSM/Unicode single and concatenated message lengths; exact credit charging can depend on encoding and gateway handling. India DLT and promotional messaging requirements should be verified against the applicable TRAI sender registration guidance and current commercial communications regulations and operator guidelines. Do not interpret this guide as a binding price quotation or legal advice.
