SMS pricing looks simple on paper, a cost per message, but the real number depends on several separate line items. Here's what actually goes into bulk SMS pricing in India.
Per-Message Cost
Bulk SMS in India typically runs in the paise-per-message range depending on volume, route (transactional vs promotional), and provider. High-volume senders negotiate lower per-message rates, while low-volume or ad-hoc campaigns pay closer to list price.
Lowest per-message cost comes from committed volume, not from switching providers alone.
DLT Registration Costs
Before sending any bulk SMS legally, businesses must complete TRAI's DLT registration: entity registration (a one-time fee), sender ID/header registration, and template registration (usually free but time-consuming to get approved). Budget for this as a one-time setup cost, not a per-message one.
Promotional vs Transactional Pricing
Transactional SMS (OTPs, confirmations, alerts) is usually priced at a premium per message compared to promotional SMS, since it carries stricter delivery guarantees and bypasses DND. Promotional SMS is generally cheaper per message but restricted to a 9 AM-9 PM window and blocked to DND numbers. See our full breakdown of promotional vs transactional SMS.
Hidden Costs to Watch For
Some providers bundle in extras that change the effective cost: multi-part message splitting (a message over 160 characters counts as multiple SMS), unicode or regional-language messages (which have a much lower character limit per segment), and minimum monthly commitments. Choose a provider that's transparent about these before you sign, not after your first bill.
Frequently Asked Questions
Is there a free trial or minimum order for bulk SMS?
Most providers, including RR Media, offer small test batches before you commit to a larger campaign, ask before signing any minimum-volume contract.
Does SMS pricing vary by state or city within India?
No. SMS routing costs are largely uniform across India regardless of the recipient's state, unlike some voice call pricing which can vary by circle.
