What is the new RCS pricing from September 1, 2026? +
From 1 September 2026, RCS message rates move to a clearer two-tier structure: transactional RCS messages (OTPs, order and delivery updates) at approximately ₹0.11 per message, and promotional RCS messages (offers, campaigns, rich cards) at approximately ₹0.30 per message, both plus applicable GST.
Why are RCS prices increasing in 2026? +
The increase largely tracks carrier-level RCS costs — Airtel, for instance, has priced RCS messages at around ₹0.11 per message under its revenue-sharing agreement with Google — plus the added infrastructure cost of carrier-level spam filtering and verified sender programs rolled out across Jio, Airtel and Vi through 2026.
What counts as a transactional RCS message versus a promotional one? +
Transactional RCS covers OTPs, order confirmations, delivery updates and account alerts sent to an existing customer. Promotional RCS covers offers, campaigns, rich cards and carousels used for marketing and engagement — billing treats the two categories differently, similar to SMS and WhatsApp template categories.
Is RCS still cheaper than WhatsApp Business API? +
For OTP and transactional use, RCS at approximately ₹0.11 per message is close to WhatsApp's Authentication/Utility rate of ₹0.1150 per message. For promotional campaigns, RCS at approximately ₹0.30 is meaningfully cheaper than WhatsApp Marketing at ₹0.8631 per message, both plus GST.
Does RCS still fall back to SMS if a device doesn't support it? +
Yes. A correctly configured RCS send automatically falls back to SMS when the recipient's device or network doesn't support RCS, so reach isn't affected by the pricing change — only the per-message cost on RCS-capable deliveries.
How can I reduce my RCS costs after the September 2026 hike? +
Tag every send correctly as Transactional or Promotional so it bills at the right rate, keep transactional templates lightweight rather than rich-card format, reserve promotional RCS for high-intent campaigns, and set category-wise budget alerts in your CPaaS dashboard.
