Rich Communication Services (RCS) is the modern successor to SMS. Instead of plain text from a short header, customers see your brand name, logo and a verification mark, with images, carousels and tap-to-act buttons such as "Track order", "Pay now" or "Book a slot". It arrives in the phone's default messaging app, usually Google Messages on Android, so customers do not need to install anything.
In India, interest in RCS has grown as operators and Google have worked on safer business messaging. In March 2026, Airtel and Google announced a collaboration to bring RCS messaging with telco-backed sender checks, DND-aware categorisation and spam filtering to Airtel users. This guide explains what that means for businesses and how to decide whether RCS is worth adding to your mix.
How RCS business messaging works
RCS business messaging (often called RBM when delivered through Google's platform) works like this:
- Your business creates an RCS agent, which is your branded sender profile with name, logo, description, colours and contact details.
- The agent goes through brand verification, so customers see a verified sender rather than an unknown number.
- The agent is launched on carriers, which approve it for delivery to their subscribers.
- Your platform sends messages to customers whose phones and networks support RCS. For customers without RCS, messages can fall back to SMS.
Because RCS depends on the customer's device, messaging app and operator, reach varies. Your provider should give you a capability check that tells you which numbers on your list can receive RCS before you send.
What you can send with RCS
- Rich cards with an image, title, description and buttons
- Carousels of several cards, for example product ranges or property listings
- Suggested replies such as "Yes, confirm" or "Reschedule" that customers tap instead of typing
- Suggested actions such as open a URL, dial a number, open a map location or add a calendar event
- Longer text without the 160-character segment limit of SMS
Typical uses in India include order and delivery updates with tracking buttons, appointment reminders with confirm/reschedule options, bill and EMI reminders with payment links, event and admission campaigns for coaching institutes and colleges, product launches for retail and automobiles, and property showcases for real estate developers.
How RCS fits with DLT and TRAI rules
RCS is not the same as SMS, but it is still commercial communication to Indian telecom subscribers, and the ecosystem is designed to respect TRAI's consumer protections. The Airtel and Google announcement, for example, says the platform validates sender identity using telco-backed checks, respects DND preferences by categorising communications as promotional or transactional, and blocks spam. In practice:
- Treat promotional RCS like promotional SMS: send only to customers who have not opted out, within sensible hours, with a clear way to stop.
- Keep your SMS fallback compliant. Fallback messages are ordinary SMS, so they need DLT-registered headers, templates and whitelisted links. See our DLT registration guide.
- Follow the Digital Personal Data Protection Act, 2023 for consent and data handling; see our DPDP guide for marketers.
The precise rules for RCS in India can vary by operator and platform and may evolve, so ask your provider to confirm the current requirements for your category of message. Our India RCS compliance page summarises the main points.
RCS vs SMS vs WhatsApp in India
| Factor | SMS | RCS | WhatsApp Business Platform |
|---|---|---|---|
| Reach | Every mobile phone | Android phones and networks with RCS support; varies by operator and device | Customers who use WhatsApp and have opted in |
| Branding | Header only (with -P/-S/-T/-G suffix) | Brand name, logo, verified sender | Business name, profile and verification options |
| Rich media and buttons | No | Yes | Yes |
| App needed | No | No, uses default messaging app | WhatsApp app |
| Registration | DLT entity, headers, templates | Agent creation, brand verification, carrier launch | Meta business portfolio, WABA, templates |
| Two-way conversations | Limited | Yes | Yes, very strong |
RCS is not a replacement for WhatsApp in India, where WhatsApp conversations are deeply established. It is most useful when you want rich, branded messages in the native inbox, especially for customers you reach by phone number without a WhatsApp opt-in history, with automatic SMS fallback so nobody misses critical updates.
What RCS costs
RCS pricing in India depends on the platform, operator and message type. Some providers charge per message, some per conversation or session, and fallback SMS is charged at SMS rates. Ask for:
- The rate for RCS messages (basic text and rich messages may be priced differently)
- How fallback SMS is charged
- Any setup or agent verification fees
- Whether you pay for messages that are not delivered
For a framework to judge whether RCS pays back, see our RCS cost and ROI guide.
How to launch RCS in India: a checklist
- Pick a use case with clear value, such as delivery updates or payment reminders, rather than starting with mass promotions.
- Prepare brand assets: logo, banner image, brand colours, short description, website, privacy policy and contact details.
- Create the agent through your provider and submit it for brand verification.
- Get carrier approval for launch; timings vary by operator.
- Design messages with a clear primary button and a short headline; test on several Android devices.
- Set up SMS fallback with DLT-approved templates.
- Run a capability check on your list to see RCS reach.
- Start small, measure delivery, read and click rates, and compare with SMS before scaling.
Mistakes to avoid
- Overloading cards with long text and many buttons; one clear action works best.
- Skipping fallback, which leaves customers on non-RCS devices without the message.
- Using RCS to send unwanted promotions. RCS is designed with spam controls; poor-quality campaigns risk throttling and harm brand trust.
- Ignoring iPhone users. RCS business messaging reach on iPhones depends on carrier and platform support, so plan your channel mix accordingly.
Measuring RCS results
RCS gives richer reporting than SMS. Depending on your platform, you can see delivery, read receipts, button taps and replies. Use these to compare RCS with SMS on the same use case:
- Delivery rate across operators and devices, including how many messages fell back to SMS
- Read rate, which SMS cannot measure
- Click or tap rate on suggested actions
- Outcome, such as payments completed, bookings confirmed or orders tracked
A fair test sends the same message to comparable groups by RCS and by SMS, then compares cost per outcome rather than cost per message. If RCS lifts payments or bookings enough to cover any price difference, expand it to more use cases.
