What Is RCS Messaging? A Plain Guide for Indian Businesses

What RCS messaging actually is

RCS stands for Rich Communication Services. Think of it as SMS rebuilt for smartphones. The message still arrives in the phone's normal messaging app, but instead of 160 characters of plain text, you can send images, short videos, a swipeable carousel of cards and buttons people can tap.

For businesses, the version that matters is RCS Business Messaging (RBM). Here the sender is a verified business "agent" with its name, logo and brand colour shown at the top of the chat. In India, most RCS business traffic reaches Android users through Google Messages, which is the default SMS app on a large share of Android phones.

How RCS is different from SMS and WhatsApp

• Versus SMS: SMS is text only and shows a six-character header. RCS shows your brand, supports media and buttons, and gives read-style engagement signals such as delivered and clicked.
• Versus WhatsApp: WhatsApp needs the person to have WhatsApp and you to use approved templates. RCS needs no extra app but depends on the handset and network supporting it. iPhones and older phones may not receive RCS business messages, so a fallback is important.

Many businesses use both. We explain the trade-offs in more detail in WhatsApp vs RCS and RCS vs SMS.

What you can send with RCS

• Rich cards: one image or video with a title, description and buttons.
• Carousels: several cards people can swipe through, useful for courses, doctors, loan products or property listings.
• Suggested replies and actions: buttons like "Call counsellor", "Open map", "Visit website" or "Interested".
• Plain text with branding: even a simple text message looks more trustworthy when it comes from a verified agent.

How it works, step by step

Getting started is simpler than most people expect, but there are a few steps.

• 1. Agent creation: your provider creates an RBM agent with your brand name, logo, colour, description, website and contact number.
• 2. Verification and launch: the brand details are reviewed and the agent is launched for messaging. Timelines vary, so plan a little buffer before a campaign.
• 3. Templates and content: you prepare the cards, carousels and buttons for your campaign.
• 4. Capability check: before sending, the platform checks which numbers can receive RCS. Numbers that cannot are routed to SMS or another channel.
• 5. Reporting: you see delivery, read and click data and can follow up with the people who engaged.

What does RCS cost in India?

RCS is usually billed per message, and the rate depends on the message type (basic text versus rich media) and your provider. Prices change, so please check current rates on our pricing page or ask for a quote rather than relying on old figures you find online.

A useful way to think about cost is not "price per message" but "price per interested person". Sending a rich carousel to everyone on a list can be wasteful. Sending it to the people who already showed some interest is far more efficient.

Where RCS works well

• Education: course carousels, campus video, open day invites and fee reminders.
• Healthcare: doctor profiles, health check packages and appointment reminders with a "Book" button.
• Finance: loan or insurance product cards with a "Call me back" button.
• Reaching DND numbers: RCS can be an option for reaching people who did not receive other channels, subject to your consent and compliance obligations.

How RCS fits into a multi-channel campaign

RCS is strongest as part of a sequence rather than on its own. In the Smart Growth AI Campaign, a voice call goes out first and the system tracks how long each person listened. People who listened for 10 to 25 seconds, the "partially interested" group, receive an RCS carousel with up to 10 image or video cards. People who listened longer get a WhatsApp template, and anyone RCS cannot reach gets an SMS fallback. That way the richer, paid message goes only to people who showed some interest.

Common mistakes to avoid

• Sending RCS without an SMS fallback, so non-RCS phones get nothing.
• Overloading a card with text. Keep titles short and let the image do the work.
• Using unclear buttons. "Talk to a counsellor" is better than "Click here".
• Ignoring opt-outs. Every channel, RCS included, needs a clear way to stop messages.
