For decades, SMS has been the workhorse of business communication in India: 160 characters, plain text, no branding. RCS, or Rich Communication Services, changes that. It turns the default messaging app on Android into a rich, branded, interactive channel that looks and feels like a modern chat experience while keeping the universal reach that made SMS so powerful. For Indian brands competing for attention, RCS is quickly becoming a channel worth understanding.
What exactly is RCS?
RCS is an upgraded messaging protocol that succeeds SMS and MMS. Instead of a plain text bubble, RCS supports verified sender identity, high-resolution images and video, action buttons, suggested replies, read receipts and typing indicators. On Android, RCS is delivered through the native Messages app, so customers do not need to download a separate application. They simply receive a richer message in the same place they already read texts. Our RCS messaging service helps brands launch on this channel with verified identity from day one.
Verified branded messaging builds trust
One of the most valuable features of RCS for business is verification. A registered brand gets a verified sender profile, complete with your business name, logo, brand colour and a verification checkmark. Instead of a message arriving from an anonymous numeric sender or a six-character header, customers see your actual brand identity confirmed by the platform. In a market where SMS phishing and spoofed senders are a constant concern, this verified presence dramatically increases trust and the likelihood that customers act on your message.
Rich cards and carousels
RCS lets you move beyond text. Two formats stand out:
- Rich cards: a single card combining an image or video, a title, descriptive text and tappable buttons. Perfect for a product launch, an appointment confirmation with a reschedule button, or a delivery update with a track-order action.
- Carousels: a horizontally scrollable set of cards, ideal for showcasing several products, plans or offers in one message so customers can browse and tap without leaving the chat.
Add suggested actions like Call Now, Visit Store, View Offer or Pay, and you turn a one-way notification into an interactive journey that can complete a transaction inside the messaging thread.
RCS vs SMS: how they compare
RCS does not replace SMS overnight; the two work together. Here is how they differ:
- Content: SMS is plain text up to 160 characters per part. RCS supports images, video, cards, carousels and buttons.
- Branding: SMS shows a header or number. RCS shows a verified brand profile with logo and colours.
- Interactivity: SMS relies on links. RCS offers tappable replies and actions inside the message.
- Insights: SMS gives delivery reports. RCS adds read receipts and engagement signals.
- Reach: SMS reaches every phone. RCS reaches RCS-enabled Android devices, with SMS as a fallback when RCS is unavailable.
The smart strategy is RCS-first with automatic SMS fallback. Customers on capable devices get the rich experience, while everyone else still receives the message as bulk SMS, so you never sacrifice reach.
Why adoption matters in India now
India is overwhelmingly an Android market, and the native Messages app ships with RCS support on a large and growing share of devices. That gives Indian brands an unusually large addressable audience for RCS compared with markets dominated by other platforms. As more handsets and carriers enable RCS by default, early adopters build verified brand recognition and richer engagement habits before the channel becomes crowded. Brands that wait risk arriving late to a channel their customers already use.
Where RCS delivers the most value
RCS shines wherever a richer, two-way experience helps. Think order confirmations with live tracking, appointment reminders with one-tap rescheduling, product catalogues delivered as carousels, boarding passes and tickets with visual detail, and customer support that resolves queries inside the chat. It pairs naturally with other channels too, complementing transactional OTP SMS and outreach campaigns. Explore the full set of options on our services page to design a multi-channel mix.
Frequently Asked Questions
Do customers need a special app to receive RCS?
No. On Android, RCS is delivered inside the default Messages app, so customers receive rich messages in the same place they read SMS, with no extra download required.
What happens if a user's device does not support RCS?
A well-configured RCS campaign falls back to SMS automatically. RCS-capable users get the rich experience, while everyone else still receives your message as a standard text, preserving full reach.
Is RCS more trustworthy than SMS?
Yes. RCS uses verified sender profiles with your brand name, logo and a verification mark, which makes it much harder to spoof than a plain SMS header and helps customers trust the message.
What kind of content can I send over RCS?
You can send images, video, rich cards, scrollable carousels, suggested replies and action buttons such as Call Now or View Offer, turning notifications into interactive experiences.
