6 RCS for Business features


  • Text Messages & Links
  • Rich Card
  • Rich Card with Multiple CTAs
  • Carousel (Multiple Rich Cards)
  • Suggested Replies (Quick Replies)
  • Verified Branding


Text Messages and Links.

You still need fast alerts like OTPs or delivery updates. RCS handles them with the speed of a text but adds the crucial layer of verified branding. This means your urgent updates land in a trusted, professional window. Any link is clearly visible, clickable, and trackable, ensuring high efficiency for every transactional message.


Rich Card


RCS Rich Card

Why describe an event or a product when you can show it? The Rich Card is your chance to use high-resolution media (an image or video) to grab attention. It provides clear context and funnels the customer into the next step using one or two key action buttons. Use it to confirm an order, show a tracking map, or pitch a single, hot new deal.


Rich Card with Multiple CTAs

Don't make customers dig for options. This card allows you to include all the relevant next steps right under your visual. You get up to five buttons that anticipate the customer's needs. Use it for complex situations like a billing notice that offers "Pay Now," "View Details," "Call Support," and "Request Payment Extension." You streamline the process, making every interaction effortless.


Carousels

See how RCS carousel messages deliver rich product suggestions directly in chat.



This is your mobile catalogue. Instead of linking out to a website, the Carousel lets customers scroll through multiple offerings, up to ten cards directly within the message. Each card has its own picture and buttons. It’s perfect for abandoned cart recovery, showing different travel options, or promoting a new product line. You create an immersive shopping experience right in their inbox.


Suggested Replies (Quick Replies)

Suggested Replies are the pre-written, tappable bubbles that give customers instant, easy answers like "Yes," "No," or "Check My Account." Every tap sends instant data to your system, allowing for blazing-fast automation and resolution. It removes all friction and makes talking to your brand feel natural and instantaneous.


Verified Branding

Every message you send will be instantly recognizable. We replace that generic phone number with your official logo, your brand name, and a verified checkmark. This isn't just a detail—it's your frontline defense against phishing and spam. When customers see that verified profile, they feel safe, and they open your message. It’s immediate, brand-building trust delivered directly to their inbox.


iPhone and Android now connect the same way. Your brand should too.

Frequently Asked Questions (FAQs)


Is RCS for Business officially supported on iPhones in India?

Yes, RCS for Business (RCS-B) is officially supported on all Apple devices in India running iOS 18 or later. The full B2B launch went live on October 28, 2024, marking a critical expansion of the channel's reach.

What is the key difference between P2P RCS and RCS for Business on iPhone?

The main difference for Indian brands is the user experience. Unlike person-to-person (P2P) RCS, RCS for Business (RCS-B) requires no action from the end-user to receive rich, interactive B2B messages. RCS-B messages are received by default, making adoption seamless for companies targeting iPhone users.

Which Indian carriers support iPhone RCS Business Messaging?

The initial rollout for iPhone RCS Business Messaging in India is primarily driven by carriers with robust RCS network infrastructure. This includes Reliance Jio and Airtel. Users on these networks with compatible Apple devices (iOS 18+) can receive rich RCS-B messages.

How much does RCS for Business cost compared to SMS in India?

RCS for Business is a premium A2P channel and is typically priced higher than standard SMS. The pricing model is often based on a per-event fee (e.g., per delivered message or per conversation session). However, the return on investment (ROI) is significantly higher due to improved conversion rates, higher engagement, and enhanced customer trust.

How can Indian businesses start sending RCS messages to iPhone users?

To start sending RCS messages, Indian businesses must partner with a certified RCS Business Messaging Provider (RBP), also known as a CPaaS partner. This provider handles the complex technical integration with carrier networks (Jio and Airtel), manages brand verification, and ensures your message templates adhere to the global RCS standards for universal reach.

Is RCS a free replacement for SMS in the Indian market?

No, RCS for Business is not a free channel. While personal (P2P) RCS messaging may be free for end-users, the commercial Application-to-Person (A2P) RCS Business Messaging utilizes a paid pricing structure, similar to SMS, but offers vastly superior value through rich media, branding, and analytics.

Does a brand need a separate channel to reach iPhone users with RCS?

No. One of the core benefits of RCS for Business is the Universal Rich Reach. Brands can deploy a single, rich message template that reliably reaches the native message inbox of both Android and iPhone users without requiring separate platforms or integrations.

What happens if an iPhone user's device or carrier doesn't support RCS?

RCS for Business utilizes a Smart Fallback Mechanism. If the end-user does not have an RCS-enabled device or is not on a supporting carrier, the rich message automatically and reliably falls back to a standard, plain-text SMS. This ensures 100% message delivery.

How does RCS for Business prevent fraud and improve customer trust?

RCS-B significantly improves security through Verified Sender Status. Messages arrive with the brand's verified name and logo, often including a security checkmark, which makes it much harder for phishing attempts to mimic a legitimate business's communication.
