What is RCS Business Messaging? The Complete Guide

Your SMS was delivered. But did anyone actually engage with it?  

Traditional SMS tells businesses very little about their customers.

RCS chat changes that by bringing richer content, buttons, suggested replies and other interactive features to the native messaging experience. And this is perfect considering customers are increasingly gravitating towards interactive messaging experiences.

1. What is RCS chat?  

RCS (Rich Communication Services) is a new standard for messaging that is intended to provide a better experience than SMS. With RCS chat supported features such as high-quality media, read receipts, typing indicators, suggested replies, interactive buttons, carousels and much more, it is recommended as a premier messaging channel for users.

RCS is designed to be available on the native messaging app on supported devices, so users get a rich, interactive messaging experience, without having to download a separate messaging app. Unlike SMS, which relies on the mobile carrier’s traditional messaging network, RCS uses internet connectivity and RCS infrastructure to deliver messages, enabling the richer features that SMS cannot support.

Since RCS is integrated into the device’s messaging app, users can also choose whether to enable RCS chats. In Google Messages, users can turn it on by going to Profile picture → Messages settings → RCS chats → Turn on RCS chats.  

To understand where RCS fits in the broader messaging landscape, it is useful to compare it with SMS, MMS and OTT messaging.

2. What is the difference between SMS, MMS, OTT and RCS?  

a) Definition  

SMS stands for Short Message Service. It is the standard technology used to send short text messages (up to 160 characters) between mobile phones over a cellular network rather than the internet.

MMS stands for Multimedia Messaging Service. It is a standard mobile phone technology used to send and receive rich media content - such as images, audio clips, GIFs and short videos - over a cellular network.

OTT (Over-the-Top) messaging is text and media communication sent via the internet. Popular examples include WhatsApp, Telegram, and Facebook Messenger, which bypass traditional telecom text fees.

RCS (Rich Communication Services) messaging is a modern communication protocol designed to replace traditional SMS and MMS text messages. It brings smartphone texting up to the standard of modern apps, offering high-resolution media sharing, typing indicators, read receipts and larger file sizes all through a phone's default messaging app.

b) Choices in message content and media support

SMS is limited to short plain-text characters - up to 160 characters only.  

MMS extends SMS to support multimedia content such as images, audio, GIFs and short videos. However, media is subject to carrier and file-size limitations and may be compressed.

OTT messaging supports a much wider range of content, including high-resolution images and videos, GIFs, stickers, files, voice messages and interactive elements.  

‍RCS combines the reach of traditional messaging with richer content, supporting high-resolution images and videos, GIFs, stickers, files, suggested replies, CTA buttons, carousels and rich cards directly within the native messaging app.

c) Seamless delivery and connectivity

SMS works over the mobile carrier’s cellular network, so it does not require mobile data or Wi-Fi. Its simplicity gives it broad reach, even on basic or older devices.

MMS also relies on the mobile carrier’s network, but multimedia messages can depend on carrier support and network. This can make delivery less seamless than standard SMS, particularly when sending larger media files.

OTT messaging uses an internet connection and requires both the sender and recipient to use the same messaging platform.  

RCS uses an internet connection to deliver messages through RCS infrastructure while working within the phone’s native messaging experience, but both the device and network must support RCS.  

d) Security

SMS has limited security because messages are not end-to-end encrypted, making SMS unsuitable for highly sensitive information.

MMS, similar to SMS, works without end-to-end encryption, so the content is not protected from intermediaries.

OTT messaging can offer stronger security because many platforms use end-to-end encryption, meaning only the sender and recipient can access the message content.  

Personal RCS messaging has encryption is on by default when you send messages to other Google Messages users who also have RCS enabled, protecting messages from being accessed by Google or other third parties. RCS Business Messaging uses encryption in transit and verified sender profiles, but it does not use end-to-end encryption.

3. What is the difference between RCS and RCS Business messaging?

RCS chat is a protocol that enhances the person-to-person (P2P) messaging experience by offering richer interactions you’d typically find in a separate messaging app (such as WhatsApp) directly within the native messaging app on your smartphone.

RCS Business Messaging is the application-to-person (A2P) of RCS for brands to communicate with their customers. This implies that businesses can send encrypted, interactive and media-rich campaigns or messages straight to a user's native mobile messaging program, without the need for third-party chat software.

4. How does RCS business messaging work ?  

RCS business messaging works through a combination of GSMA standards, RCS infrastructure, mobile carriers and messaging providers.  

• The GSMA defines the RCS standard through the Universal Profile, which sets the rules for how RCS should work across devices and networks.  

• Google provides a major part of the RCS infrastructure through Google Jibe and RCS for Business, while mobile network operators enable RCS for their subscribers.  

• For businesses, an RCS service provider provides the API and platform needed to create and send RCS Business Messages without the business having to connect directly to carrier infrastructure.

The journey looks like this:  

Business → RCS BSP/CPaaS → RCS infrastructure → Mobile carrier → Customer's phone.  

The business creates a message through the BSP's dashboard or API, the message is routed through the RCS ecosystem and the customer's carrier and it appears in the customer's native messaging app - such as Google Messages or Apple iMessages - if RCS is supported and enabled.  

A key requirement: RCS must be enabled on both the sender’s and recipient’s devices for the message to be delivered as an RCS message.

How to enable RCS messaging on Android?

To enable RCS messaging, Android users should do the following:

1. Navigate to Google Messages on your phone.

2. Tap your profile picture or icon and then open Message Settings.

3. Tap RCS chats.

4. Turn on RCS chats to enable RCS messaging.

How to enable RCS messaging on iPhone?

To enable RCS messaging, iPhone users should do the following:

1. Navigate to Settings on your iPhone.

2. Scroll down and select Apps at the bottom of the screen.

3. Select Messages from the available Apps.

4. Scroll down until you see the Text Messaging section, with RCS Messaging listed at the top of the category.

5. Click on RCS Messaging. On the next screen, if the toggle is green, RCS is enabled on your phone. If not, you can simply flip the toggle to turn on RCS Messaging on your phone.

5. What Are the Features of RCS (Rich Communication Services) messaging?

Instead of relying only on plain text, RCS messaging allows conversations to include multimedia, buttons, cards and other interactive features directly within the messaging experience.

a) Richer, More Engaging Messages

Unlike traditional SMS, RCS is not restricted to the 160-character limit, allowing businesses to send detailed messages without splitting them into multiple SMS segments.  

With rich media support, one of the biggest advantages of RCS, high-resolution images, videos, audio files, GIFs and documents such as PDFs can be send. RCS business chat also supports rich cards and carousels, which allow businesses to present products, services, offers and more in a structured format.  

Together businesses can communicate information through a richer mix of text and visual content, enhancing customer messaging experience.

b) Interactive Conversations

RCS turns messaging into a more interactive experience through suggested replies and customizable calls to action (CTAs). Instead of asking customers to type a response or leave the messaging app to complete an action, businesses can provide options such as Track Order, Book Appointment, Shop Now or Contact Us directly within the message.

Google Messages’ Magic Compose is an experimental feature with limited access. Powered by Google’s generative AI technology, it suggests personalised, stylised replies based on the context of your conversation. For businesses, this can help customers respond more quickly and effortlessly, potentially improving engagement. This feature is currently present only for P2P conversations but is likely to rolled out for A2P conversations in the future as well.

Google Messages now supports persistent suggestions alongside traditional transient suggestions for RCS business messaging. Businesses can send a single text containing both types simply by setting individual buttons to "persistent" mode.  

‍

The image above shows a real-life example of how these RCS Messaging suggestions works.

‍c) No external application required

Another important advantage of RCS chat is that it works through supported native messaging experiences, meaning customers do not necessarily need to download another application just to interact with a business. This removes an additional barrier between businesses and their customers.

d) Advanced Analytics

RCS Business Messaging provides businesses with messaging insights such as submitted, delivered, read, sent and undelivered. These insights help businesses measure campaign engagement, customer responses and message performance more effectively.

e) SMS Fallback:  

When RCS is unavailable because a device or carrier does not support it, messages can fall back to SMS, helping businesses maintain message reach instead of losing the communication entirely.

f) Cross-App Integrations

RCS business chat can connect messaging experiences with other services and applications, enabling use cases such as digital wallets, maps, payments, booking services and other third-party functionality directly from the customer conversation.

6. What are the benefits for a business using RCS business messaging?

‍a) Built for Business Communication

The features of RCS can make a business messages more trustworthy and useful.  

An RCS chat is more interactive than conventional SMS, combining the stability of SMS with the rich features of OTT chat apps, such as images, videos, location and route-map sharing and links, helping businesses create more useful customer experiences.

For customers, verified sender profiles can display a business’s name, logo and other identifying information, helping customers recognize who is contacting them. Sending messages from a verified business sender can build customer confidence and make conversations feel more secure and trustworthy.

For businesses, read receipts, typing indicators and two-way conversations provide greater visibility into customer engagement. Business senders can connect with customers without relying on separate apps, while RCS keeps the conversation within the customer’s native messaging inbox.

b) Better Conversion Rates:

Interactive features such as CTA buttons, suggested replies and product carousels let customers take action directly within the messaging experience. GreenAds Global with its trusted clients, have reported up to 3.5× higher conversion rates for RCS campaigns. This is not to say that it is a constant always - results vary by campaign ideas, audience and use case. With our help, you can create and increase customer conversion results.

c) Maintain Visibility in the Inbox:

Stay top of mind throughout the customer journey by keeping your brand easily accessible in the customer’s native messaging inbox. Businesses can use RCS for timely promotions, order updates, appointment reminders, support messages and other communications without relying entirely on email or separate apps. RCS Business Messaging can be used by businesses of all sizes to create branded, interactive conversations and maintain a consistent customer experience across the network.

7. RCS on iPhone and Android: What Businesses Need to Know

RCS messaging works across supported Android and iPhone devices, allowing businesses to deliver richer messaging experiences without requiring customers to download a separate messaging app.  

Apple introduced RCS support with iOS 18, enabling iPhone users to exchange RCS messages with supported Android users and networks. For businesses, this significantly expands the potential reach of RCS Business Messaging.

Here are the requirements :

• iOS Version: iOS 18.1 or newer

• Cellular Plan: A mobile network provider that supports RCS on iPhone

• Enabled Settings: RCS and business messaging toggles turned on

However, RCS availability is not universal. The customer's device, mobile carrier, region and RCS configuration can affect whether an RCS message is delivered as RCS. Businesses should therefore consider SMS fallback when designing an RCS messaging strategy.

8. Is RCS business messaging secure?  

When a business sends an RCS message such as: “Your order has shipped.”, the message travels through several systems:

Business → BSP/aggregator → RCS infrastructure → carrier → customer

The connections between these systems are protected with transport encryption (TLS). However, the message is not end-to-end encrypted because intermediaries in the delivery chain can access the message content.

This is important for businesses because RCS Business Messaging is designed for things like marketing campaigns, promotions, notifications and order updates, rather than situations where the message content must remain inaccessible to intermediaries.

9. What encompasses a good RCS marketing strategy?

1. Segment Your Audience and Personalize Every Message

RCS marketing becomes more effective when the same message is not sent to every customer. Segment your audience based on factors such as purchase history, location, interests or engagement level and then tailor the campaign message to each segment.

For example, a fashion brand could show a new collection to recent website visitors, send a personalized offer to previous buyers and use a different message to re-engage customers who have not purchased recently.

The goal is to make every campaign feel relevant to the recipient rather than simply promotional.  

2. Design campaigns around the customer journey

RCS messaging works particularly well when it is connected to different stages of the customer journey rather than being used only for promotional broadcasts.

The key factor in campaign design involves 4 key factors:  

Discover → Engage → Convert → Retain

• Discover: Send personalized offers, product announcements or rich promotional content.  

• Engage: Use carousels, suggested replies, and two-way conversations to answer questions.  

• Convert: Use clear CTAs to drive purchases, bookings, registrations or enquiries.  

• Retain: Send order updates, appointment reminders, loyalty offers and customer-support messages.  

This approach turns RCS chat from a simple messaging channel into an interactive customer communication channel.

3.Test, Measure and Optimize

RCS marketing should be treated as an ongoing optimization process. Track campaign performance to understand which messages, audiences, media formats and CTAs generate the strongest results.

You can also run A/B tests on message copy, images, offers, CTAs and audience segments. For example, test whether Shop Now or Explore Products generates more clicks.

The objective is not simply to measure how many messages were delivered. It is to identify which elements move customers from receiving a message to taking action.

10. RCS for Business: Industry-Wise Use Cases

Here are some of the most relevant use cases:

Healthcare : Healthcare providers can use RCS messaging service to send appointment confirmations, consultation reminders, lab-report PDSs and more. Rich cards and CTAs can also help patients book, reschedule or confirm appointments directly from the conversation or get to know new services that can be availed by them.

E-commerce and Retail : Retailers can use RCS to showcase products through rich cards and carousels, share personalised offers and send order confirmations, shipping updates and delivery notifications. Customers can also use interactive CTAs to shop, buy and track orders without leaving the messaging experience.

Banking and Financial Services : Banks and financial institutions can use RCS for transaction alerts, payment reminders, account updates, loan offers and card-related notifications. Suggested replies messages can also guide customers toward actions such as making a payment, contacting support.

Travel and Hospitality : Airlines, hotels and travel companies can use RCS to send booking confirmations, itinerary updates, check-in reminders, boarding information or seasonal offers. Carousels and CTAs can also help customers explore upgrades, add-on services or booking options.

‍Educational institutions can use RCS for admission updates, application notifications, class reminders, exam alerts and fee reminders. EdTech companies can also use rich media and interactive CTAs to promote courses and drive registrations.

Automotive : Automotive brands and dealerships can use RCS for test-drive bookings, service reminders, vehicle updates and promotional offers. Customers can receive vehicle information, explore models and use CTAs to schedule a dealership visit or service appointment.

Real Estate: Real estate businesses can use RCS to share property recommendations, project details, site-visit reminders and personalised offers. Rich cards and carousels are particularly useful for showcasing multiple properties within a single conversation.

Food and Restaurants : Restaurants and food-delivery businesses can use RCS for order confirmations, delivery updates, personalised promotions, menu recommendations and reservation reminders. Rich cards and CTAs can make it easier for customers to browse menus, place orders or book a table.

b) The GreenAds Global RCS API: Built for Smarter RCS campaigns

Businesses need to create the right message format, add engaging media, get templates approved, select the right audience, schedule campaigns and track what happens after delivery.  

The GreenAds Global RCS messaging platform brings these activities together in one place, making RCS campaign management easier to manage from creation to reporting.

Template creation:

The template creation process starts with choosing the right template category: Transactional or Promotional. Our dashboard automatically categorizes templates based on the content and purpose of your message. Businesses can create templates based on the type of communication they want to send, ensuring each message is aligned with its intended use.

Templates are then submitted for approval, with approval typically taking up to 24 hours.

Turn Approved Templates into Campaigns:  

For every campaign, two useful options are available: Send Test and Schedule Later. Businesses can first send a test message to a small audience of their choice to verify the content and experience before sending it to the full audience. They can also create campaigns in advance and schedule them for a later date.

With a Standard Campaign, businesses can select the campaign name, choose the template type, use an approved template and send it to customers anywhere in the world. What makes GreenAds Global user-friendly is how the contact numbers of customers can be copy pasted into our dashboard, instead of manually typing in potentially thousands of contacts or uploading excel sheets. For standard campaigns, contacts can be added by copying and pasting up to 15 lakh contacts at a time.

For campaigns where the content needs to be personalized for each customer, for example, the customer’s name, the Dynamic Campaign is the perfect option that supports up to 3 lakh contacts.  

Another advantage with GreenAds RCS messaging service is the SMS Fallback feature. When fallback is enabled, the campaign can automatically send an SMS version of the message to ensure that important communications still reach the customer. If you plan to use SMS fallback with your RCS campaign, it is important to prepare the SMS message template before launching the RCS campaign. Once the DLT-approved SMS template is approved, it can be configured as the fallback message for your RCS campaign, so customers can receive the SMS version when the RCS message cannot be delivered.

Multichannel Campaign

With GreenAds Global platform, RCS, SMS, and WhatsApp can all be managed from a single platform, eliminating the need to switch between multiple tools. Instead of sending every message through the same channel, segment your customer base and choose the channel that makes the most sense for each audience and use case.

Use RCS when rich, interactive content can drive greater engagement, while SMS or WhatsApp can handle messages where a simpler or more cost-effective format is sufficient. By matching each message to the right channel, you can bring down your overall messaging costs while still delivering the right experience to customers.

With the increase in RCS per-message pricing as of September 1^st ,2026, segmenting your customers, choosing the right messaging channel (WhatsApp, RCS or SMS) and message type (promotional or transactional) for each audience matters more than ever.

Keep Customer Conversations Within Reach:  

Campaign messaging is only one side of customer communication. When a customer responds, businesses also need a way to keep track of the conversation.

The GreenAds Global RCS messaging Inbox helps businesses monitor customer messages received through a linked Excel sheet, providing a simple way to maintain visibility over incoming responses and follow-up activity.

This becomes particularly useful when RCS campaigns are designed to generate responses rather than simply deliver information.  

Measure Campaign Performance:  

Businesses can see the number of messages submitted, delivered, read, sent and undelivered at a glance. This makes it easier to identify delivery issues, understand how many customers have received or viewed a campaign. The reporting view can also be filtered by date, allowing businesses to analyse specific campaigns or compare performance across different periods.

‍

While the RCS messaging rate has increased, the pricing structure now provides a clearer distinction between promotional and transactional RCS messaging, helping businesses better understand and plan their RCS messaging costs based on the type of traffic they send.

Tiered messaging pricing means RCS messages are priced according to their message category, rather than applying one rate to all traffic.
