While billions of people send texts each year, there are other messaging channels that offer a lot more, like Rich Communication Services (RCS). But what is RCS messaging and how does it work?
RCS was built as a replacement for SMS. It allows Apple and Android users to enjoy many of the same features as other rich messaging channels like Apple iMessage or WhatsApp. While RCS was first conceived over 16 years ago, its adoption has surged recently, with over one billion monthly active users and global coverage from mobile operators. Now, with RCS message support expanding to Apple devices in some markets, cross-platform messaging is becoming even more seamless.
How is this good for your business? Let’s walk through how you can use RCS for better engagement and sales, and gain customer trust.
RCS is a messaging protocol for Android and Apple users that offers rich chat features like video, images, and other interactive elements. An RCS message allows users to send and receive high-quality media, create group chats, see typing indicators, and see read receipts.
In RCS chats, live chats can include multimedia like web pages, maps, and other images. These chats can take place directly in a user’s native mobile inbox (like Android Messages).
More people than ever are using SMS, and the biggest advantage it has over other messaging services is that it’s available on any mobile phone. However, it does have its limitations (the first text was sent in 1992!). That’s why, in 2006, the GSM Association (GSMA) set out to create the next step or evolution of SMS — RCS.
RCS was designed to upgrade SMS for modern systems and needs. That means more options, images, videos, and better security.
Sinch’s Robert Gerstmann said that one of the potential powers of RCS is that it can replace apps altogether. While that may sound radical, it is possible. Many of the most common uses of apps (checking balances, placing orders) could be handled with rich messaging. Plus, the security required for a company to get verified builds consumer trust, making them more likely to engage on that channel.
RCS chat is a communication protocol provided by Google for Android devices that empowers users with advanced communication features and capabilities like read receipts, typing indicators, high-quality media sharing, and more. This makes it a versatile, secure option for modern messaging.
After some lucky iOS 18 beta users got an early taste of RCS through carriers like AT&T, T-Mobile, and Verizon, Apple rolled out RCS chat in iOS 18 for person-to-person (P2P) messaging in some markets in September 2024. This means that RCS messaging is supported on both Android and Apple devices. If you have iOS 18 and your mobile carrier supports it, you can turn on RCS in your iPhone’s Message Settings.
While Apple was initially hesitant to adopt RCS, an Apple spokesperson in 2023 said that RCS offers better interoperability for cross-platform messages.
“We will be adding support for RCS Universal Profile, the standard as currently published by the GSM Association. We believe RCS Universal Profile will offer a better interoperability experience when compared to SMS or MMS. This will work alongside iMessage, which will continue to be the best and most secure messaging experience for Apple users.” -Apple spokesperson, 9to5Mac, November 16, 2023
Sinch’s Robert Gerstmann shared how quickly RCS chats could be adopted by iPhone users now that RCS is available in iOS 18.
“For previous versions of iOS, we have seen over 50% of all iPhones having the newest iOS version by winter, with that number increasing to 80% by the subsequent summer. If the adoption speed of iOS 18 matches that of previous iOS versions, this would translate to over one billion additional RCS users by summer 2025 thanks to Apple coming onboard.” – Robert Gerstmann, Chief Evangelist and Co-Founder at Sinch
While Apple has been light on the details about when we can expect RCS business messaging (RBM) on iOS, their support for RCS for P2P messaging (and the Universal Profile) is the first step towards that reality. We expect to learn more about Apple adopting RCS for business messaging later in the year.
RCS has full coverage in Canada, Mexico, Brazil, UK, Germany, France, Spain, Italy, and India. Other countries offer full support via Google’s RCS services or partial support, with a selection of local mobile operators providing RCS.
Android has more than 70% of the global market share, which means engaging Android users with the best, most interactive messaging available is a smart move.
To understand the differences between an RCS message and text messaging, it might be helpful to first understand the differences between MMS and SMS.
The primary difference is that, while MMS messages allow for multimedia attachments, RCS offers a much more interactive experience. RCS messages work with other elements of a smartphone, like a web browser, maps, and other apps, to offer the engaging experiences that consumers are yearning for.
So, does that mean that RCS will actually replace SMS? Probably not. RCS was created to replace SMS as a messaging protocol, but RCS messages require a mobile data connection. That’s why RCS can offer features similar to other OTT messaging platforms like Facebook Messenger, WhatsApp, and others. But unlike OTT apps, RCS doesn’t require users to download an extra app or create a new account. RCS works within the native messaging app that’s built into different devices.
SMS messages are still sent over a mobile network, meaning it can and should be used as a fallback when there’s no Wi-Fi or you don’t have a data plan (this is exactly what the Google Messages app already does between RCS and SMS, and what iMessage does when texting an Android device without RCS support).
Here’s a quick chart for you to reference that compares SMS/MMS and RCS for a few common factors.
SMS/MMS | RCS | |
---|---|---|
Network | Uses cellular network infrastructure. | Uses mobile data or wifi. |
Content | Limited to text (160 characters/SMS msg) and basic media (MMS). | Supports high-quality media, files, emojis, and rich content like images, videos, GIFs, and more. |
Features | Basic; no typing indicators or read receipts. | Includes typing indicators, read receipts, group chats, and more. |
Complexity | Universally supported, but lacks advanced features. | More complex due to carrier and device compatibility, but offers a modern, feature-rich experience. |
What does RCS do better than SMS texting? Well, just about everything!
RCS lets you build more engaging content and provide a better CX for those with RCS-enabled devices. Time and time again, RCS has been proven to lead to higher cart values, more conversions, and higher engagement than any other type of mobile messaging.
What does RCS mean for users? A better customer experience, more options, and increased security when messaging.
Here are a few more benefits of RCS to user experience:
To be able to send RCS messages, businesses must be verified. This process reduces spam and increases trust in verified senders. Recently, Google announced that RCS Business Messaging will replace Verified SMS in another step towards making RCS the new standard.
For your customers, when they know that you’ve been verified, they can trust the messages that they get from you.
Interactive and personalized features (as well as multimedia messaging assets) mean better engagement. Instead of sending a link to a product on your site or directing a customer to your online booking portal, you can do it right in the message.
When you make things as easy and fast as checking your texts, people will take advantage of what you offer them. For example, you can send RCS messages that contain elements like buttons with suggested actions. This saves time and helps direct customers towards actions that will solve their problems.
It’s also possible to send carousels of images, each of which have their own unique CTAs. If you’re helping a customer find a product they want or assisting them with booking an appointment, this is a huge time saver that they’ll appreciate.
Thanks to built-in analytics, you’ll be able to see who’s reading your messages and who isn’t. Handset delivery receipts, open rates, and read rates give you more in-depth information about the status of messages. Knowing when, where, and if your messages are being delivered will help you keep tabs on the performance of your messages.
Another benefit of better reporting is more data to use — which means better campaigns. Using the data from multiple campaigns, you can analyze them to see which parts of the message customers reacted to. Having these data points allows for better, more focused A/B testing opportunities.
Personalizing your messages for individual users isn’t just a dream anymore. By using chat histories, analytics, and other data, you can design better customer profiles. With better profiles, crafting compelling messages for automated responses or designing better marketing materials suddenly gets much easier.
What happens if someone doesn’t have strong enough service or connection to WiFi when you send them an RCS message? The messages will then be delivered through a fallback protocol or another app, including SMS, MMS, or WhatsApp. In short, your messages will always get to your customers, one way or another.
Like most other kinds of marketing and support, the ability to grow your business using RCS is only limited by your imagination and your budget. It’s good to remember just how powerful these messages can be — do you know any other form of outreach that’s as big a part of your customers’ daily routine as their text inbox? Neither do we.
Provide up-to-the-minute information on sales and promotions tailored to a customer’s tastes. With the added functionality of RCS, you can send them to your website, or give them directions to your location. You can even have them choose what they want and order it right from your message!
Here’s a real-life example: Macif, an insurance company with over 5 million policy holders in France, used RCS to have two-way conversations.
Macif’s campaign re-engaged contacts and increased campaign click-through-rate by 100%!
RCS allows your customers to engage with a conversational service (including live support or AI chatbots), for instance, to schedule or change appointments. You can also provide directions, sports scores, and shipping updates as they happen.
One of the most powerful ways to use RCS is to send account alerts. While many of these alerts have been limited to SMS or apps in the past, now you can send fraud alerts, payment posting messages, and service reminders right to your customers’ message inbox, with links and options for how to proceed.
Personalization is one of the most important parts of any communication or marketing strategy. Rich messages built around unique customer profiles lead to better engagement and sales. Create a profile for your customers based on past purchases and behavior to provide relevant, helpful recommendations.
Here’s another real-world RCS messaging example at work: Picard used an RCS campaign to lift sales and win customer loyalty. They created a conversational RCS experience that helped their customers imagine their holiday menus, taking into account dietary preferences, budget considerations, and even their desire to cook.
Watch the video to learn how Picard used RCS to personalize their customers’ shopping experiences.
Their campaign achieved great results, with a 42% increase in customer engagement and 10% more clicks to the website than Rich SMS.
A good RCS strategy is similar to SMS, push notification, and other mobile strategies. But it’s also different because it combines a lot of the features found in other channels into one.
Don’t send RCS messages without a specific purpose. Whether you’re giving access to a sale or sending an account alert, you need to make every message actionable. Luckily, the advanced features of RCS lets you create powerful CTAs. Segmenting messages by type is a good place to start:
If it isn’t broken, don’t fix it. But there’s nothing that says you can’t (or shouldn’t) make your relevant, useful messages look and work better. That’s a good way to think of an RCS campaign — a souped-up version of an SMS or email campaign that takes full advantage of new, rich features.
Combine CRM data, chat and order histories, and the results of customer surveys to build profiles that paint a fuller picture of who your customers are. From there, your team can devise and implement marketing and support strategies.
