What is RCS Messaging?

RCS is an upgraded messaging protocol, originally created to replace SMS and MMS as a native messaging platform. It offers many features that are also available on more modern platforms like WhatsApp, Facebook Messenger, and iMessage.

Similar to SMS, RCS messaging makes use of a phone’s native messaging app and relies on leveraging carrier networks or internet to deliver its messages. RCS messages are sent over Wi-Fi when it's available, or mobile data otherwise. This makes this channel particularly effective for businesses, as it allows customers to interact with branded content within their phone’s native messaging app instead of having to download a third-party application.

Does this mean that RCS has the same reach as SMS? Not yet. For a long time, RCS was only natively supported on Android operated devices. But Apple announced in 2024 that RCS support will finally come to iOS 18!

The Difference Between RCS, RCS Basic, SMS, and MMS

Short Message Service (SMS) has been the messaging standard for almost three decades, allowing short, 160-character messages to be exchanged between businesses and their customers. Despite the best efforts of WhatsApp, Facebook Messenger, iMessage, and many more, SMS is still one of the most popular messaging channels, serving billions of users around the world.

The biggest advantage SMS has over other messaging channels is probably it's availability. SMS is native on all mobile phones. However, what SMS has in ease-of-use, it lacks in features. Plain text, a character limit, and no fluff.

Multimedia Messaging Service (MMS) is built on the same technology as SMS with one goal in mind: allowing SMS users to send multimedia content similar to its competitors. Unlike SMS, MMS messages can include emojis, images and even short video and audio clips, as well as plain text with a higher character limit.

Rich Communication Services (RCS) is the newest contender for the new messaging standard, offering even more interactive features than MMS and elevating the messaging experience to the next level, rivaling the likes of WhatsApp, Facebook Messenger, iMessage, and more without a character limit.

RCS also offers a toned-down version of its services: RCS Basic Messaging. RCS Basic Messaging is similar to SMS, where no other media or features except text are included, and the character limit is 160. These RCS messages can be brand verified.

Will RCS will replace SMS and MMS? RCS will become the new universal standard that replaces SMS one day, but not today. Its current reach and availability are not yet able to rival SMS messaging.

RCS Messaging Coverage

RCS has full coverage parts of Europe (Germany, UK, Italy, France, and Spain), Canada, Mexico, Brazil, India, and the USA. In other countries, Google offers full or partial RCS support in cooperation with local mobile operators.

RCS is currently available for Android users, either through their native messaging app or Google Messages, and Apple has announced the release of RCS support on iOS 18. However, it will probably take a while for all mobile devices worldwide to become eligible for RCS messaging.

Until the reach and coverage of RCS messaging rivals that of SMS, the channels can perfectly co-exist and even complement each other. Send branded rich media content via RCS and ensure deliverability with SMS as a fallback.

The Features of RCS Messaging

The next-generation SMS protocol has a host of features and benefits that make it perfect for marketers looking to promote their brands to a market of millions.

Verified Sender

Brands using RCS have access to a variety of tools to show skeptical consumers the messages they’re sending can be trusted. The RCS messaging protocol requires that business users go through a verification process to eliminate fraud and spam. Customers can see that your business profile is verified, so they know that they are receiving legitimate messages. Once verified by one of the regulatory authorities, brands can display the following in their messages to reassure consumers:

• Brand information and verification

• Direct website link, email and phone numbers

• Company logo

• Verified sender profiles with a checkmark

Rich Media

RCS means you can send rich media such as images, video, carousels, and GIFs up to 105MB to your database of consumers, creating engaging messaging that encourages users to make the next step. General RCS messages also have no character limit, doing away with the 160-character limit of standard SMS messages.

Creating rich, interactive content can help to move consumers down the purchase funnel faster, reducing the number of clicks customers need to take to reach the compelling, benefit-driven content that drives conversions.

Suggested Responses and Actions

Making it easier for customers to interact with your brand, RCS features suggested responses and actions for your customers, seamlessly coaxing them through the customer journey. For example, you could set up a “schedule now” button to set up appointments and use RCS to confirm them with a “yes” or “reschedule” suggested response for customers. RCS has myriad options for customers to interact with brands by booking appointments, completing transactions, or even seeing real-time delivery updates without leaving their messaging app.

SMS Fallback

Not every mobile device out there will have RCS enabled. In those situations, rather than leaving messages undelivered, an SMS message will be sent as a replacement so your message will always get through.

Larger File Sizes

Larger file sizes enable your brand to share high-quality images and videos in messages up to 10MB. This means that your media files won’t be condensed, eliminating image or video degradation for your recipients.

RCS Messaging Use Cases and Benefits

RCS Marketing

Over 70% of consumers say RCS messaging would make them more likely to want to communicate with a brand. Using RCS for marketing, you can create rich, interactive content that showcases your brand and engages your audience right on their mobile phones.

RCS Sales

RCS brings many rich media features of popular messaging channels while offering benefits comparable to SMS. RCS messaging provides you with new ways to engage your audience and delivers your messages directly into the standard messaging channel of the phone of customers.

Marketing offers, booking appointments, browsing product catalogs, and even making purchases without leaving the native messaging app are well within its reach. A valuable asset to boost your sales!

RCS Security

The verified sender profiles of RCS Business are key to gaining customer trust and preventing fraud. Customers will see the business logo at the top of the message conversation, as well as the official company name with the verified checkmark, brand colors, and business details such as a website, email address and telephone number. Important cues for customers to know that the messages they are receiving are legit and that the sender can be trusted - and, equally important, that the absence of these visual cues means that they should be wary. Fraudsters impersonating a trusted business will now be recognizable by the absence of these features.

This makes the verifies sender profiles great for customer engagement, as customers will meaningfully engage more with content they can trust.
