Rich Communication Services (RCS) expand on the functions that you would find in standard SMS or MMS, which is the most well-known multimedia texting system.

In this guide, we’re going to show you how rich communication services work and hit on some of its strengths and weaknesses. We will cover the following sections:

 

 

What is Rich Communications Services (RCS)?

Rich communication services (RCS) is a type of text-based protocol for mobile devices that was designed as a replacement for SMS and MMS messaging. RCS allow users to create group chats with friends, send images and videos, get read receipts, and have support for end-to-end encryption. Also, there’s no 160-character limit as with regular SMS.

Rich communication services first appeared in 2007 and was adopted by the Global System for Mobile Communications (GSMA) in 2008. It is available to Google Android users, and in December 2019, several U.S. carriers, including Verizon, AT&T, Sprint, and T-Mobile, committed to supporting the protocol.

RCS messaging works via mobile data or Wi-Fi, so if the recipient doesn’t have cell service but they are on a wireless network, you still have the ability to send them messages without a problem.

 

What Makes Rich Communications Services Unique?

Rich Communications Services (RCS) don’t use the same file formats as SMS or MMS. Besides the text transmission features, RCS messaging protocol allows users to send multiple data types such as pictures, videos, location data, pdf files, and even Microsoft Word documents. Customers can also complete transactions within the messaging app.

While it does have some security concerns, one feature that a business will find valuable is sender verification. With this feature, any texts a business sends will have to be verified first. That way, customers won’t have to worry about being spammed by third parties pretending to be their favorite brands. When a message is sent, the recipient will see the verified sender’s information – not just the phone number.

 

Business Benefits of Rich Communication Services

Rich communication services are convenient for the average user, but how does it provide new opportunities for your business?

 

More Interactive Messaging

One of the best benefits of rich communications services is the file size. Unlike SMS and MMS, RCS messaging has a file size limit that spans into megabytes, not kilobytes. This means that you will be able to send more multimedia content to your customers, such as audio and video.

Consider this: with traditional messaging, you can send a small .jpeg or .gif image to your customers, perhaps with a link, but is this enough to engage them? With RCS, your messages can have high-definition images, clickable buttons, and branding, which will create a more browser-like messaging experience. Rich communication services provide a much more detailed user experience, which results in better engagement.

 

One-App Functionality

Rich communication services also bring the ability to complete entire transactions right inside the messaging app. Instead of providing a link that opens in a mobile browser, RCS messaging handles all of the functionality on their own. Without the need to change software, this creates a universal profile for users.

While browsing through an app like Samsung Messages, the customer can select different color options for the product and click various sizes. Once they’ve selected the variation of the product that they want, rich communication services app allows them to complete the transaction by providing their payment and mailing details.

This is another way of increasing engagement by making things more convenient for customers. Instead of waiting for pages to load on their browser app, they can complete a transaction inside their rich communication services-enabled applications.

 

Easy Feature Integration

You’ll be able to integrate various features into your software easily. For example, chatbots are useful for helping customers navigate through menus. They also save money because there’s no need to involve your agents when self-service is enough. It’s easy to implement inside RCS software, and you can use a FAQ-style setup or incorporate AI to help your customers receive resolution.

Additionally, since this messaging easily sends location data, brands send information to the customer through the messaging app that will tell them how to reach their nearest brick and mortar location. This is also useful for those receiving deliveries since purchasing, shipping, and delivery confirmation are all possible with the messaging application.

 

Better Verification

With features like branding and sender verification, customers will know it’s your business that’s sending them communications/offers. That’s because once the sender is verified, branding will be consistent across the board. That’ll make for a better all-around customer experience.

Read receipts also help businesses better keep track of messages sent to customers. For example, you can use it for collection activities. When you send a message about a late payment, you will always know that the customer received and read it — that’s because RCS messaging offers rich analytics capabilities comparable to web analytics tools.

 

CPaaS Providers with RCS Messaging APIs

Communications platform as a service (CPaaS) providers help your developers add messaging APIs to your applications so you can extend your communications channels. This lets your customers reach your brand in ways that they find convenient. Remember, modern customers typically use more than three touchpoints to reach a brand. This means that you have to find the one with the best messaging features to meet your customers’ needs.

Here are some providers that include APIs for messaging. These will make reaching out to Android users on the mobile operators that support the system easier.

The Pros and Cons of Rich Communications Services

There are multiple benefits that make rich communication services great for business. Let’s take a look.

  • You can send higher-quality images and larger messages.
  • Location sharing is integrated into the messaging app as well as other group chat features that are useful when sending a message.
  • Video calling is supported by default.
  • You can send and receive documents with a customer that you’re already messaging.
  • You can use calendar integrations for scheduling meetings and invoice integrations for scheduling payments.
  • You can create a web-like experience for customers. Instead of just text, limited images, and links, you can brand your texts, add image carousels, and add clickable links to your messages.

RCS messaging is far from perfect. There are aspects that fall behind other types of messaging that may prevent a business from using it. Here are some weak points to consider when it comes to RCS messaging.

  • RCS messages do not have built-in end-to-end encryption.
  • RCS messaging only functions with a mobile phone number, so devices like tablets and standard Microsoft Windows and Apple desktop computers are not compatible.
  • The service is still relatively new, so it’s not available through all carriers at this point.
  • iPhone devices do not support this type of messaging with Android users. Non-iOS users can only send standard SMS messages to Apple devices.

Is RCS Messaging a Valid Successor to SMS?

RCS isn’t perfect – Apple’s iMessage has yet to really embrace the technology, which may be a major roadblock for some businesses that are looking to adopt. Also, RCS doesn’t currently provide end-to-end encryption. This type of encryption makes it very difficult for third parties to access messages, and without this encryption, VoIP security can be compromised. Fortunately, there were several hints that Google will soon be adding this feature.

This advanced messaging provides you with a key feature that helps you reach customers where they are most comfortable – in their favorite messaging app. Looking for additional ways to connect with your customer base?
