RCS vs. SMS: Definitions, Differences & Current Trends

This article expands on the feature comparison between RCS and SMS, with revised information to reflect current advancements.

As businesses seek effective ways to communicate with consumers, the choice between SMS and RCS becomes crucial.

For now, SMS is the backbone of mobile messaging, offering a straightforward way to send concise messages. It’s highly effective across various industries, such as insurance, finance, and service sectors, though it has some limitations. For instance, SMS has a 160-character cap and lacks multimedia capabilities.

In contrast, RCS represents the next generation of messaging, providing features like read receipts, multimedia sharing, and interactive elements, all designed to create a richer user experience. With Apple set to make RCS available for iPhone users in late 2024, its adoption is expected to surge.

Whether you follow the traditional text messaging model or drive way off course… it all matters.

SMS vs. RCS message: Exploring SMS in Brand Marketing

First, this is the history of SMS messaging, which was introduced in the late 1990s, and from that moment on, it has revolutionized brand communication with consumers. This occurred due to simplicity and ease of use; subsequently, it became liked among the users due to the conveniences available.

➥ The first ever SMS was sent out in 1992, at the end of the 12th of December, and the message read “Merry Christmas.”

Thus, one may begin with something very ordinary and gradually evolve into the key medium in the market.

Let me explain how SMS works. SMS relies on the cellular network and isn’t supported online or through Wi-Fi. It operates using the GSM protocol.

The Short Message Peer-to-Peer protocol allows carriers to send SMS messages off the grid and hence doesn’t impact mobile data tariffs as these do not leverage the internet. On the other hand, radio-based techniques like RCS and messaging applications such as WhatsApp and Facebook Messenger require internet connections. They can send messages that are dependent on the users’ data plans.

Basic Functionalities of SMS
Text-Only Messaging	Character Limits and Delivery Notifications
SMS is a text-only service for sending short messages between devices. Its simplicity allows brands to send quick updates, promotions, and reminders directly to consumers.	SMS messages have a 160-character limit, promoting brevity. Delivery notifications inform senders when messages are successfully delivered, helping brands track engagement.
Limitations of SMS
Strict character limits that restrict complex messages.	Lack of rich media capabilities and advanced features like read receipts and interactivity.

For your brand to thrive, consider the challenges of SMS marketing and explore alternatives like RCS (Rich Communication Services).

RCS vs. SMS: RCS as the Future of Rich Communication

The biggest advantage of RCS is that it facilitates interaction with customers, making communication more engaging and friendly in comparison to SMS.

The platform, known as the new messaging, was created in 2007 as a development by the GSMA and is in charge of the mobile standards. However, Google later joined the process of RCS integration — it switched from integrating the service into SIM card management to a universal profile in which the service was bound.

The development was not free of trouble, especially because of disagreements between markets and their members, who refused to cooperate. In 2019, the Rich Communication Service standard was released.

Currently, message chatting has replaced traditional methods like calling for 86% of the respondents.

On top of that, RCS vs SMS for business makes interactions feel more dynamic and conversational for users. These are elements that transform messaging into a more human-like experience:

• High-resolution images
• Videos
• Carousels
• Real-time chat
• Typing indicators
• Reading receipts and much more.

One innovation that RCS brings to the table, which is crucial in the messaging landscape, is revolutionary and has several implications when comparing SMS vs. RCS messages.

Another advantage of the RCS business messaging API you might be looking for is mixing traditional SMS communication with multimedia content and interactivity. This increases the individualization and is most beneficial to the customer.

Enhanced Features of RCS Over SMS 

RCS does not mean just plain text; it is meant to deliver a rich and engaging experience that customers expect from quality services. Did you know that messages with rich media see up to a 300% increase in engagement rates compared to plain SMS?

Here’s how RCS marketing stands out:

Feature	Examples	Description
Multimedia support	Images, videos, audio	Unlike SMS, which only supports text and basic links, with RCS, businesses can share compelling, high-quality content.For instance, a real estate company can share high-quality property images or create video tours.
Group chats and interactive elements	Polls, clickable buttons, carousels	RCS makes it easier to create a community around your brand. Organize virtual events or surveys for more engagement.For instance, incorporating a “Vote for your favorite product” poll or a “Shop Now” button on the site can increase conversions by up to 40%.
User-friendly enhancements	Customizable interfaces	Studies show that 75% of consumers are more likely to remember a message if it reflects consistent branding.RCS makes messaging functional and immersive. Customizable interfaces allow businesses to maintain brand consistency by including the following:LogosColor schemesUnique design elements

SMS vs RCS Advantages and Key Differences

RCS vs SMS Text Functionality

When comparing the length and multimedia options of RCS vs. SMS text messages, the first is the winning solution. Rich media messaging boasts a more advanced messaging protocol compared to traditional SMS.

Here’s a breakdown of RCS and SMS features:

Message Length

 

SMS: The maximum character limit is 160 characters per message. If it exceeds this limit, multiple messages can lead to fragmented communication. But still, there are some advantages of SMS:

RCS: There is no strict character limit, allowing for longer messages. This flexibility means users can send messages that are more detailed and informative without worrying about cutting off important information.

RCS Chat vs. SMS: Multimedia Options

• SMS: Capable of basic multimedia messaging through MMS (Multimedia Messaging Service) to some extent, including images, videos, and audio, but usually at a higher cost with restrictions in file size, typically ~300KB.
• RCS: Try enhanced multimedia capabilities to provide rich communication features such as the ability to send higher res images, videos and other file types. RCS supports:
  • Instant digital files: High-resolution (hi-res) images and videos are easily shared.
  • Interactive buttons (Quick reply): Encourage recipients to respond with interactive prompts so they don’t need to construct a full text message. For example, a user can tap “Yes” or “No” for a question rather than actually type a response.
  • Location sharing: Users can share their real-time location or a static map directly within the chat, which allows improvement in the experience of organizing meetups or sharing directions.

SMS vs. RCS texting: Comparing User Experience

SMS:

•   Limited to plain text messaging.
•   It lacks interactive features like reading receipts, typing indicators, and multimedia support.
•   It feels outdated and less engaging, falling short of modern user expectations.

RCS:

• Significantly enhances engagement by introducing features like reading receipts, typing indicators, and multimedia support.
• Creates a more interactive, real-time experience similar to popular messaging apps like WhatsApp and Facebook Messenger.
• Brands report up to 74% higher customer satisfaction with RCS due to its more engaging and responsive nature (according to GSMA).

RCS vs. SMS Security Risks and Enhancements in Modern Messaging

SMS Security Risks

Notwithstanding the basics, SMS as a means of communication is vulnerable to some disadvantages that evolve with digital advancements. The old SMS protocol for personal messaging is still in use, and two-factor authentication (2FA) may not be as secure as it seems. 

SMS vs. RCS messaging: Key Vulnerabilities of SMS

SMS spoofing	It’s getting worse because the outdated protocols between mobile carriers allow phishing scams to balloon. Detecting spoofed messages becomes difficult in such scenarios.
SPS interception	SMS messages lack encryption, so codes, passwords, or payment details are vulnerable to hackers.
Outdated Two-Factor Authentication	Hackers do not sleep: they can gain access to accounts by hijacking phone numbers or intercepting one-time passwords (OTPs), which becomes a weak security method.
Account takeover	The worst scenario that may happen to Amazon accounts via linked phone numbers.

SMS vs. RCS message: RCS Security Enhancements

RCS business messaging is a revolutionary technology.

Users of iOS and Android are increasingly aware of the privacy risks with SMS. This fragility of SMS indicates just how acute the requirement for upgrading messaging systems really is.

Solutions like RCS, which offer end-to-end encryption, have found a very broad adoption base from mobile carriers and manufacturers.

The following discusses some ways RCS goes a step further in security:

1. End-to-end encryption: RCS messages are encrypted on the sender’s device and can only be decrypted by the intended recipient. Unlike SMS, that can be picked up in transit with no encryption.
2. Message integrity: Due to the cryptographic signature, RCS enables message integrity. Namely, the recipient can be sure that an interchange of a message is not tampered with in transit. SMS has no facility to ensure message integrity, which makes users susceptible to tampering.
3. Rich media functionality: RCS empowers rich media support, such as sending images, even videos and files. It assures security in terms of safe transmission. Whereas in SMS, huge media is not allowed; besides that, it lacks security.
4. User control over data: The user can control their chat settings, decide who can reach them, and view notifications. Should confirm this level of control is not available in SMS.
5. Authentication of the sender: This is crucial in preventing SMS spoofing, in which some unscrupulous individuals send forged messages pretending to be “real senders.” However, RCS ensures that users know whatever message comes from an authenticated source.
