The creation of short message service (SMS) in the early 1990s marked a crucial moment in mobile communication. SMS was a revolutionary concept. It let users send concise text messages between mobile devices, which allowed people to stay connected at all times - something that had never been done before. Its simplicity and ease of use led to widespread adoption, and it’s still most people’s primary form of communication today.
Fast forward to the present day, and a new competitor has finally emerged on the messaging scene—Rich Communication Services (RCS). This next-generation messaging protocol builds upon SMS by offering a more feature-rich, interactive experience.
Below, we’ll explore the fundamental differences between SMS vs. RCS, along with their respective benefits and drawbacks. We’ll also discuss when each technology may be right for your business.
RCS vs SMS: What's the Difference?
Is RCS or SMS Better for Business Texting?
SMS is the oldest and most common form of text messaging. In fact, the first SMS message was sent in 1992—it read “Merry Christmas.” For the past two-plus decades, SMS has been the default text messaging method on mobile phones.
SMS allows users to send text-only messages of up to 160 characters via cellular networks. Since it’s universally supported by all mobile phones and doesn’t require Internet connection, it can help your business reach up to 7.3 billion people around the globe. It can also serve as a backup delivery method if other text messaging options fail.
While other text messaging methods are gaining traction, SMS remains popular for its simplicity, reliability, and affordability. Here are some key features of SMS:
Businesses that use SMS for internal or customer communication enjoy a variety of benefits, including:
SMS works on virtually all mobile devices across the globe. Unlike RCS, it doesn't require a smartphone, additional software or internet access. Regardless of your recipients’ mobile phone or cellular carrier, you can rely on SMS messages to reach your recipients, even in areas with poor data connectivity.
SMS is one of the most affordable messaging communication channels. Its text-only simplicity reduces design and development costs. And thanks to its wide reach and high engagement, SMS also boasts high ROI.
Since SMS is one of the most commonly used forms of communication, your recipients would already be comfortable interacting with it. In fact, SMS has probably the highest open rate that averages around 98%.
When used for marketing purposes, SMS is considered less intrusive than other channels, boasting higher engagement and conversion rates.
While SMS has a lot to offer, it also has some shortcomings. These include:
SMS’ plain text format limits its ability to engage customers, as there’s little room for custom branding, interactive content, or personalization, making it a less dynamic option than newer text messaging methods.
It is also constrained by its 160-character limit and as a result, it may have less impact than richer forms of text messages, like RCS.
SMS messages don’t feature end-to-end encryption, making them more susceptible to interception and unauthorized access. If your business manages sensitive information or operates in a highly regulated industry, this lack of security may present compliance concerns.
SMS doesn’t come with modern messaging features like read receipts, so you can’t confirm if the recipient has opened your message. There are no typing indicators, which means you won’t know if someone is responding in real time. Additionally, SMS only offers limited delivery notifications, and even these depend on the carrier and messaging platform.
Introduced in 2007, RCS is a next-generation communication protocol developed to replace SMS and MMS, offering advanced features similar to popular messaging apps like WhatsApp or iMessage, such as:
Unlike SMS, which rely on cellular networks, RCS operates over mobile data or Wi-Fi.
The adoption of RCS has been gradual. A major factor has been its lack of support on Apple devices until September 2024, despite Google's persistent advocacy for its adoption. Although Apple incorporated RCS following public pressure in 2024, it continues prioritizing iMessage as its most advanced messaging platform.
Overall, RCS is designed to provide a more engaging and dynamic platform for mobile communication and aims to set a new standard for the messaging world.
Here are some ways RCS messaging is poised to improve how businesses communicate with their contacts.
RCS provides users with a more dynamic and interactive messaging experience, going beyond the limitations of traditional SMS. Incorporating read receipts, typing indicators, and delivery notifications enhances user engagement.
With RCS, businesses can seamlessly share high-resolution multimedia content, such as images, videos, or even entire product catalogs, without compromising quality. The ability to convey information visually improves the message's appeal and effectiveness.
RCS offers unique branding capabilities that allow businesses to incorporate logos, visuals, and interactive elements within messages for a more professional and brand-consistent messaging experience. This reinforces brand identity, building customer trust and recognition through each interaction.
RCS excels in group chatting, offering businesses better features to create and moderate group discussions. This is ideal for team projects, customer support forums, or broadcasting information to broader audiences, fostering a collaborative and engaging environment.
Built-in rich cards, suggested replies, single-click buttons, and carousels transform RCS into an interactive powerhouse. Businesses can guide users through specific actions, simplifying processes like appointment confirmations or purchases.
RCS provides transparency by enabling users to see when their messages have been read. Real-time delivery notifications also give businesses updates on the status of sent messages, ensuring a reliable messaging experience.
The robust capabilities of RCS support different business communication needs, from marketing campaigns and transactional updates to customer support interactions. Its dynamic nature ensures comprehensive coverage for diverse scenarios.
RCS integrates modern security protocols to protect communication, addressing common vulnerabilities of SMS. This raises the bar for secure and trustworthy business messaging.
While RCS Messaging promises numerous advancements, it's not without its drawbacks. Here are a few to consider:
RCS adoption has been slow largely due to fragmented implementation across carriers and devices, which has limited its availability. For example, until Apple's recent adoption of RCS with iOS 18, the service was primarily limited to Android users, creating a divide that hindered cross-platform communication.
RCS relies on an active internet connection, such as Wi-Fi or mobile data, to send and receive messages. This means it may not work reliably in areas with poor or no connectivity, unlike SMS, which functions on basic cellular networks.
RCS messaging is generally more expensive for businesses than SMS. And while it’s still cost-effective, there may be variations in pricing models depending on carriers and regions. Moreover, using features like rich media, interactive buttons, or branded templates would require more resources for creative development.
To clarify the key differences between SMS vs. RCS, let’s quickly compare their core functionalities, security aspects, and user experiences.
