SMS and RCS: Complementary solutions

Picture this: A customer is eagerly awaiting updates from your business. A simple SMS lands in their inbox—a quick, reliable message. But what if it could do more? Imagine adding rich media, clickable buttons, or your logo to that same message. That's where RCS steps in to enhance what SMS started.

SMS and RCS aren't rivals. They're allies. By combining the reach and simplicity of SMS with the interactive, branded experience of RCS, businesses can create messaging strategies that truly stand out.

Why SMS still matters

SMS is the foundation of business messaging. With its universal compatibility, it ensures your message reaches virtually any phone with no internet required. It's simple, effective, and unmatched for reliability. Whether you're sending appointment reminders, account updates, or time-sensitive alerts, SMS is the trusted channel that gets the job done.

But SMS isn't just about reliability. It's also about strategy. It provides:

• Failover functionality: If RCS isn't supported, SMS ensures your message still gets delivered.
• Scalability for global reach: Every device with a phone number supports SMS, making it the ultimate channel for reaching customers anywhere.
• Clear communication: Its concise format ensures messages are easy to read and act upon.

When you need a messaging solution that works everywhere, SMS is the backbone of your strategy. For businesses in sectors like retail and e-commerce or healthcare, this universal reach is essential for maintaining customer relationships.

How RCS takes messaging to the next level

Now, imagine those same messages with a boost of interactivity and branding. RCS allows you to:

• Enhance customer engagement: Add rich media like images, videos, carousels, and interactive buttons. Customers can take action, whether it's booking an appointment or completing a purchase, without leaving the message.
• Build trust with verified branding: Use your business logo, name, and custom colors to reinforce your brand identity and ensure customers know they're interacting with you.
• Leverage AI-driven personalization: Tailor messages to individual customers based on their preferences, location, or behavior to create more meaningful interactions.
• Track real-time insights: Gain access to delivery and read receipts, giving you the data you need to optimize messaging campaigns and improve engagement.

RCS takes messaging from basic communication to immersive customer engagement, creating a standout experience. Learn more about what RCS messaging is and its advantages for modern business communication.

The RCS adoption landscape

"RCS offers rich, interactive messaging experiences, and will allow businesses to engage with their customers in dynamic new ways. With Apple rolling out both RCS and RCS for Business support in select markets, we're seeing exponential growth in adoption. By summer 2025, Apple's support alone could translate to over one billion additional RCS users."

— Robert Gerstmann, Chief Evangelist and Co-Founder, Sinch

The RCS ecosystem has reached a critical inflection point. According to industry research, Apple's iOS 18 support contributed to a fivefold increase in global RCS traffic in 2024, with North America seeing a 14x surge. The rich communication services market reached $2.87 billion in 2025 and is projected to grow to $8.89 billion by 2030—a 25.37% compound annual growth rate.

Financial services leads adoption at 49%, followed by technology (39%) and healthcare (36%). For deeper insights into how RCS compares with traditional SMS, read our analysis on SMS vs. RCS messaging technologies.

SMS and RCS working together

The real magic happens when SMS and RCS work as a team. By combining SMS's reliability with RCS's enhanced functionality, businesses can create seamless messaging workflows that cater to every customer.

• Failover to SMS: When a customer's device doesn't support RCS, the message is automatically sent as SMS, ensuring deliverability.
• Layered engagement: Use SMS for quick updates or reminders and RCS for detailed, interactive communication.
• End-to-end customer journeys: Start with SMS to establish contact, then transition to RCS for complex interactions like bookings or payments.

This dual-channel approach ensures businesses can reliably reach every customer while offering enhanced experiences where possible. Check out RCS use cases for businesses to explore practical applications across industries.
