RCS vs SMS: Which One Should You Choose?

RCS vs SMS represents one of the biggest shifts in business messaging today. With 16 million SMS messages sent every minute worldwide and a staggering 98% open rate, SMS has dominated for over 30 years. However, RCS messaging is rapidly gaining ground, with a 358% global growth on Infobip’s platform in 2023 alone.
Understanding the Basics: What is RCS Messaging vs SMS
What is RCS messaging exactly? Unlike traditional SMS, RCS (Rich Communication Services) offers enhanced features like rich media sharing and interactive buttons. The difference becomes clear when we look at engagement metrics – 90% of rich media messages are opened within 15 minutes, increasing customer interaction by up to 45 seconds. While debates continue, the choice ultimately depends on your specific business needs.
What is SMS and how does it work?
Short Message Service (SMS) operates on cellular networks through standardized protocols that enable mobile devices to exchange text messages. Originally developed as part of the GSM standards, SMS transmits messages directly through cellular networks—not requiring internet connectivity. This fundamental aspect makes SMS universally accessible, even in areas with poor internet coverage.
Limitations of SMS for business use
Despite its widespread use, SMS presents several challenges for businesses:
- Character limit of 160 characters (70 with special characters or emojis) restricts complex communications
- Text-only format without rich media support limits visual branding opportunities
- Lacks formatting options like font styles or colors
- No read receipts or typing indicators to track engagement
- Delivery is not guaranteed, with studies showing 1-5% of messages get lost even during normal operations
The role of MMS in extending SMS capabilities
Multimedia Messaging Service (MMS) emerged as an extension of SMS, addressing several of its limitations. MMS allows businesses to send:
- Images, videos, and audio clips
- Longer text messages beyond the 160-character limit
- Slideshow presentations of multiple images
What is RCS messaging ?
An RCS message operates as a communication protocol that transforms ordinary text messaging into a feature-rich interactive experience. Essentially, it brings smartphone messaging closer to what users enjoy in popular messaging apps—but directly within your phone’s native messaging app, no third-party downloads required.
Unlike SMS, RCS operates over IP networks (mobile data or Wi-Fi), enabling advanced features similar to messaging apps. It supports rich media sharing, typing indicators, read receipts, and interactive elements directly within native messaging apps.
Key features like read receipts and media sharing
The difference between RCS vs SMS becomes immediately apparent when examining their capabilities. RCS messages offer:
- Enhanced media sharing – Support for high-resolution photos, videos up to 100MB, and GIFs
- Interactive elements – Typing indicators, read receipts, and group chat management
- Branding opportunities – Verified sender profiles and custom logos for businesses
- Extended character limits – Up to 250,000 characters per message versus SMS’s 160
- Security improvements – End-to-end encryption between Google Messages users
- Security improvements – End-to-end encryption between Google Messages users
Key Differences Between RCS and SMS
RCS and SMS operate on fundamentally different technological foundations. SMS uses traditional cellular networks, transmitting messages through dedicated channels within the mobile network infrastructure. In contrast, RCS relies on IP-based technology, similar to internet messaging apps, requiring either mobile data or Wi-Fi connectivity.
Technical Infrastructure Differences:
Message Capabilities:
SMS Limitations:
- 160 character limit per message
- Basic text-only format
- Limited MMS support for basic media
