RCS (Rich Communication Services) is an upgraded messaging protocol that enables rich media content, branding, interactive buttons, read receipts, and typing indicators — all within the native messaging app. Unlike SMS which is limited to 160-character plain text, RCS delivers app-like experiences without requiring users to install any additional application.
Apple introduced RCS support in iOS 18 (2024). While RCS is now available on iPhones, the experience may vary compared to Android where Google Messages provides full RCS functionality. SMS remains the most reliable fallback for reaching iOS users who may not have RCS enabled.
Yes, RCS messages are typically priced higher than traditional SMS due to the rich media capabilities and enhanced delivery features. However, the significantly higher engagement rates (open rates above 90%, interactive CTAs) often deliver better ROI. Duotech Solutions offers competitive RCS pricing tailored to your campaign volume.
Yes, RCS can deliver OTPs with a richer verification experience including branded sender identity and auto-fill suggestions. However, SMS remains the universal fallback for OTP delivery since it works on every phone without internet. Many enterprises use a dual-channel approach: RCS as primary with SMS fallback.
Currently, RCS does not require DLT registration with TRAI in India, as it operates through Jio's RCS platform. However, Bulk SMS requires mandatory DLT registration for both promotional and transactional messages. Duotech Solutions can guide you through the DLT process for SMS and set up RCS campaigns simultaneously.
RCS penetration in India is growing rapidly, primarily driven by Android's Google Messages app. With Jio's partnership with Google, a large and increasing segment of Indian smartphone users can receive RCS messages. However, SMS still has universal reach. Duotech helps you plan campaigns that leverage RCS where available and gracefully fall back to SMS.
