Frequently Asked Questions

What is RCS messaging?

RCS (Rich Communication Services) is the next generation of SMS that transforms traditional text messages into interactive, media-rich conversations. With RCS, businesses can send branded messages with images, videos, carousels, action buttons, and even real-time chat directly through the user’s default messaging app, without needing an external app.

No, not all mobile phones support RCS. RCS works on most modern Android devices with Google Messages and carrier support. However, iPhones and some older Android phones do not support RCS natively. To ensure full reach, RCS platforms like TrustSignal automatically fall back to standard SMS when RCS isn’t available.

SMS is limited to plain text (160 characters) and lacks branding or interactivity. On the other hand, RCS is a modern upgrade that supports rich media (images, videos), branded sender IDs, action buttons, read receipts, and chatbot-like experiences—all within the native messaging app. It’s like turning basic text into a mini app experience.

Yes, RCS is a significant upgrade over SMS. While SMS is limited to plain text and basic delivery, RCS offers rich media, branded messaging, interactive buttons, read receipts, and two-way conversational flows—all in the user’s default messaging app. It delivers higher engagement, better UX, and improved business conversion rates.

RCS supports a wide range of rich media formats, including high-resolution images, GIFs, videos, audio files, PDFs, product carousels, location sharing, and even calendar invites. This makes RCS ideal for interactive campaigns, product showcases, ticketing, and more—all delivered inside the default messaging app.
