Quick answer. By 2030, RCS is likely to be the default for business messaging in supported markets, with SMS relegated to a pure universal fallback. Expect near-universal rich-messaging reach across Android and iPhone, person-to-person end-to-end encryption as standard, AI agents handling most routine brand conversations, and conversational commerce, discovery to purchase in-thread, treated as normal. Newer capabilities finalized in Universal Profile 4.0, like in-conversation video and richer formatting, should be widely available, pushing the inbox closer to an all-purpose engagement surface. (This is a forward-looking projection, not a certainty.)
The honest caveat: timelines in messaging slip, and rollout of each new capability depends on carriers and device makers. But the direction is well-supported by current trajectory, rising adoption, Apple’s entry, E2EE, UP 4.0, and the AI/commerce convergence all point the same way.
For businesses, the implication is to build RCS competence now. Those running real RCS programs today will have a structural advantage as video, richer formatting, and AI agents become mainstream, rather than starting from zero when competitors are already at speed.
Key facts
- Projection: RCS as the default business channel by 2030, SMS as pure fallback; P2P E2EE standard; AI agents and conversational commerce normalized.
- Grounded in current trajectory (adoption to ~3.8B by end 2026, Apple support, UP 3.0 E2EE, UP 4.0 video/rich text), but rollout timing depends on carriers/devices.
- Forward-looking and uncertain, framed as a projection, not a guarantee.
