RCS stopped being a pilot line item the moment Apple added support in iOS 18. iPhone exclusion had been the single largest barrier to adoption, and its removal turned a channel that reached part of a list into one that can reach effectively all of it. The active RCS user base is projected to reach 3.8 billion in 2026, and business messaging traffic on the channel grew 550 percent in 2024 after a 358 percent increase in 2023.

In the U.S., AT&T, Verizon, and T-Mobile all support it, alongside more than 55 networks worldwide.

None of that makes RCS a replacement for SMS, and hospitality marketers who plan it that way will spend more to reach the same guests. What it does is add three specific capabilities that SMS structurally cannot provide.

What RCS actually adds

Verified sender identity. An RCS business message carries the brand name, logo, and colours, with a verified sender profile behind it. SMS arrives from a short code or a ten-digit number that the recipient has to recognise or trust on faith.

Interaction inside the message. Buttons, carousels, and rich cards let the guest act without leaving the thread. SMS can only carry a link.

Richer media. Images and structured content render in the conversation rather than behind a click.

For hospitality, those map onto a small number of moments where the difference is real rather than cosmetic.

The four hospitality moments that justify it

Booking confirmation and pre-arrival. This is the strongest case. A verified, branded confirmation with the property image, the dates, and a button to modify or add is materially more reassuring than a text with a link — and the trust gap matters most precisely when money has just changed hands. It is also the message guests are most likely to reopen later, which is where the persistent rich card earns its place.

Check-in and on-property service. Buttons for late checkout, housekeeping, or a restaurant reservation convert an instruction into an action. The friction removed is small per message and compounds across a stay.

Restaurant reservation management. Confirm, modify, or cancel inside the thread. This is a genuine operational saving, because the alternative is a phone call to a host stand during service.

Promotional carousels for multi-property or multi-outlet brands. Showing three properties or three menus in one message is a thing SMS cannot do at all.

Everything else — a one-line reminder, an OTP, a “your table is ready” — is a message SMS delivers perfectly well, and RCS adds cost and complexity to no purpose.

The rule that keeps the budget honest

The prevailing guidance across the messaging platforms is consistent and worth adopting directly: SMS remains the right primary channel for most business messaging, and RCS is the right channel for specific high-value campaigns where the rich experience justifies the added complexity.

Operators getting the most from messaging in 2026 are running both, with explicit logic for which message goes where. The failure mode is migrating an entire SMS program to RCS on the strength of the growth statistics, then discovering that most of the program was transactional one-liners that gained nothing.

What to sort out before launching

Fallback behaviour. Not every recipient will receive RCS on every device and network. The fallback to SMS has to be configured, and the fallback copy has to make sense on its own — a message written around a button that arrives as plain text with no button is a broken message.

Sender verification. The verified profile is the main asset RCS provides, and obtaining it is an application process with the aggregator and carriers. Start it before building the campaign, not after.

Measurement that separates the two. RCS reports delivery and interaction differently from SMS. Reporting them in one blended column destroys the only evidence that would justify the additional spend. Track them separately from the first send.

Consent scope. Existing SMS consent language may not cleanly cover a richer channel. Have someone confirm the opt-in text supports what is being sent before migrating a list.

The honest position for 2026

RCS is no longer experimental — the platform reach, carrier support, and Apple’s participation settle that. But “essential” means essential to have in the mix for the moments that reward it, not essential everywhere. A hospitality program that moves confirmations, pre-arrival, and on-property service to RCS and leaves the rest on SMS is making the trade the evidence supports. One that moves everything is buying rich media for messages nobody was going to interact with.
