Bandwidth’s 2026 State of Messaging Report calls this the “biggest messaging transformation in a decade.” I’ve been on both sides of the RCS ecosystem — DevRel at Google building the Business Messages program, a stint as CTO at a GenAI startup, and now back at Google focused on RCS — and I think they’re underselling it. A decade? Try generational.

Here’s why, and where the real opportunity sits.

The RCS Gap #

One number matters more than all the others: 96% device coverage. Apple shipped RCS support in iOS 18; Android had it for years. That single move from Apple closed the last meaningful gap. Projections put active RCS users at 3.8 billion by end of 2026.

The uncomfortable companion number: 59% of enterprises are still “planning” their RCS adoption. Not piloting. Not testing. Planning.

That’s a 37-point spread between device readiness and enterprise deployment. I’ve started calling it the RCS Gap (catchy, I know), and it represents the biggest first-mover opportunity in business communications since mobile push notifications.

From the consumer’s perspective, their phone already supports rich, branded, interactive messaging. Carousels, quick-reply buttons, verified sender profiles with company logos. But what do they actually get from most businesses? Plain SMS. No branding. No interactivity. A six-digit code or a text blob with a shortened URL that looks indistinguishable from spam.

The enterprises that close this gap first won’t just see better engagement metrics (though they will; I’ll get to the numbers). They get something harder to measure: they look like they belong in 2026. Everyone else looks like they’re still sending faxes.

Why SMS Isn’t Going Anywhere (Yet) #

I need to be upfront about something, even though it’s not the narrative my team at Google would probably lead with: SMS remains indispensable for high-volume, cost-efficient reach.

RCS delivers richer interactions and measurably better results. But SMS reaches every phone ever made. Every carrier. Every country. The infrastructure matured decades ago, the cost structure makes sense, and deliverability — despite its recent problems — stays the highest of any messaging channel.

Smart brands aren’t choosing between SMS and RCS. They’re orchestrating across both, increasingly layering AI-powered conversational flows on top. The 10DLC registrations, toll-free numbers, and short codes that enterprises invested in don’t become worthless when RCS arrives. They become the fallback layer guaranteeing reach while RCS handles the rich, branded interactions.

Think of it less as replacing the road and more like adding a lane to the highway. (Not the most original metaphor, but it’s accurate.)

Trust as the Differentiator #

Something shifted in 2025, and I don’t think the industry has fully absorbed it: trust became the primary differentiator in business messaging.

Consumer trust in SMS keeps eroding. Spam, smishing, spoofed sender IDs — users have learned to distrust unknown text messages, and honestly, good for them. When a message from a short code claims to be from your bank, the rational response is suspicion.

RCS verified sender branding tackles this head-on. A verified RCS message shows the company’s name, logo, brand colors, and a verification badge. Visually distinct from everything else in the inbox. Confirmable at a glance.

This matters more than rich media carousels or interactive buttons. Trust sits underneath all of it. Without trust, no amount of interactivity converts. With it, even a plain text message performs better because the user believes it’s legitimate.

The campaign data backs this up. RCS messages with verified branding show 73-92% read rates. Click-through rates hit up to 7%, compared to SMS averages around 2%. Conversion lift over traditional channels runs about 20%. Not projections — reported metrics from live deployments across financial services, retail, and travel.

Deliverability: The Unsexy Metric That Wins #

When I talk to enterprise messaging teams about their decision criteria, the answer that surfaces most often isn’t “features” or “cost.” It’s deliverability.

Can you guarantee the message arrives? On time? To the right device? Content intact?

Sounds basic. It’s not. SMS deliverability has degraded significantly as carriers tightened filtering to fight spam. Legitimate senders get caught in carrier-side spam filters. Short code provisioning takes weeks. 10DLC registration requirements vary by carrier. The result: enterprise SMS deliverability — the percentage of messages actually reaching the intended recipient — has become unpredictable.

RCS improves this because verified sender registration separates legitimate business messages from spam by design. Carriers have strong incentives to deliver verified RCS messages (they can monetize the channel) and equally strong incentives to filter unverified SMS (spam degrades user experience). The economic alignment works in the enterprise’s favor for once.

Deliverability won’t make it into anyone’s keynote. But it determines whether your authentication flow works, whether your delivery notification arrives, whether your promotional offer actually reaches the customer. The boring stuff that keeps the lights on.

The Commerce Angle #

US social commerce projections hit $100 billion for 2026. The global conversational commerce market sat at roughly $11 billion in 2025, expected to double by 2030.

Those numbers matter because they signal where transactions are migrating. Consumers want to browse, ask questions, and buy within a conversation. Not on a website. Not in a separate app. In the messaging thread they already have open.

RCS fits this pattern natively: product carousels for browsing, quick-reply buttons for selection, payment integration for checkout, delivery receipts for confirmation. The whole purchase journey happens without leaving the messaging app.

Compare that to SMS-based commerce. Receive a text with a link, tap the link, load a mobile web page, browse the catalog, add to cart, enter payment info, confirm. Every step bleeds users. Every redirect adds friction.

The gap between those two experiences maps directly to conversion rates. I keep waiting for someone to prove me wrong on this one; nobody has yet.

AI Changes the Conversation (Literally) #

The other major shift heading into 2026: AI-powered conversational agents hitting messaging channels for real. Not chatbots-circa-2018 with decision trees and keyword matching. LLM-backed agents that understand context, hold conversation state, and handle multi-turn interactions without falling apart.

On an RCS channel, an AI agent can display product images, process returns, troubleshoot technical issues, schedule appointments, and escalate to a human when it hits its limits. The rich message format means AI responses aren’t limited to plain text; they include structured data, interactive elements, and media.

For enterprises, this reshapes what the messaging channel actually is. Not a secondary support channel. Not a notification pipe. The primary interface between business and customer.

That’s a strategic shift, not a tactical one. It rewrites org structures. It rewrites technology stacks. It rewrites how you measure success. (I realize that sounds grandiose. I’ve been saying it for months and haven’t found a more measured way to put it.)

The Orchestration Challenge #

The practical problem for enterprises entering 2026: orchestration. SMS for reach. RCS for rich, trusted interactions. AI agents for conversational intelligence. WhatsApp and other OTT platforms for specific markets. Voice for complex or sensitive stuff.

How do you decide which channel to use for which message, for which customer, at which moment?

This is where messaging platforms like Twilio, Sinch, and Infobip earn their margin. Channel orchestration — routing messages through the optimal channel based on device capability, cost, urgency, and customer preference — represents the intelligence layer sitting above any individual protocol.

The enterprises that figure this out gain a compounding advantage. Every message delivered on the right channel reinforces trust; every interaction handled by an AI agent on a rich channel reduces support costs; every transaction completed within a conversation eliminates web funnel friction.

Where We Stand #

The messaging landscape in 2026 has a weird paradox at its center: the technology works, but most enterprises don’t. RCS coverage sits at near-universal. AI agents handle production workloads. The commerce patterns have been validated. The trust mechanisms exist and function.

The gap isn’t technical. It’s organizational. The enterprise messaging team still evaluating vendors. The compliance department that hasn’t approved RCS sender verification. The product team that hasn’t designed conversational customer journeys. (If you’ve worked at a large enterprise, none of this surprises you.)

For those who close the gap, the rewards show up fast. RCS campaign data tells a clear story: higher read rates, higher engagement, higher conversion. AI agent economics point the same direction: lower cost per interaction, higher resolution rates, around-the-clock availability.

Business communication is moving toward conversation not because someone decided it’s trendy. Conversations are how humans prefer to interact — they always have been. The technology finally supports that preference at scale. The only question left: how quickly do enterprises stop planning and start shipping?
