What Is RCS? A 30-Second Explainer for Business Owners
If your phone can send a text, it can send an RCS message. RCS stands for Rich Communication Services. Think of it as texting 2.0: instead of plain words and a link, your messages can include high-resolution photos, tappable buttons ("Book Now," "See Menu," "Confirm"), swipeable carousels of products or services, and your business logo right at the top of the conversation.
Your customer does not download an app. They do not create an account. The message simply shows up in the same Messages app they already check dozens of times a day. For a local business owner, that means every promotion, appointment reminder, and follow-up you send can look and feel like a mini mobile app, delivered instantly, with zero friction.
If SMS is a sticky note on someone's door, RCS is a beautifully designed postcard with a QR code that lets them act on the spot.
What Changed: Apple, iOS 18, and the Tipping Point
For years, RCS was stuck in the Android world. Google pushed it across Android devices starting in 2019, but Apple would not adopt the standard. That meant any message sent between an iPhone and an Android device fell back to plain SMS: green bubbles, compressed images, no read receipts.
Everything changed in September 2024 when Apple shipped iOS 18 with native RCS support (Sinch, 2025). Overnight, the addressable market for RCS in the United States jumped from roughly 45-50% of smartphones (Android only) to over 90% of all smartphones (Google, 2025).
The global numbers are just as striking. As of early 2025, there are between 2.1 and 2.5 billion monthly active RCS users worldwide (Sinch, 2025). In the United States alone, Google reported more than 1 billion RCS messages sent per day as of May 2025 (Google, May 2025).
This is not a niche channel. It is not a future technology waiting for adoption. It is the default messaging experience on the vast majority of phones in your customers' pockets right now.
RCS Capabilities: What You Can Actually Send
Let us walk through every major RCS feature with a text-based mockup so you can see exactly what your customers would receive.
Rich Cards
A rich card bundles an image, a headline, body text, and up to four action buttons into a single visual unit. Think of it as a mini landing page that lives inside a text message.
The photo renders in high resolution directly in the message thread. "Reserve Now" can open your booking page or trigger an in-message reservation flow. "See Menu" links to your online menu. Compare that to an SMS that reads: "Tonight's special: salmon $28. Visit ourrestaurant.com/menu." No photo. No buttons. Just a URL most people will not tap.
Carousels
A carousel is a set of up to 10 rich cards arranged horizontally. Customers swipe left and right to browse, then tap a button on the card they like. It is the same interaction pattern as scrolling through Instagram stories or swiping through a dating app.
Each card has its own image, description, price, and call-to-action button. This is ideal for businesses that offer multiple services or products at different price points.
Suggested Replies (Pill Buttons)
Suggested replies are pre-written response options that appear as tappable pill-shaped buttons below a message. Instead of asking a customer to type a reply, you give them one-tap options.
When a customer taps "Loved it!", you can automatically send a follow-up asking for a Google review. When they tap "Not great," you route them to a private feedback form so you catch the problem before it becomes a 1-star public review. This turns a simple text into an intelligent routing engine.
Verified Sender Profiles
When you send an SMS, the customer sees a 10-digit phone number. Maybe they recognize it. Probably they do not. They might assume it is spam and delete it without reading.
RCS verified sender profiles replace that phone number with:
- Your business name displayed prominently
- Your logo shown as the conversation avatar
- A verification badge confirming your identity
- Your brand colors in message elements
The difference between a text from "1-555-382-9901" and a message from "Riverside Bistro" with a logo and a blue checkmark is enormous. Trust goes up. Open rates go up. Spam reports go down.
High-Resolution Media
SMS can technically include images via MMS, but they are compressed, often blurry, and limited to about 500KB. RCS supports images up to 100MB and video up to 100MB, rendered natively in the message thread at full resolution. Your food photography, before-and-after treatment photos, and salon portfolio shots actually look good.
Read Receipts and Typing Indicators
RCS includes read receipts and typing indicators by default. You know when a customer has seen your message. This data is valuable for optimizing send times and understanding which messages resonate. SMS offers zero visibility into whether a message was even opened.
RCS vs SMS: Head-to-Head Comparison
Here is how the two channels stack up across the metrics that matter for local businesses.
| Metric | SMS | RCS | Source |
|---|---|---|---|
| Open rate | ~98% | 90-95% | Gartner, 2024; Sinch, 2025 |
| Click-through rate (CTR) | 4-7% | 15-30% | Sinch, 2025 |
| Conversion rate | 3-5% | 20-40% | Infobip, 2025 |
| Cost per message | $0.01-0.02 | $0.01-0.03 | Juniper Research, 2025 |
| Media support | Text + links (MMS for images) | Images, video, carousels, buttons | GSMA |
| Verified sender | No | Yes (name + logo + badge) | |
| Read receipts | No | Yes | GSMA |
| Fallback | N/A | Auto-falls back to SMS | All RCS providers |
The headline number is click-through rate. RCS messages generate 3-7x higher CTR than SMS (Sinch, 2025). That is not a marginal improvement. That is a fundamentally different level of engagement. When your message includes a beautiful photo and a "Reserve Now" button, people tap it. When your message is a block of text with a URL, most people scroll past.
Conversion rates tell an even more dramatic story. RCS campaigns regularly achieve 20-40% conversion among those who engage, compared to 3-5% for SMS (Infobip, 2025). The interactive format, where the action is a single button tap rather than a multi-step website visit, removes friction at every stage.
RCS for Restaurants
Restaurants are among the biggest beneficiaries of RCS because food is inherently visual. A photo of tonight's special does more selling than any words ever could.
Dinner special rich card:
That "Reserve a Table" button links directly to your OpenTable, Resy, or website booking page. One tap from craving to confirmed.
Weekend brunch carousel:
Post-visit feedback with suggested replies:
"Amazing!" triggers a Google review request. "Could be better" routes to a private message with a manager. You capture feedback, protect your online reputation, and show customers you care, all in one tap.

RCS for Med Spas
Med spas sell multiple services across a wide price range, making carousels the ideal format for showcasing treatment options.
Treatment carousel:
Each card links to a specific treatment booking page. Customers browse, compare, and book without leaving their messaging app.
Appointment reminder with confirm/reschedule buttons:
One tap confirms. One tap opens available time slots. No phone calls, no reply codes, no friction. Interactive confirmations reduce no-show rates by 25-35% compared to plain-text reminders (Google RCS case studies, 2024).

RCS for Salons
A salon's biggest selling point is the work itself. SMS cannot show a stunning balayage. RCS can.
Stylist portfolio carousel:
Customers pick a stylist the way they pick a hairstyle on Pinterest: by looking at the results. Each card shows a signature look, a price, and a direct booking button for that specific stylist.
Rebooking prompt with suggested replies:
"Book Same Time" locks in the same day/time slot. "Browse Times" opens the scheduling page. "Not Yet" suppresses the reminder for two weeks. This kind of smart rebooking drives repeat visits without feeling pushy.

RCS for Fitness Studios
Fitness studios can replace wall-of-text class schedules with browsable, bookable carousels.
Class schedule carousel:
Showing available spots ("3 spots left") creates urgency. Each card has a class photo, schedule, real-time availability, and a one-tap booking button.
Challenge invitation rich card:
Challenges drive engagement and reduce churn. An RCS rich card with a compelling photo and a single "Join" button converts far better than a text-only pitch.
RCS for Coffee Shops
Coffee is visual. A photo of a beautifully crafted latte triggers a craving in a way that words never can.
Seasonal menu carousel:
"Order Ahead" links directly to your mobile ordering system. Customer sees the drink, craves the drink, orders the drink in under 10 seconds.
Loyalty update rich card:
Loyalty updates via RCS keep the program top of mind without requiring a separate app. The "Order Now" button closes the loop.
RCS for Dental Offices
Dental offices live and die by appointment attendance. Every no-show is lost revenue and a wasted time slot. RCS suggested replies make confirming effortless.
Appointment reminder with confirm/reschedule/cancel:
One tap confirms and updates your scheduling system automatically. "Reschedule" opens your online booking page with available times. "Cancel" opens the slot for another patient and triggers a rebooking sequence.
No phone calls. No "Reply C to confirm." No voicemails that never get returned. Dental practices using interactive RCS confirmations report 25-35% fewer no-shows compared to plain-text SMS reminders (Google, 2024).
The Verified Sender Advantage
Verified sender profiles deserve special attention because they solve one of the biggest problems in business messaging: trust.
A 2024 survey by RoboKiller found that 87% of Americans have received spam or scam text messages in the past year. As a result, consumers are increasingly skeptical of texts from unknown numbers. Your perfectly legitimate promotion competes with phishing attempts and fake delivery notifications.
RCS verified sender profiles break through that skepticism. When your business is verified through Google's RCS Business Messaging program, every message you send displays your business name, logo, and a verification badge. The customer knows who the message is from before they even read it.
The verification process typically takes 1-2 weeks and requires your business to meet Google's identity verification standards. Once approved, the brand identity is persistent across every message thread.
Cost Breakdown: More Per Message, Cheaper Per Conversion
RCS costs slightly more to send than SMS. Per message, RCS typically runs $0.01-0.03 compared to $0.01-0.02 for SMS (Juniper Research, 2025). That is a modest difference on a per-send basis.
But per-message cost is the wrong lens. The right metric is cost per conversion.
The Math
Suppose you send a promotional campaign to 1,000 customers.
SMS scenario:
- Cost: 1,000 x $0.015 = $15
- CTR: 5% = 50 clicks
- Conversion: 4% of clicks = 2 bookings
- Cost per conversion: $7.50
RCS scenario:
- Cost: 1,000 x $0.02 = $20
- CTR: 20% = 200 clicks
- Conversion: 30% of clicks = 60 bookings
- Cost per conversion: $0.33
You spent $5 more. You generated 58 more bookings. The cost per conversion dropped from $7.50 to $0.33, a 95% reduction.
Even with conservative estimates (say 12% CTR and 15% conversion for RCS), you still get 18 bookings at $1.11 each versus 2 bookings at $7.50 each. The math holds at every reasonable assumption.
Volume Pricing
Most RCS providers offer tiered pricing. At volumes above 10,000 messages per month, per-message costs for RCS can drop to $0.01-0.015, essentially matching SMS rates. For high-volume senders, the cost gap is negligible while the performance gap remains massive.

The Fallback Safety Net
One of the smartest design decisions in the RCS standard is automatic fallback. If a customer's phone does not support RCS (older device, unsupported carrier, or RCS disabled), your message automatically downgrades to SMS. The rich card becomes a text with the same offer and a link.
You do not maintain separate lists. You do not segment by device type. You send one message and the system delivers the best possible version to each phone. As of early 2026, roughly 90-95% of US recipients receive the full RCS experience. The remaining 5-10% get the SMS fallback (Google, 2025). That fallback percentage shrinks every month as devices update and carriers finish their rollouts.
This means there is zero delivery risk in adopting RCS. The absolute worst case is that a small fraction of your list gets the same plain-text experience they would have received with SMS anyway.
Frequently Asked Questions
Do my customers need to download anything to receive RCS messages?
No. RCS is built into the default messaging app on Android (Google Messages) and iPhone (Messages app, iOS 18+). Customers do not need to install an app, create an account, or change settings. If their phone supports RCS, they receive the rich experience automatically.
Can I send RCS messages from my existing SMS platform?
Many platforms that handle SMS now also support RCS, including Twilio, Sinch, Infobip, and Vonage. Check with your current provider. If they support RCS, you can typically upgrade without switching platforms.
Is RCS more expensive than SMS?
Per message, slightly. RCS runs about $0.01-0.03 per message versus $0.01-0.02 for SMS (Juniper Research, 2025). Per conversion, RCS is dramatically cheaper because it drives 3-7x higher click-through rates and 5-10x higher conversion rates. See the cost breakdown section above for the full math.
What happens if I send an RCS message to a phone that does not support it?
The message automatically falls back to SMS. The customer receives a text-only version with the same core offer and a link. You do not manage this manually. It is handled by the carrier and messaging platform.
How do I get my business verified for RCS?
You apply through your RCS messaging provider (e.g., Sinch, Twilio, Infobip). They submit your business for verification through Google's RCS Business Messaging program. The process typically takes 1-2 weeks and requires standard business identity documentation.
Will RCS replace SMS entirely?
Not immediately. SMS will continue to function as a delivery channel, especially for transactional messages and as the fallback for RCS. But for marketing, promotions, and interactive customer communication, RCS is rapidly becoming the better option. The trajectory is similar to how streaming did not kill television overnight but steadily absorbed viewership over a decade.
Getting Started
The shift from SMS to RCS is not a question of if but when. Apple's adoption of RCS in iOS 18 removed the last major barrier. Over 90% of US phones now support rich messaging, over 1 billion RCS messages are sent daily in the US alone (Google, May 2025), and the global user base has surpassed 2 billion monthly actives (Sinch, 2025).
For local businesses, the opportunity is straightforward: you can keep sending plain-text messages that look like every other text in your customer's inbox, or you can send beautifully branded, interactive messages with photos, buttons, and carousels that make it effortless to book, buy, or respond.
The businesses that adopt RCS early will benefit from novelty. Right now, most business texts are still plain. An RCS message with a rich card and a booking button stands out. That advantage will shrink as adoption increases, which is why moving sooner matters.
Regulr is building RCS rich cards and carousels directly into its automated retention flows. That means your re-engagement messages, win-back offers, and loyalty rewards arrive as branded, tappable experiences rather than plain text.
