Short answer: no. RCS is layering on top of SMS, not displacing it. The organizations getting the 3-7× click-through lift are the ones treating RCS as an upgrade path with an SMS floor, not a replacement channel.
What changed
RCS runs inside the phone's default messaging app: nothing to install, no new list to build. What it adds over SMS:
- Verified sender branding. Your name, logo, and a checkmark instead of a five-digit short code.
- True read receipts. SMS reports delivered. RCS reports read.
- Native rich content. Cards, carousels, and tap-actions in the thread, so there is no click-out to see the ask.
- Suggested replies. Structured responses instead of parsing free text.
The inflection point was Apple. Android has supported RCS for years; it only became worth planning around once iPhone joined with iOS 18.
What the numbers support
Click-through, published 2025 benchmark ranges
A 3–7× lift, on the same list. Ranges, not a single figure, because the four published sources disagree on the exact number.
Across published 2025 studies from CM.com, Sinch, Infobip, and Vonage, the pattern is consistent:
- 15-30% click-through on RCS against 4-7% on standard SMS: a 3-7x lift.
- 70-85% read rate, measured as actual reads rather than carrier delivery.
- 60-70% higher conversion from rich cards with images and tap-actions versus static MMS images.
- 74% of consumers report being more likely to engage with a brand over RCS than standard SMS.
Two cautions: these are global averages, and they skew toward commercial senders with strong creative. Treat the low end of every range as your planning number, which is what our lift calculator does by default.
What RCS still can't do
It doesn't reach everyone
Drag to match your own audience
This is why the SMS floor is not optional. Whatever the dial says, the remainder is the part of your list that hears nothing if you build RCS-only.
RCS needs a compatible phone, a carrier that has enabled it, and a user who hasn't turned it off. For most US programs in 2026 we see RCS-capable shares in the 60-75% band, varying enormously by audience; lists skewing older or lower-income skew lower.
This is the most important planning fact on this page. A campaign built RCS-only silently loses a quarter to a third of its audience.
Verification takes time
Verified sender status is an approval process, not a toggle. If you want RCS live for a fall campaign, the branding work starts in spring.
How to structure a program in 2026
One send, resolved per phone
The capability check happens at send time. Nobody is dropped, and nobody gets a broken message.
The architecture that works is not "move to RCS." It is one send, routed per recipient, with SMS as the floor:
- Check capability at send time. A capability flag captured six months ago is wrong.
- Set an SMS fallback window. Not read in time, it re-sends over SMS. Reach never drops below the SMS-only baseline.
- Design the message twice. The rich card and the 160-character version each have to stand alone.
- Report blended, then split. Leadership needs one number; optimization needs the cohorts separated.
- Use RCS where it converts. Rich media on the year-end appeal. Plain SMS on the receipt.
So what should you do
Add RCS to the program you already run; keep SMS underneath it. Measure the two cohorts separately for one full campaign cycle, and use your own numbers rather than anyone's benchmark table.
SMS is not going anywhere. It reaches every mobile phone on earth, and that property is worth more than rich cards. RCS is how you get more out of the people it can reach, which is most of them, and growing.
