RCS Rich Cards are changing what's possible inside a text message thread, and if you're still sending MMS to drive conversions, you're leaving serious revenue on the table. I hear this from customers constantly: they've spent years optimizing MMS creatives, tweaking image sizes, testing copy, and the needle barely moves. Then they run their first RCS campaign with Tells and the results look like a reporting error. They're not.
RCS Rich Cards vs MMS: What's Actually Different
MMS is a photo with a caption. That's it. You're sending a static image and hoping the customer does the mental work of figuring out what to do next. RCS Rich Cards are interactive mini-apps that live inside the message thread. We're talking about a carousel of products, a high-res image, a title, a description, and action buttons, all in one unit, delivered natively in the default Messages app on Android.
There's no app to download. No link to tap and hope the landing page loads fast enough. The experience is self-contained, and that frictionless path is exactly why RCS conversion rates run roughly 3x higher than comparable MMS campaigns in early rollout data we've seen across Tells customers.
Buttons That Do the Work for You
Here's the part that still surprises people when they see it for the first time. Inside a single Rich Card, you can stack multiple call-to-action buttons that each trigger a different outcome.
- Tap-to-buy that opens a pre-filled cart or checkout flow
- Tap-to-call that dials your team or our Gideon voice AI agent instantly
- Tap-to-reply that kicks off a two-way conversation inside the thread
- Suggested replies for quick qualification or survey responses
This matters because different customers are at different stages of intent. One person is ready to buy. Another wants to talk to someone. Another has a question. A Rich Card lets you meet all three in the same message. An MMS image cannot do any of that. Learn more about how Tells messaging solutions connect these touchpoints across the full customer journey.
The Trust Signal Most Brands Underestimate
One thing I'm genuinely opinionated about: verified sender identity is the most underrated conversion lever in mobile messaging right now. We spent months working through the RCS Business Messaging approval process because we knew that verified badge next to a brand name would fundamentally change how customers engage with commercial messages.
When a Rich Card arrives from a verified business sender, the customer sees the brand logo, the verified checkmark, and a rich media experience all at once. That's a trust signal carriers respect and customers respond to. Compare that to a 10-digit number sending an MMS with a URL that looks like it could be phishing. The gap in perceived legitimacy is enormous.
Tells is one of the first US platforms fully approved for RCS Business Messaging. That approval process exists for a reason, and it's part of why our customers can send at scale without deliverability issues. You can review our approach to compliance and security standards if that's a factor in your evaluation.
What Early RCS Campaign Data Actually Shows
I want to be specific here because vague claims don't help anyone make a decision. Across early Tells RCS campaigns in retail and financial services:
- Click-through rates on Rich Card action buttons averaged 35-40% higher than MMS link clicks in the same segments
- Tap-to-call conversions from Rich Cards connected customers to live agents or Gideon AI at a rate roughly 2.8x that of SMS-only campaigns with a phone number in copy
- Customers who engaged with a carousel Rich Card showing multiple products had a 22% higher average order value compared to single-image MMS
These aren't outliers. They reflect what happens when you remove friction and add context. The Tells insights blog will have more campaign breakdowns as we publish them. For broader RCS adoption benchmarks, GSMA's RCS resource hub is worth bookmarking.
How to Think About MMS vs RCS in Your Channel Mix
MMS isn't dead. For short, simple alerts where the image is purely decorative and the action is obvious, it still has a place. But for any campaign where you want to drive a specific conversion action, build brand trust at the moment of delivery, or serve customers with different intent signals in the same send, Rich Cards are the better tool.
The practical question is reach. RCS currently covers Android's default Messages app, which represents a very large share of US smartphone users. If your audience skews Android, the case for shifting budget to RCS is strong today. If you have a mixed iOS/Android base, Tells handles the fallback logic automatically, so Android users get the Rich Card experience and others get a well-formatted SMS or MMS, no extra work on your end.

Frequently Asked Questions
What are RCS Rich Cards and how are they different from MMS?
RCS Rich Cards are interactive message units that include high-res images, titles, descriptions, and action buttons like tap-to-buy or tap-to-call, all delivered inside the native Messages app. MMS is a static image with a caption and no native interactivity. Rich Cards give customers a way to act on an offer without leaving the thread.
Why do RCS Rich Cards convert better than MMS?
The main reasons are reduced friction, verified sender trust signals, and native interactivity. Instead of tapping a link and waiting for a page to load, customers tap a button that triggers an action instantly. Combined with a verified brand badge, the experience builds confidence that drives higher intent actions at the moment of receipt.
Is RCS available across all US carriers and devices?
RCS Business Messaging is supported on Android devices using the default Google Messages app, which covers a large share of US Android users. All four major US carriers support RCS. iOS support via Apple Messages for Business exists separately. Tells handles carrier fallback automatically so your campaign reaches everyone appropriately.
How does Tells handle RCS Business Messaging approval?
Tells is one of the first US platforms approved for RCS Business Messaging. We manage the brand verification and sender registration process on behalf of customers, which includes working with carriers to get the verified sender badge applied to your business profile before your first send.
Can I use RCS Rich Cards with Gideon, the Tells voice AI?
Yes. A tap-to-call button inside a Rich Card can connect directly to a Gideon AI agent, creating a seamless handoff from a visual message experience to a live voice conversation. This is particularly effective for high-value offers where customers want to ask questions before committing.
