SMS is already your customers' preferred channel. RCS makes it smarter.
RCS Business Messaging delivers rich cards, images, and interactive buttons inside the native messaging app — no third-party app, no account, no friction.
SMS is the channel your customers already use
Most support channels require app downloads or account logins. SMS requires nothing — it's already on every phone. RCS gives you the same frictionless reach with rich media and interactive buttons on top.
Rich messaging is now mainstream
RCS works on Android via Google Messages and on iOS 18.2+. Coverage is no longer a reason to delay. For devices that don't support RCS yet, automatic SMS fallback means every customer gets a reply.
Customers expect instant answers — even by text
Whether someone texts about your hours, a product, or a booking, they expect a response in seconds. A VocUI RCS chatbot answers instantly from your knowledge base — around the clock.
Connect your knowledge base to RCS in three steps
Train on your business docs
Upload your FAQs, product documentation, service pages, and policies. VocUI indexes everything and makes it queryable by AI in natural language.
Connect your Twilio RCS sender
Link your Twilio account with RCS Business Messaging enabled. VocUI configures the webhook so inbound RCS messages are answered by your AI automatically.
Reply with rich cards and answers
Customers text in naturally. VocUI responds with accurate answers from your knowledge base — and for RCS-capable devices, delivers rich cards, images, and suggested reply buttons.
Everything your RCS business agent needs
Rich media for supported devices. Plain SMS fallback for everyone else. One knowledge base powering both — no separate setup required.
Rich cards and suggested replies
Send image carousels, action buttons, and quick-reply chips — capabilities that standard SMS can't match. RCS turns your chatbot into a native app-like experience.
Automatic SMS fallback
When a device doesn't support RCS, VocUI automatically falls back to plain text SMS. Every customer gets a reply — regardless of their device or carrier.
Trained on your content
Upload PDFs, URLs, product docs, and policies. Your RCS bot answers from your actual documentation — not generic AI guesses.
Works in the native messaging app
No app download. No account creation. Customers interact in the same app they already use to send texts. RCS with VocUI removes every barrier to support.
Verified business sender
RCS Business Messaging displays your brand name and logo in the conversation thread — not just an anonymous phone number. Customers know they're talking to you.
Usage analytics
See which questions get asked most and which go unanswered. Use the data to improve your knowledge base and close coverage gaps over time.
What businesses use VocUI RCS for
Any business that already uses SMS for customer communication can upgrade to RCS and start delivering richer, faster support at no additional setup cost.
Customer support
Answer inbound product questions, order status requests, and policy FAQs via RCS — instantly and at scale, without a support agent.
Sales and pre-purchase
Let prospects ask about pricing, features, and availability by text. Your RCS chatbot qualifies interest and captures leads before handing off.
Multi-channel reach
The same VocUI knowledge base powers your RCS agent, SMS fallback, and website widget. One source of truth across every channel.
Appointment reminders and follow-ups
Confirm bookings, answer pre-appointment questions, and follow up post-visit — all through RCS with rich action buttons for easy rescheduling.

Common questions about VocUI RCS chatbot
Do I need a Twilio account to use the RCS chatbot?
Yes. VocUI connects to your existing Twilio account with RCS Business Messaging enabled. You bring the Twilio sender — VocUI provides the AI that answers inbound messages from your knowledge base.
What happens when a user's device doesn't support RCS?
VocUI automatically falls back to standard SMS for devices that don't support RCS. This includes older Android devices and iPhones running iOS below 18.2. Your chatbot keeps working — just without the rich media features.
Which devices support RCS?
RCS is supported on Android devices running Google Messages, and on iPhones running iOS 18.2 or later. Via Twilio, RCS Business Messaging is currently live in the United States, United Kingdom, and Canada. Customers in other regions — including Australia, where carriers are not yet live on Twilio RCS — automatically receive standard SMS fallback.
Can I send rich cards and images through the RCS chatbot?
Yes. RCS supports rich cards, image carousels, suggested reply buttons, and action buttons — capabilities that standard SMS cannot deliver. VocUI uses these features when responding to RCS-capable devices.
Can the same VocUI chatbot handle both RCS and SMS?
Yes. One VocUI knowledge base powers your RCS business agent with automatic SMS fallback. Train once and your chatbot serves all users — rich experience for RCS devices, plain text for everyone else.
