Twilio announced the general availability of Rich Communication Services (RCS) messaging globally.
Twilio's RCS enables brands to send branded, verified messages with rich interactive features—marking the biggest leap in business messaging since SMS. Following the public beta launch last year, RCS is now available to all 349k+ active customer accounts through Twilio's Programmable Messaging and Verify APIs.
Existing customers are able to upgrade with no code changes and new customers can implement both SMS and RCS through a single integration via the Twilio platform.
Following the successful partnership with Singtel earlier this year, which marked Singapore as the first country in Asia where Twilio offered RCS Business Messaging (RBM), the platform paves the way for enterprises to elevate customer engagement through richer, more trusted interactions.
Key capabilities of Twilio’s RCS include:
Branded Messaging: Automatically upgrades SMS messages to RCS on capable devices at no additional cost for basic messages up to 160 characters, with business logos, taglines, and trusted sender verification by Google.
Rich Content and Interactive Features: Enables call-to-action buttons, interactive carousels, location sharing, and rich media content that drive higher engagement and conversion rates.
Seamless Integration: Simple configuration through the Twilio Console with automatic carrier management.
SMS Fallback: Twilio’s platform automatically detects when RCS is unavailable and seamlessly falls back to SMS, ensuring reliable message delivery without any additional configuration.
With messaging fraud reaching epidemic proportions and consumer skepticism at an all-time high, branded communications, along with real-time personalization, have become essential for building customer trust. According to Twilio’s 2025 State of Customer Engagement Report, while 90% of consumers trust at least some brands, just 15% absolutely trust them with their data. Additionally, 88% of consumers are more likely to buy when engagement is personalized in real time—but only 44% of brands say they’re executing at that level.
RCS can help address this trust gap by ensuring customers always know who they are communicating with through verified company branding, business logos, and trusted verification badges. This makes RCS particularly valuable for transactional communications like order confirmations and delivery updates, marketing campaigns with rich media content, and customer service interactions requiring quick replies—all areas where brand trust and engagement are critical. Through Twilio's platform, this can enhance trust and translate into measurable business results, as businesses using RCS experience a 32% increase in customer engagement and conversion rates compared to traditional SMS messaging, according to a recent study by Futurum Research.
Existing Twilio Messaging customers can upgrade to RCS without code changes, adding an additional channel option alongside SMS, MMS, and WhatsApp, while new customers can implement both SMS and RCS messaging through a single API integration. Twilio manages registration and onboarding with carriers, device capability checks, and provides automatic fallback to SMS when RCS is not available, ensuring reliable message delivery for any business at any scale.
Following Apple's support for RCS on iPhones starting with iOS 18.2 in December 2024, Twilio's RCS messaging is now available globally across 20+ countries and 55+ carriers. This expanded reach across both major mobile platforms positions RCS for widespread enterprise adoption, with customers like Nova Gestões in Latin America and Fresha in Europe already leveraging RCS to enhance their customer communications.
Businesses ready to transform their customer engagement with branded, interactive messaging can get started with RCS through the Twilio Console today.

The significance and potential of RCS goes beyond just uplift – the capability will help reshape business messaging into an interactive, trusted, and transaction-ready channel. What was once a one-way notification system is becoming a two-way enriched workflow – one where payments, authentication, and service requests can be completed without leaving a messaging app. For businesses, this means faster transactions, lower customer effort, and new opportunities to drive loyalty, revenue and better experiences. Zero-code setup and built-in SMS fallback capabilities are important in helping businesses overcome common adoption hurdles, including rollout and integration complexities, to ensuring messages can still be received even if RCS isn’t supported.
