For years, rich mobile marketing was divided: Android users could receive rich RCS messages, while iPhone users were restricted to standard SMS. This fragmentation forced brands to rely on third-party apps like WhatsApp or return to low-engagement text messages. Apple's support for RCS in iOS 18 has completely transformed the messaging ecosystem.
1. The Frictionless Rich Experience
Unlike WhatsApp or Telegram, which require the customer to download an app and set up an account, RCS works natively inside the default messaging app on the phone. When a brand sends an RCS message, it appears directly in the native inbox, complete with high-res images, carousels, and verified branding. It delivers the utility of an app without the download barrier.
2. Building Trust with Verified Senders
RCS establishes sender verification through carrier-level certificates. Instead of an anonymous phone number or standard short code, customers see your verified brand name, custom logo, and a blue verification badge. This visual trust increases response rates and click-through rates (CTR) by over 40% compared to SMS.
3. Suggested Actions and Interactive Conversational Flows
Underneath an RCS card, you can configure interactive buttons: "Add to Calendar", "Open Maps", "Call Support", or predefined quick replies. This allows users to complete multi-step journeys—like booking a service or checking a flight status—in one tap without leaving their texting app.
