Does RCS work on iPhone?
RCS on iPhone became available with the release of iOS 18 on September 16, 2024, introducing richer messaging features to conversations between Apple and Android devices. Apple first announced support for RCS during WWDC on June 10, 2024, marking a shift toward improved cross-platform messaging.
Rich Communication Services (RCS) is a modern messaging standard designed to enhance traditional SMS and MMS. With RCS on iPhone, users can now exchange higher-quality media, see typing indicators, and receive read receipts in conversations with Android users. Beyond person-to-person communication, the introduction of RCS on iPhone also expands the reach of RCS business messaging, enabling brands to deliver richer application-to-person (A2P) messaging experiences.
In this article, we explain how RCS on iPhone works, what features it offers, and why its introduction is important for the future of messaging and business communication.
What is RCS on iPhone?
RCS on iPhone refers to Apple’s support for Rich Communication Services messaging introduced with iOS 18. RCS is designed to upgrade SMS and MMS with richer messaging features while still using the native messaging app on mobile devices.
When iMessage is not available, iPhones can now use RCS instead of SMS when communicating with Android devices that support the same standard.
Messages sent using RCS on iPhone appear as green bubbles in the Messages app but offer more advanced capabilities than standard SMS.

RCS on iPhone and RCS business messaging
The introduction of RCS on iPhone has important implications for RCS business messaging, particularly in the A2P (application-to-person) messaging space.
