Enabling RCS on iPhone Running iOS 18: A Complete Guide

With the recent release of iOS 18, Apple has embraced the RCS (Rich Communication Services) messaging standard, facilitating seamless communication between iPhone and Android users. RCS introduces features such as read receipts, audio messages support, enhanced group chats, and other capabilities that were previously limited to iMessage. As the stable version of iOS 18 rolls out globally, more countries will gain access to RCS messaging support. If you’re eager to experiment with RCS on your iPhone, this guide will assist you in enabling it.

What Is RCS on iPhone

RCS, or Rich Communication Services, is an advanced messaging protocol designed to replace the outdated SMS/MMS system. Unlike SMS/MMS, which impose character and media constraints, RCS removes these limitations, allowing high-quality media sharing without character restrictions. With iOS 18, Apple has integrated RCS to improve communication between iPhone and Android users. The benefits of RCS in comparison to traditional SMS and MMS include:

Enhanced group chat capabilities
Support for audio messages
Read receipts feature
Typing indicators
Ability to share messages over cellular networks and Wi-Fi
Transmission of high-resolution photos and videos
Larger attachment file sizes
Improved encryption and privacy
Cross-platform emoji reactions
Location sharing within text conversations

How to Use RCS on iPhone

If you’ve updated your device to iOS 18 and your carrier supports RCS, enabling or disabling RCS on your iPhone is straightforward. Follow these steps:

Launch the Settings app on your iPhone.
Scroll down and select Apps.
Locate Messages by scrolling or using the search bar.
Select RCS Messaging and toggle the RCS Messaging switch to enable it.

That’s how to activate RCS on your iPhone with iOS 18. Major carriers in the US have been supporting RCS for some time, and now with the stable availability of iOS 18, many more carriers globally are expected to enable this feature.

Apple is also looking to collaborate with Google and other members of the Global System for Mobile Communications Association (GSMA) to enhance the RCS standard and introduce more advanced features, such as the capability to edit or undo sent RCS messages.
