Understanding RCS Messaging on iPhone in iOS 18

Rich Communications Services (RCS) messaging is an advanced protocol that aims to replace traditional SMS. Google implemented RCS for Android devices in 2019, while Apple only embraced it with the introduction of iOS 18 in September 2024, finally bringing RCS to iPhones.

What is RCS Messaging?

RCS stands for Rich Communications Service, a modern messaging protocol designed to replace outdated SMS technology. RCS allows users to share high-quality media effortlessly with friends and family. It also features typing indicators, message delivery and read receipts, and the ability to create group chats.

The RCS initiative began in 2007, but it wasn’t finalized until 2016. Although Google was the first to adopt RCS in 2019, Apple only incorporated this messaging standard with the advent of iOS 18 in 2024.

As a result, users on both iOS and Android platforms can now natively share various media files and utilize the rich features similar to those found in other popular messaging apps, including WhatsApp and Facebook Messenger.

How to Enable RCS Messaging on iPhone

To enable RCS Messaging on your iPhone, follow these steps:

Open the Settings app on your iPhone.
Scroll down and select Apps.
Next, scroll again and tap on Messages.
Look for the RCS Messaging option and toggle it on.

This setting will only be available if you are running iOS 18, so make sure to update your iPhone before following the above steps.

How to Check if Your Carrier Supports RCS Messaging

To determine if your carrier supports RCS Messaging, follow these steps:

Open the Settings app on your iPhone.
Scroll down and select General.
Next, tap on About.
Look for IMS Status. If it indicates Voice, SMS & RCS, your carrier supports RCS Messaging.
If the IMS Status shows only Voice and SMS without RCS, it means your carrier does not yet support RCS Messaging.

Even if your carrier currently lacks support for RCS Messaging, there is hope for future availability. While RCS Messaging holds great promise, it’s yet to be seen how well it will be accepted by iOS users.
