RCS rollout in iOS 18 to bridge Apple & Android messaging gap

Apple is set to replace an aging text messaging protocol with a newer one to improve compatibility with Android. Here’s when it will be deployed.

RCS, or Rich Communication Services, is an upgrade to a smartphone’s traditional text messaging (SMS) system. This makes text messages more like iMessage with iOS 18.

The RCS messaging protocol supports features like seeing when someone is typing, sending high-quality images and videos, and knowing when messages are read. Unlike the old SMS, RCS can use Wi-Fi and cellular data, making it more versatile and user-friendly.

Apple’s decision to adopt RCS comes after years of reluctance. In 2022, Apple CEO Tim Cook remarked that RCS was “not a priority” for the company.

However, increasing regulatory pressures and the need for better interoperability have influenced this change. The European Union, for example, asked Apple to open iMessage to other platforms, which accelerated Apple’s decision to adopt RCS.

Although RCS improves cross-platform communication, it will not replace iMessage. Apple’s iMessage will remain the primary messaging platform for iPhone-to-iPhone communication, retaining its blue bubbles. RCS messages, on the other hand, will appear as green bubbles, much like current SMS and MMS messages.

When will RCS roll out to iPhone

Apple said in its WWDC 2024 announcement on Monday that support for RCS would be introduced in a software update later in the year.

However, this may not coincide with the initial release of iOS 18. Users might see RCS features become available in later updates.
