Secure RCS Messaging Between iPhones and Androids: A Step Closer

The long-awaited feature of end-to-end encrypted (E2EE) RCS messaging between iPhone and Android users is edging closer, with Apple's latest iOS beta hinting at significant progress.

Apple's Adoption of RCS Texting

Last year, Apple adopted RCS texting with the release of iOS 18, enabling iPhone and Android users to enjoy high-quality media, text reactions, richer group chats, and more. However, RCS conversations between these devices lacked E2EE security.

GSMA's Universal Profile 3.0 Specifications

In March, the GSMA announced new Universal Profile 3.0 specifications for RCS, which included E2EE based on the Messaging Layer Security (MLS) protocol. This protocol would allow Apple to introduce interoperable E2EE to its RCS chats.

Discovering the New Setting

Recently, a leak by X (formerly Twitter) user @TiinoX83 revealed that Apple is laying the groundwork for E2EE in iOS 26.3 Beta 2. Upon checking carrier bundles for iOS 26.3 beta 2, the leaker found a new setting that allows carriers to enable encryption for RCS.

Carriers Involved

Interestingly, only four French carriers (Bouygues, Orange, SFR, and Free) have this line of code, and none of them have activated it yet.

Implications for North East India and Beyond

The potential implementation of E2EE RCS messaging holds significant implications for privacy-conscious users across the globe, including those in North East India. Secure cross-platform communication would allow users to communicate with more freedom and confidence, regardless of their device choice.

What's Next?

It's expected that Apple will release the final version of iOS 26.3 later this month. While it's looking unlikely that iOS 26.3 will be the update that brings the long-awaited privacy feature, the discovery of this new setting is a promising sign that the future of secure RCS messaging is getting closer.
