Enhanced Security: iOS 26.5 Introduces End-to-End Encryption for RCS Messaging

iOS 26.5 has been officially released to the public after a six-week beta testing period. This update introduces new wallpapers, enhancements to Apple Maps, and various other features.

One of the key additions in iOS 26.5 is the support for end-to-end encryption for RCS messaging. Apple has mentioned that this feature is currently in beta and will be gradually rolled out over the next few months.

Apple initially introduced RCS support for the iPhone with iOS 18.1, allowing for more advanced messaging capabilities between iPhone and Android users. This included features such as typing indicators, read receipts, and the ability to send high-resolution photos and videos.

In March, Apple revealed its intentions to implement end-to-end encryption for RCS messages. The beta testing for this feature began with iOS 26.4 earlier this year, and now it is being made available to all users as part of iOS 26.5.

While RCS encryption is still labeled as a beta feature in iOS 26.5, it is enabled by default. Users have the option to toggle it on or off by navigating to Settings > Messages > RCS Messaging and locating the new “End-to-End Encryption (Beta)” toggle.

According to Apple, end-to-end encryption with RCS is currently supported by specific carriers and will be extended to more carriers in the future. A list of carriers that support RCS end-to-end encryption can be found on a dedicated webpage.

Apple emphasizes that the rollout of this feature will be gradual over the upcoming months. Even if a carrier is listed as supporting RCS end-to-end encryption, the feature may not be immediately available to all users of that carrier. As the rollout progresses, Apple assures that it will automatically enable the feature for both new and existing conversations.

Apple has also updated the Messages app interface to accommodate support for RCS encryption. When messaging someone with RCS encryption enabled, a new lock icon will appear at the top of the thread. Android users will also see this lock icon in their message threads, confirming the availability of the feature for their carrier and device.

The lock icon is now present in all iMessage threads as well, as iMessage has supported end-to-end encryption since 2011.

Apple’s implementation of end-to-end encryption support marks a significant advancement in its RCS capabilities. Users can update to iOS 26.5 by accessing Settings, selecting General, and then choosing Software Update.
