Apple added RCS support to iPhone with iOS 18.1, enabling richer cross-platform messaging between iPhone and Android users. This included things like typing indicators, read receipts, and high-resolution photo and video attachments.
Last March, Apple announced its plans to add support for end-to-end encryption for RCS messages.
Now, iOS 26.4 beta 1, which is rolling out today, adds an early way to test end-to-end encrypted RCS messaging on iPhone.
First, I want to note that what’s included in iOS 26.4 is a limited initial test of RCS end-to-end encrypted messaging that is meant for limited testing.
