However, end-to-end encryption is not available completely but will start rolling out to beta testers beginning this month and will continue into next year. I love that they're offering RCS via their app after dealing with so much headache from phone carriers - these companies generally want you to use their RCS features in their own branded messaging apps that come as bloatware on most phones and it's so frustrating. The E2EE feature is now not available for SMS/MMS as well as in group messaging.
After several years of failing to make RCS widely available, due primarily to pushback by phone carriers, Google has now officially made their Rich Communication Services or RCS available globally via their Messages app. To sing up to test out end-to-end encryption follow the instructions here and wait for the update to arrive on your device.
Previously, it was only available in a few countries, including France, Mexico, and the US.
As Google explains it, RCS upgrades SMS text messaging so that users can send and receive better quality photos and videos, chat over Wi-Fi or data, know when messages are read, share reactions, and enjoy more dynamic and engaging group chats.
