For years, texting between an iPhone and an Android device was a bit like sending a postcard instead of a sealed letter. Anyone with the right tools and position along the route could theoretically read what you wrote. That changes today. Apple and Google have jointly rolled out end-to-end encrypted RCS messaging in beta, and it marks one of the most significant upgrades to cross-platform private communication in the smartphone era.

What Is End-to-End Encrypted RCS Messaging and Why Does It Matter?
Rich Communication Services, better known as RCS, is the modern successor to the humble SMS text message. It brought features like read receipts, typing indicators, and high-quality photo sharing to Android-to-iPhone conversations when Apple added RCS support with iOS 18 back in September 2024. But security was the gaping hole in the story. Until now, those messages could theoretically be intercepted in transit.

End-to-end encrypted RCS messaging closes that gap. When encryption is active, messages are scrambled the moment they leave your device and can only be unscrambled by the recipient’s device. Not your carrier. Not a government agency. Not even Apple or Google. Nobody in the middle gets to read what you sent.
iPhone users running iOS 26.5 with supported carriers and Android users on the latest version of Google Messages are now beginning to receive this protection in a beta rollout. The encryption is switched on by default, so most users will not need to dig through any settings to benefit from it.
How to Know Your RCS Chat Is Encrypted
The visual cue is refreshingly simple. A small lock icon now appears in RCS chats to indicate that the conversation is end-to-end encrypted. On iPhone, the Messages app will display “Text Message · RCS | Encrypted” alongside that lock icon. Android users in Google Messages will see the same familiar lock symbol they already knew from existing encrypted RCS conversations.
If you want to double-check your settings on iPhone, head to Settings, then Messages, then RCS Messaging, and confirm that “End-to-End Encryption (Beta)” is enabled.
The Technical Backbone
This is not a simple software patch. Apple and Google worked with the GSM Association to implement end-to-end encryption for RCS messages. The encryption is part of the RCS Universal Profile 3.0, published with Apple’s involvement and built on the Messaging Layer Security protocol. The MLS protocol is an open standard developed specifically for group and one-to-one messaging security, and its use here signals that this encryption is built to last and scale.
RCS Universal Profile 3.0 also includes editing and deleting messages, cross-platform Tapback support, and replying to specific messages inline during cross-platform conversations. In other words, the upgrade is about much more than just locking your texts.
Which Carriers Support It in the US?
Both the sender and the receiver need to be on a carrier that supports the latest version of RCS for encryption to activate. In the United States, major carriers including AT&T, T-Mobile, Verizon, Boost Mobile, Cricket, Mint Mobile, Consumer Cellular, Cox Mobile, US Cellular, Visible, and Xfinity Mobile are among those with day-one support. The list is long, covering a substantial majority of US subscribers from day one.

In Canada, carriers including Rogers, Bell, Telus, Freedom Mobile, Koodo, Virgin Mobile, Public Mobile, and Videotron are among those supporting the feature. The rollout is phased, and encryption will automatically activate for both new and existing RCS conversations over time as more carriers come on board globally.

What About iMessage?
Apple is careful to note that iMessage, used for Apple device-to-Apple device communication, has always been end-to-end encrypted and remains its flagship secure messaging platform. The new encrypted RCS feature specifically addresses the iPhone-to-Android blind spot that has existed since the dawn of cross-platform texting.
Apple initially announced it would add end-to-end encryption to RCS messaging in March 2025, with developer beta testing beginning in early 2026 before today’s wider rollout with iOS 26.5. The journey from announcement to public beta took a little over a year, a timeline that reflects the complexity of coordinating a cross-industry standard across multiple carriers, operating systems, and regulatory environments worldwide.
Requirements at a Glance
To use end-to-end encrypted RCS messaging today, iPhone users need iOS 26.5 and a supported carrier. Android users need the latest version of Google Messages and a supported carrier. Both parties in a conversation must meet these requirements for the encryption to activate.
A Small Lock, a Giant Leap
Billions of text messages are sent every day between iPhone and Android users, and for most of that history, those messages travelled with considerably less privacy protection than a sealed envelope. Today’s update does not solve every privacy question in mobile communications, and the beta label is a reminder that the rollout will take time to reach full maturity. But the direction is unambiguous. Apple and Google, two companies that often seem determined to remain in parallel universes, have actually teamed up to protect your texts. Lock icons have never looked more reassuring.
