New cross-platform encryption for RCS messages: Android and iPhone users can now chat securely in beta
Breaking: End-to-end encrypted RCS now available across Android and iPhone in beta
After more than a year of delays, end-to-end encryption for Rich Communication Services (RCS) messages has finally arrived for both Android and iPhone users as part of a limited beta rollout. This update ensures that conversations between the two platforms are secured against third-party interception, closing a longstanding gap in cross-platform chat security.
“This is a huge step forward for private communication,” said Dr. Elena Russo, a cybersecurity researcher at the Digital Privacy Institute. “For the first time, the vast majority of mobile users can exchange encrypted messages without worrying about which operating system their contacts are on.”
Conditions and limitations
The encrypted RCS beta is not available to everyone. Users must have the latest versions of their respective messaging apps—Google Messages (Android) and Apple’s Messages app—and both parties must be enrolled in the beta program. Additionally, the feature currently works only for one-to-one chats, not group conversations.
Google confirmed the rollout in a blog post, stating that encryption is applied end-to-end using the Signal Protocol, the same technology behind WhatsApp and Signal. Apple has not yet commented publicly, but sources familiar with the matter say the company is testing the feature with a small percentage of users.
Background
RCS was developed as the modern successor to SMS and MMS, offering rich features like read receipts, typing indicators, and high-resolution media sharing. However, encryption was notably absent from the standard, leaving messages vulnerable to carriers and hackers.
Google has pushed for universal RCS encryption for years, and Apple finally adopted RCS in iOS 18 in 2024—but without end-to-end encryption. This led to calls from privacy advocates for stronger protections. The new beta addresses that concern, though only for those who opt in.
“Encryption should be a default, not an option,” said Mark Chen, a telecom industry analyst at TechMobility Research. “But this beta is a positive sign that both giants are willing to collaborate on security.”
What This Means
For everyday users, encrypted RCS means that private conversations between Android and iPhone users are now safer from eavesdropping—whether by hackers, carriers, or government surveillance. In an era of increasing digital threats, this adds a critical layer of protection.
However, the beta nature means many will not have access immediately. Users who frequently communicate across platforms may want to check their app settings or wait for the public rollout, which is expected later this year. Those who cannot wait can still rely on fully encrypted apps like Signal or WhatsApp.
Key takeaways
- Encryption is live in beta for RCS messages between Android and iPhone
- Both parties must be in the beta program to use the feature
- Only one-to-one chats are protected; group chats are not yet supported
- Signal Protocol provides the underlying encryption
As the beta expands, more users can expect secure messaging without needing third-party apps. Learn more about the history of RCS and what this means for your privacy.
