iOS 26.5 Adds Encrypted RCS Messaging

iOS 26.5 brings end-to-end encrypted RCS messaging to iPhone users on supported carriers, closing one of the main privacy gaps in iPhone-to-Android texting.

What changes in iOS 26.5

The main update is support for end-to-end encrypted RCS messaging in beta. That means compatible RCS chats between iPhone and Android devices can now be protected so message content cannot be read in transit by Apple, Google, or the carrier handling the connection.

Why this matters

Before this update, iPhone users already had end-to-end encryption in iMessage conversations with other Apple devices. Cross-platform messaging with Android had improved after Apple added RCS support, but those chats still did not offer the same privacy level.

With iOS 26.5, RCS messaging now moves closer to the security standard many users expect from modern messaging services. It also keeps the practical RCS features that made cross-platform texting better than SMS, including read receipts, typing indicators, higher-quality media, and better group chat handling where supported.

How encrypted RCS works on iPhone

Encrypted RCS messaging is available only when the conversation meets the right conditions. The iPhone must be running iOS 26.5, the carrier must support encrypted RCS messaging, and the Android user must be on a current version of Google Messages with compatible support on their side.

When an RCS conversation is protected, the Messages app shows a lock icon and an encrypted status in the chat. Apple also lists the feature as on by default where supported, though rollout depends on carrier availability.

How to check the setting

On iPhone, the setting is found in Apps, Messages, and then RCS Messaging. Users can turn End-to-End Encryption (Beta) on or off there, but the feature only works when the network and the conversation both support it.

What this does not change

This update does not make every green-bubble conversation encrypted. SMS and MMS still do not get end-to-end encryption. Some RCS chats may also remain unencrypted if the carrier, device, or app version on either side does not support the full encrypted setup yet.

That means iPhone users still need to check the conversation status instead of assuming every message to Android is protected.

The bigger shift for cross-platform messaging

The update matters because it moves iPhone and Android messaging closer to a consistent standard based on the latest RCS profile. For people who use the default messaging app instead of a third-party service, this is one of the most practical privacy changes Apple has made for cross-platform texting.

For iPhone users following platform updates closely, iOS 26.5 is a meaningful release because it improves the security of everyday messaging without changing how the Messages app works.
