Apple has expanded its messaging system with a major privacy upgrade for RCS chats. After years of demand, the company introduced RCS support in iOS 18 in late 2024. Since then, iPhone users have been able to message Android users with richer features than standard SMS.
However, one major limitation remained in place. These cross-platform RCS chats were not end-to-end encrypted. As a result, messages could be exposed while traveling between devices.
Now that limitation has finally been removed. With the rollout of iOS 26.5, Apple is enabling end-to-end encryption for RCS conversations. This update brings a significant shift in how secure messaging works between iPhone and Android users.
Google plays a key role in making this possible. The company confirmed that Android users on the latest version of Google Messages can now send encrypted RCS messages to iPhones running iOS 26.5. This improves interoperability between both platforms in a meaningful way.
Apple says this feature is supported only through specific carriers. The company has not made it available across all networks yet. However, support is expected to expand over time as carriers adopt the required standards.
End-to-end encryption means messages are protected from the moment they leave one device until they reach the other. No third party can read the content during transmission. This includes internet providers and platform intermediaries.
Users will notice a change in their chat interface as well. A lock icon now appears in RCS conversations that are protected with encryption. This visual cue confirms that the chat is secure. Encryption will be enabled by default for new conversations. Over time, existing chats will also be upgraded automatically to support this protection.
