Apple and Google have finally buried the “green bubble” divide, launching end-to-end encrypted RCS messaging between iPhone and Android devices in a move set to reshape mobile privacy standards worldwide.

Rolling out in beta with Apple’s new iOS 26.5 update and the latest version of Google Messages, the feature secures cross-platform chats so messages can no longer be intercepted or read by Apple, Google, carriers or hackers while in transit.

The rollout marks the first time encrypted messaging has worked seamlessly between Apple and Android ecosystems.

Until now, iMessage chats between iPhones were encrypted, while Android users only had encryption within Google Messages conversations.

The upgrade is based on the GSMA’s new RCS Universal Profile 3.0 standard and Messaging Layer Security (MLS) protocol, developed through an unusual collaboration between Apple, Google and global telco partners.

Users will see a lock icon in chats confirming encryption is active.

The update also further closes the long-running “blue bubble versus green bubble” divide that has fuelled consumer backlash, social stigma and regulatory scrutiny around Apple’s messaging ecosystem.

Apple only adopted RCS support in 2024 after mounting pressure from regulators and rivals. Prior to that, texts between iPhone and Android users reverted to ageing SMS technology, often breaking group chats and downgrading photo and video quality.

The encrypted RCS rollout initially depends on carrier support, with major US telcos already onboard. Australian carrier support is expected to follow as operators adopt the updated RCS standard.
