What iOS 26.5 RCS encryption changes for iPhone and Android texts, including privacy limits, green bubbles, and message security.
iOS 26.5 introduced end-to-end encrypted RCS messaging in beta with supported carriers. That does not encrypt every green-bubble conversation. Check the actual conversation before relying on its protection.
Correction, September 5, 2026: updated the instructions and removed unsupported guarantees, release assumptions and testing claims. This guide follows the linked documentation.
The update has shipped
Apple’s iOS release history records the feature in iOS 26.5. Earlier wording on this page treated it as a future release. Carrier availability still rolls out over time, so an updated phone is only part of the requirement.
Look for the conversation indicator
Apple’s messaging guide describes an “Encrypted” label and lock icon at the top of an encrypted RCS conversation. A green bubble can also represent ordinary RCS, SMS or MMS. SMS and MMS are not end-to-end encrypted.
Check again if participants or messaging conditions change. Encryption protects a particular communication path; it does not prevent a recipient from sharing a message or make every aspect of the account anonymous.
Where to find the setting
Apple’s RCS setup instructions give the path Settings > Apps > Messages > RCS Messaging. The End-to-End Encryption beta option is on by default where supported. If RCS settings are missing, check your region and carrier support rather than assuming the phone is faulty.
Both sides matter
Your contact’s service must support the encrypted conversation too. Use Apple’s carrier feature directory and your carrier’s documentation to check the relevant service. We removed the previous claim that no supported-carrier list exists.
A successful one-to-one chat does not establish the status of a different group chat. Business messages and login codes can use other channels, so their presence in Messages does not make them encrypted RCS.
Confirm the recipient and the conversation’s indicator. If encryption is not established, choose a channel whose current protection you can verify. Do not use bubble color, a product’s reputation or a claim that another app is “always private” as a substitute for checking.
Our Apple Intelligence privacy guide covers a different data path. Messaging encryption does not describe how requests sent to an AI extension are handled.
