On 11 May 2026 Apple began rolling out end-to-end encryption for RCS messages in iOS 26.5. RCS is the standard that carries the modern bits of a cross-platform chat — full-quality photos, typing indicators, read receipts — between an iPhone and an Android phone.
What actually changed
Until then those messages were protected only between handset and server, which left an intermediary technically able to read them. The specification the GSMA published on 14 March 2025, as part of Universal Profile 3.0, applies the Messaging Layer Security protocol so that messages and attached files stay closed between the two handsets. The GSMA calls it the first large-scale messaging service with interoperable encryption between clients built by different companies.
Apple says the protection is on by default and shows a small lock inside the conversation.
The catch for Kuwait
It only works if the network operator on both ends supports it. Apple’s own carrier page for the Middle East and India lists three companies in Kuwait: Zain, Ooredoo and stc. What each is credited with is 5G, eSIM, VoLTE, FaceTime over cellular and Wi-Fi calling. RCS is not on any of those three lists at all, never mind encrypted RCS.
Across the whole region the same page shows RCS for exactly one operator, Reliance Jio in India. Saudi and Emirati operators are absent too.
What it means in practice
Message an Android phone from an iPhone in Kuwait and the message most likely travels as an old-fashioned text or picture message, not as a locked RCS chat. That is also why typing indicators vanish and photo quality collapses in exactly those threads.
To check a specific conversation on an iPhone: Settings, then Apps, then Messages, then RCS Messaging, and look at the encryption switch. Then open the thread, tap the contact’s name or photo at the top, and scroll to the bottom. The line there states plainly whether the conversation is encrypted end to end, or whether it is not.
Until the local operators appear on that list, an app that does its own locking — rather than relying on the network — remains the dependable way to keep a cross-platform thread closed.
