Here’s a game-changer in the world of messaging: Apple is finally testing end-to-end encryption for RCS, but there’s a catch that might leave Android users feeling left out. While this move promises to bring Apple’s phone-number-based texting up to par with Google’s RCS and its own iMessage in terms of security, it’s not all smooth sailing—yet.
But here’s where it gets controversial: Apple’s RCS encryption, currently available in the first iOS 26.4 developer beta, only works between iPhones. That’s right—if you’re texting between an iPhone and an Android device, your messages won’t be encrypted, even though Apple has laid the groundwork for this feature. This limitation has sparked debates about whether Apple is prioritizing its ecosystem over cross-platform compatibility. And this is the part most people miss: Apple’s RCS encryption relies on the newer RCS Universal Profile 3.0, which includes E2EE, but the company initially rolled out RCS using the older version 2.4, which lacks these protections.
Let’s break it down further. Since iOS 18.1, RCS has allowed Apple to offer richer messaging features like typing indicators, read receipts, and higher-quality media for non-iMessage chats (those infamous green bubbles). However, cross-platform encryption has been the missing piece of the puzzle. Android users have enjoyed secure RCS chats for a while, but Apple’s initial RCS implementation didn’t extend end-to-end protection beyond its own devices.
With iOS 26.4, Apple isn’t fully launching RCS E2EE just yet. Instead, it’s in the testing phase. A new toggle in Settings, enabled by default for developers, lets compatible carriers and devices experiment with E2EE. Even with this switch turned on, encrypted chats are limited to iPhone users who have iMessage turned off—a detail that might frustrate those hoping for seamless Apple-to-Android encryption.
Apple has confirmed that full RCS E2EE won’t debut with iOS 26.4 but will arrive in a future software update across iOS, iPadOS, macOS, and watchOS. While this delay might disappoint users eager for secure cross-platform texting, it’s undeniably a step in the right direction.
Here’s the thought-provoking question: Is Apple’s gradual rollout of RCS encryption a strategic move to keep users within its ecosystem, or is it simply a technical challenge that takes time to resolve? Let us know your thoughts in the comments—we’d love to hear your take on this evolving story.
