Apple's iOS 26.5 update, released today, introduces initial beta functionality for end-to-end encrypted RCS messaging. Like other RCS implementations, this feature requires specific conditions from both the sender and receiver to ensure messages are protected during transmission.
Users need an iPhone updated to iOS 26.5 and linked to a network that enables end-to-end encryption via RCS. Apple's site lists all supported carriers. In the United States, AT&T, T-Mobile, and Verizon provide immediate compatibility. On the Android side, recipients must use the most recent Google Messages app on a device with access to a qualifying network.
iPhone users will notice a lock symbol appearing above RCS conversations when security is active. Apple states that this encryption activates automatically by default and will gradually apply to both ongoing and future RCS exchanges. Messages exchanged solely among Apple products will still utilize the iMessage system.
Alongside the iOS update, Apple has issued versions 26.5 for iPadOS, macOS Tahoe, and watchOS. The updates include limited new capabilities beyond the RCS enhancement, such as an enhanced Maps feature suggesting locations based on users' past queries and local popular spots. Additionally, a vibrant, adaptable 'Luminance' wallpaper with a Pride theme has been added.
This rollout addresses previous challenges in cross-platform messaging, allowing iOS and Android users to communicate securely via RCS without relying on external applications like Signal or WhatsApp. The development followed several years of efforts, including advocacy initiatives and regulatory influences from China, despite the persistence of distinct bubble colors in chats.
