Apple, Google drag cross-platform texting into the encrypted age

Apple and Google have taken a big step toward securing cross-platform texting, ending years of messages bouncing around in glorified plaintext. Apple announced this week that encrypted Rich Communication Services (RCS) messaging is rolling out in beta for iPhone users running iOS 26.5 and Android users on the latest version of Google Messages. The feature works across supported carriers and adds end-to-end encryption to cross-platform chats that were still taking the scenic route through carrier-era messaging infrastructure. Users will know it's enabled when a lock icon appears in RCS conversations. Apple says E2EE RCS messages cannot be read while traveling between devices, bringing Android-to-iPhone chats closer to the protections offered by WhatsApp and Signal. The move lands as other platforms head in the opposite direction. Earlier this month, Meta confirmed it was backing away from parts of its encryption rollout for Instagram DMs, telling The Register that "very few" people actually used the feature and suggesting privacy-minded users head over to WhatsApp instead. Apple, meanwhile, appears content to lean harder into the privacy angle, finally plugging one of the more obvious holes in modern messaging security. That gap has been hanging around for years. While iMessage chats between Apple devices were already encrypted, conversations involving Android phones could fall back to SMS or unencrypted RCS, depending on carrier support. Google had offered encrypted RCS chats inside Google Messages for years, but only when both sides used Google's ecosystem. Apple joining the party means cross-platform RCS encryption is finally starting to span the two largest mobile ecosystems. The rollout is still marked as beta, and carrier support varies by region, so not everyone will get encrypted chats immediately. UK availability remains unclear for now, as none of the major UK networks currently appear on Apple's published compatibility lists for the feature. Still, after two decades of the mobile industry insisting that interoperability and security could not coexist, cross-platform texting may finally be catching up with the rest of modern messaging. (R)
