Apple’s RCS Messaging Revolution: The End-to-End Encryption That’s Taking Forever to Arrive

Tech enthusiasts and iPhone users worldwide have been buzzing with anticipation about Apple’s long-promised upgrade to RCS messaging, but the reality check is finally hitting home: those revolutionary features we’ve been waiting for aren’t coming anytime soon.

The Great RCS Wait Continues

Remember when Apple dropped that bombshell announcement last March? The tech giant confirmed it would be embracing end-to-end encryption for RCS messaging in a future software update. At that time, iOS 18 was the latest and greatest, which naturally led everyone to assume these game-changing features would arrive with iOS 26.

Well, here we are, and the encryption revolution hasn’t materialized. But wait, it gets more complicated. The end-to-end encryption upgrade would have brought along a whole suite of other major improvements to the RCS protocol, and as of iOS 26.3 Release Candidate, every single one of these features remains conspicuously absent.

Breaking Down the RCS Evolution

Let’s rewind a bit to understand why this matters so much. When Apple first introduced RCS support with iOS 18, they went with the most basic version available – RCS 2.4. This stripped-down implementation handled only the bare essentials: read receipts, higher quality photos, and typing indicators. Most critically, it launched without any end-to-end encryption because, frankly, the open RCS standard didn’t support it yet. That crucial security feature didn’t arrive until RCS version 3.0.

Fast forward to last March, when Apple made that earth-shattering announcement to 9to5Mac. The company revealed it had spearheaded a cross-industry initiative to bring end-to-end encryption to the RCS Universal Profile published by the GSMA. The statement was clear and confident: “We will add support for end-to-end encrypted RCS messages to iOS, iPadOS, macOS, and watchOS in future software updates.”

The RCS 2.7 Goldmine of Features

While end-to-end encryption steals the spotlight, RCS version 2.7 brought an absolute treasure trove of features that would bring RCS messaging more in line with modern platforms like iMessage. We’re talking about features that have become standard expectations for digital communication:

• In-line replies that let you respond directly to specific messages
• Proper reaction support that actually displays emojis instead of clunky fallback text
• Custom reactions for personalized expression
• Message editing capabilities to fix those embarrassing typos
• Message deletion/recall functionality for when you send something you immediately regret

Currently, RCS on iPhone does support reactions, but in the most basic way imaginable. Instead of seeing a clean emoji reaction, you get a message that reads something like “User added x reaction to message” – hardly the seamless experience users expect in 2025.

The French Connection: Glimmers of Hope

Just when frustration was reaching its peak, something interesting emerged from the iOS 26.3 beta 2 testing phase. Some French carrier bundles hinted at something exciting: certain carriers would be able to enable end-to-end encrypted RCS messaging by default.

This discovery is significant for two reasons. First, it confirms that Apple is actively working on these features behind the scenes. Second, it suggests these much-anticipated RCS upgrades are likely coming very soon – potentially alongside the first iOS 26.4 betas later this month.

The new carrier bundles indicate that Apple is preparing for these features to be available relatively soon, though they won’t be part of iOS 26.3. This strategic rollout suggests Apple is taking a measured approach to ensure everything works flawlessly before the big reveal.

The Bigger Picture

This delay raises important questions about Apple’s strategy with RCS. Is the company being cautious about security implementation? Are there technical hurdles we’re not aware of? Or is this simply a case of ambitious timelines meeting the reality of complex software development?

What’s clear is that when these features do arrive, they’ll represent a fundamental shift in how iPhone users communicate with Android devices. The ability to edit, delete, and properly react to messages across the iOS-Android divide will eliminate one of the most frustrating aspects of cross-platform communication.
