After years of green bubbles and privacy compromises, Apple and Google have finally done what should have happened a decade ago: texts between iPhone and Android users can now be end-to-end encrypted.
This is genuinely good news. It's also about five years late.
What Changed
Starting with the latest updates to iOS and Android, cross-platform messages will use the RCS (Rich Communication Services) protocol with end-to-end encryption enabled by default. That means messages between an iPhone user and an Android user are encrypted in transit and can only be read by the sender and recipient—not by Apple, Google, or carriers.
Previously, these messages fell back to SMS, the ancient text messaging protocol from the 1990s that sends messages in plain text. Anyone with access to carrier infrastructure—telecom employees, law enforcement with a warrant, or hackers who've compromised cellular networks—could potentially intercept and read them.
For context: WhatsApp, Signal, and even Facebook Messenger have offered end-to-end encryption for years. But default text messaging between the two dominant mobile platforms didn't. It was an embarrassing gap in consumer privacy.
Why Did This Take So Long?
The short answer: Apple didn't want to do it.
The longer answer is more complicated. iMessage, Apple's proprietary messaging system, has been end-to-end encrypted since 2011. It's one of the iPhone's selling points, especially for privacy-conscious users.
But iMessage only works between devices. When an user messages an user, the message falls back to —hence the infamous that indicate you're texting an outsider.
