Apple and Google Launch Beta Rollout of End‑To‑End encrypted RCS messaging across iOS and Android

Apple and Google have officially begun rolling out end‑to‑end encrypted Rich Communication Services (RCS) messaging in beta for iPhone and Android users, marking a historic upgrade to cross‑platform texting security. Starting with iOS 26.5 and the latest Google Messages, conversations between iPhone and Android devices will now be encrypted by default, ensuring that only sender and receiver can read messages.

What’s New in RCS Encryption

• Cross‑platform security: For the first time, iPhone‑to‑Android RCS chats are end‑to‑end encrypted, preventing carriers, tech companies, or third parties from accessing messages.
• Default protection: Encryption is automatically enabled for new and existing RCS conversations; users will see a lock icon in chats to confirm security.
• Beta rollout: Available now for iPhone users on iOS 26.5 with supported carriers and Android users on the latest Google Messages app.

Industry Collaboration

• Apple & Google partnership: Both companies worked with the GSMA to integrate encryption into the RCS Universal Profile 3.0 standard.
• Security protocol: The system is built on the Messaging Layer Security (MLS) protocol, a modern cryptographic framework designed for scalable, secure messaging.
• Statements from leaders: Google’s Android head Samer Samat called it “Big news” and a “terrific milestone.” Sundar Pichai and Rick Osterloh praised the achievement. Apple emphasized that iMessage remains fully encrypted.

Features Beyond Encryption

• High‑quality media sharing (photos, videos)
• Typing indicators & read receipts
• Improved group chats
• Cross‑platform reactions and inline replies

Comparison: SMS vs RCS vs iMessage

SMS	RCS	iMessage
Basic text only	Rich media, group chats, reactions	Rich media, stickers, apps
No encryption	End‑to‑end encryption (beta rollout)	End‑to‑end encryption (default)
Carrier‑dependent	Internet‑based, cross‑platform	Apple ecosystem only
No read receipts	Read receipts, typing indicators	Read receipts, typing indicators

Key Takeaways for Users

• Update required: iPhone users must install iOS 26.5; Android users need the latest Google Messages.
• Carrier support: Both sender and receiver must be on carriers supporting the latest RCS profile.
• Gradual rollout: Encryption will expand automatically to all conversations over time.
