Summary:

• **What is RCS Messaging?** RCS is a new way for phones to send messages to each other that is more advanced than regular text messages. Apple is working on making RCS messages extra secure by using end-to-end encryption, which means only the person sending and receiving the message can read it—nobody else can see what you're saying.

• **Why is Apple Testing This?** Apple is testing this new feature in iOS 26.4 beta, which means they're trying it out before letting everyone use it. This helps them make sure the encrypted messaging works properly and keeps people's private conversations safe from hackers or people trying to spy on their messages.
