According to Android Authority, this new Google Messages RCS feature works when texting iPhone users with iOS 18.5 and the iOS 26 beta, in both individual chats and group chats. Like editing messages to other Android users, you'll have a 15-minute window to edit the text after it has been sent. After that, you'll no longer be able to edit it.

Did you know that Google Messages actually supports text formatting? Unfortunately, though, this feature isn't available to users.

You’ve been able to edit texts sent between iPhones for years, and messages going from one Android device to another have been editable when using RCS for about twelve months. But although editable messages are now part of RCS, companies like Apple and Google need to support the feature – which is why it’s not available in iOS right now.
