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.

Phone users cannot edit messages sent to Android smartphones and this is unlikely to change until Apple updates its Messages app.
