   Since RCS is cross platform, here's some cross-platform datapoints.   
      
   I get "most" of what's in RCS with PulseSMS, but of course, they're   
   different things altogether, but I do get group and individual naming.   
      
   RCS came with iOS 18, released in 2024.   
   Any iPhone that can run iOS 18 supports RCS such as the iPhone 11.   
   But none of the X iPhones support iOS 18, hence they don't have RCS.   
      
   RCS is NOT enabled by default on iOS.   
   Settings -> Apps -> Messages -> RCS Messaging   
       
      
   Caveats:   
    RCS only activates when messaging non-iMessage devices (e.g., Android).   
    RCS messages still appear as green bubbles, just like SMS/MMS.   
    Apple added RCS in iOS 18 (2024) & expanded features in iOS 18.1+
