RCS messaging on iPhone

Apple's latest iOS 18 release includes Rich Communication Services (RCS),1 the industry text messaging standard. And that means texting friends and family will be smoother and clearer if they have a different operating system on their device.

Rich Communication Services (RCS) chats provide an upgraded, rich messaging experience. RCS chats: Show you when someone is typing. Offer read receipts, which show when someone has read or received your message. Read receipts also show your contact when you read their message.
