RCS is an upgrade to regular texting that adds features like read receipts, typing indicators, reactions, clearer photos and videos, group chats, and messaging over Wi-Fi. These features work when both you and the person you’re messaging have RCS. If they don’t, your message will still send as a regular text.
Starting November 9, RCS will start to be available on some Optimum Mobile Android phones. It will be added to more phones over the following weeks.
RCS for iPhone is coming later, and we’ll let you know when it’s available.
