More than 100 millions users have downloaded and used the messaging app called "Android Messages" from Google to replace their default SMS texting services. It has latest version of RCS (Rich Communication Service), the next-generation messaging standard supported by GSMA (a group of international carriers).
The "Android Messages" offers multimedia messages (SMS &+ MMS), read receipts, send group texts, share your favorite pictures, videos, and audio messages, wifi connectivity, and you’ll be able to enjoy all the features of WhatsApp, Facebook Messenger, iMessage, and WeChat without having to create another account, or sign into a social network (see the link "What is RCS messaging?" below).
