Rich Communication Services (RCS) is a communication protocol between mobile telephone carriers and between phone and carrier, aiming at replacing SMS messages with a text-message system that is richer, provides phonebook polling (for service discovery), and can transmit in-call multimedia. It is part of the broader IP Multimedia Subsystem. Google has added support for end-to-end encryption for all chats using RCS in their own app, Google Messages. End-to-end encryption is not a feature of RCS specified by GSMA, instead deferring to the individual messaging clients to establish encryption.[1][2][3][4]
It is also marketed as Advanced Messaging,[5] and was marketed as chat features,[6] joyn, SMSoIP,[7] Message+, and SMS+.[8]
In early 2020, it was estimated that RCS was available from 88 operators in 59 countries with approximately 390 million users per month.[9] By November 2020, RCS was available globally in Google Messages on Android, provided directly by Google if the operator does not provide RCS.[10] By 2023, there were 800 million active RCS users on Google's platform and 1.2 billion handsets worldwide supporting RCS.[11]
