A new revolutionary technology is coming to mobile phones as people are getting bored with the standard SMS (Short Message Service).
What is RCS?
RCS is a new online agreement that was chosen for adoption by the GSM Association in 2008. RCS is the replacement of the SMS which has been part of mobile phones since 1990s. GSMA is the organization which represents the interests of mobile operators worldwide, uniting more than 750 operators with over 350 companies in the broader mobile ecosystem.
Advantage of RCS over SMS:
RCS will add multimedia sharing ability to your plain texting over SMS, it will help you share GIF, Photos and Videos. It will also let you know if the receiver is available to receive the message and will send you a receipt that the receiver have received the message. It will also let you send long messages and large attachments. In simple word, it will enhance your text messaging and work similar to iMessage.
Currently, 65 carriers including AT&T, Verizon, T-Mobile, Reliance JIO, and a slew of secondary companies as well as 11 hardware manufacturers such as Samsung, Lenovo, and LG (but not Apple), and both Microsoft and Google has promised for the RCS.



Google has been backing the RCS to battle it out with iMessage, and Verizon have rolled out RCS to Pixel 3 and Pixel 3 XL to a limited number of users.
