What is RCS and how it’s different from SMS? All about it

RCS Messaging Chat

RCS, the next generation messaging: Text messaging or SMS (Short Message Service) was very popular in the last two decades. But nowadays, most of us send text messages via messaging apps such as Whatsapp, Wechat or Facebook Messenger and iMessage. One of the reasons for using these apps is that SMS doesn’t support features like group-messaging, GIFs, photo sharing or animated stickers, which other messaging apps do. SMS also depends on your phone connection or network. This means, if you do not have signal, you’ll not be able to send or receive text messages. Also, the text is limited to 160 characters.

Despite all those limitations, text messaging is still popular, although the numbers have shrunk. Telecom carriers have realized the shortcomings of SMS and want to keep the message of text alive. That’s why they started thinking of a new messaging technology called Rich Communications Services (RCS), which would provide better features for next-generation messaging.

So what’s RCS messaging, and how does it work? Here you’re going to know all about it.
