Despite the prevalence of Internet-based instant messaging, like that used by Facebook, LINE, and iMessage, SMS remains the most basic way people communicate with their smartphones. Some tech pundits believe that it's time for it to give way to the next generation. One of those is Google, who has heavily invested on RCS or Rich Communication Services. Now, however, it isn't alone anymore. The GSM Association or GSMA, along with more than a dozen operators, have agreed to help push RCS. And adopt Google's RCS Android app as well.
