Terms and definitions in messaging

Multichannel messaging service is based on a variety of telecommunication and Internet technologies. In the description of services, we often use abbreviations that may not always be known to you. Here we have compiled a glossary of terms and definitions used in the industry.

RCS

The GSM Association’s Rich Communication Services (RCS) messaging standard was originally mooted in 2007. It promised an MMS experience for business-to-consumer messaging. But SMS enterprise messaging has prevailed instead.

RCS received a reboot when Google announced plans to provide RCS messaging as a native function of Android Messages. Now it's a growing number of carriers and OEMs agreeing to make it their default-messaging app, supporting the RCS standard.
