Rich Communication Service (RCS) is the next generation of wireless messaging. Instead of using a carrier’s cellular connection as SMS/Text does, RCS relies on a data connection or Wi-Fi. As a result, each message can contain as many as 8,000 characters compared to the 160 that each text message is capped at. In addition, larger and higher-quality video files can be shared using RCS, and users get a receipt when the recipient of a message has read it. Larger group messaging can take place with RCS as up to 100 participants can chat together at the same time.
