To send messages over an internet connection, the recipient must also have RCS Chat/Chat features enabled on their device. When sending a message to a contact who has the feature enabled, the message box will display ‘RCS message,’ otherwise, it will show ‘Text message.’ With RCS Chat, users can send high-quality pictures, GIFs, files, contacts, and even their location. Also, messages sent via RCS chat show when it has been delivered and if it has been read by the recipient. In addition, users can turn on typing indicators under the RCS chats settings menu.
Even after RCS messages are activated, users can continue to send SMS or MMS messages to the same contact. Google provides users with the option to choose if a message should be automatically resent as a text (SMS/MMS) if it fails to send via RCS chat. It is also easy to know if a message was sent via SMS/MMS or RCS chat.
Messages sent using the former are light blue while RCS messages are dark blue. Users also don’t have to worry about security as RCS messages are end-to-end encrypted and can’t be read by third-parties or even Google. A lock will be visible on the send button when encryption is active. There will also be a lock on the time stamps of sent messages. However, SMS/MMS messages sent via the Google Messages app are not encrypted.
