It is an enriched messaging service that offers advantages over traditional SMS:

  • To see when people are writing
  • To confirm that the other person has received your message
  • To send messages using data or wifi (if wifi is enabled)
  • To offer open group support: a group that remains unchanged, regardless of any addition/removal
  • To share up to 100MB of multimedia content available to send high-quality images and videos
  • To send QR codes, dynamic files with online updates, and rebate coupons
  • To provide calendar integration
  • To share locations

With RCS you can interact with companies that agreed to communicate with you using your telephone number. For example, with RCS you can check in your flight, or check your bank balance.

To use these options, all conversation participants should have chat features enabled.

Customer devices need to have Google “Messages” app (for Android devices), or Samsung “Messages” app (for Samsung handsets).

What happens if RCS is unavailable?

Messages will be sent via SMS or MMS. Often times, fallback is the name given to the process of automatically changing to SMS/MMS when RCS is unavailable. One of the main advantages of RCS is that you don't need to worry about data connections or the person you communicate having RCS. The app is automatically adjusted and messages are always sent. The messaging app will specify if the message was sent as RCS or SMS/MMS.
