It’s a protocol that originated in 2008 as a potential replacement forSMS messaging.
Since then, RCS has continued to make inroads.
It’s an upgrade to the outdatedGlobal System for Mobile Communications(GSM) standard, which SMS uses.
This relative simplicity is part of why SMS continues to be so pervasive despite being a decades-old technology.
Unlike SMS, which runs over a voice-only cellular connection, RCS requires a mobile data connection.
One of the main advantages of RCS is that its underlying technology allows for increased integration with smartphones.
Along with supporting rich content like high-res images and video, RCS provides read/delivery receipts and typing indicators.
Theres a common misconception that RCS offers improved security over SMS, but this isnt necessarily true.
Like SMS, RCS messages are unencrypted, leaving them open to interception.
However, Google Messages offers end-to-end encryption, which effectively makes RCS an encrypted protocol.
Encryption is on by default in Google Messages.
The other main benefit of RCS is more theoretical at this stage.
However, universal support is necessary to make a text-app-free gadget a reality.
How Do I Use RCS?
Similarly to SMS, you dont need to download any specific app to start using RCS.
The caveat is that your carrier needs to support it, and you should probably use Google Messages.
Assuming the above criteria is met, your regular text messages should be sent using RCS.
If not, theyll receive your messages as SMS.
