RCS is a big advancement over standard SMS texting. It lets you use read receipts, see when someone else is typing, text over Wi-Fi and send higher-resolution pictures and video. These features have been available in Apple's iMessages for quite some time. In the past few months Google has been on certain wireless carriers. Now the tech is coming to the Google Fi network.
Google says it's rolling out the RCS update starting Jan. 14 and "in the coming weeks."
Google says RCS will also work with a larger list of Fi-compatible phones, but you'll have to download the Messages app and set it as your default messaging app. From there you'll be able to turn on RCS.
