The Reddit thread actually doesn't really understand what is going on. Google has NOT released an RCS capable version of the Google messaging app that uses the T-Mobile network. Google does have the capability of building an over-the-top version but it won't be compatible with the T-Mobile network.
DIGITS however does use RCS natively and anyone using the DIGITS applications or any modern T-Mobile sourced phone (other than iPhone) are also already using RCS.
There's a lot of confusion out there, all that Google has really done is renamed the Jibe client they purchased to be Google RCS for Sprint and providing it to other carriers who don't have a native RCS implementation. The standards bodies have agreed on a new profile for RCS to better allow interoperability, but that will still require a lot of time, effort and work for companies to build out the pairing and interchange capabilities between the different networks. Many people believe this will just *poof* magically happen over night.
So all said, it will happen eventually, but it will still take a bunch of time for it to be ubiquitous across all carriers and networks.
Thank you. I found it very suspicious that only the poster could use it and lots of other people couldn't or didn't see any changes. Glad I posted here and you could clear this up.
