Carriers botched Google’s RCS messaging plans entirely, so the firm took over with its own strategy. Some carriers still provide the features, however, with some users of Google Messages working on their systems on Visible, Xfinity Mobile, and Simple Mobile reporting RCS.
First found by Android Police, some MVNO subscribers like Verizon’s Visible, Xfinity Mobile (running off Verizon), and Simple Mobile watch RCS go live.
As for the Visible of Verizon, it seems that RCS has been rolling out for a long time now. Some Redditors mentioned seeing the features on Pixel phones as far back as a month ago. A tipster also shared with AP that his newly switched Pixel to Visible’s service saw a prompt rapidly after setting up RCS features within the Google Messages app.
