The company plans to become a mobile virtual network operator, or MVNO, which means that it would buy spectrum from a big carrier like AT&T and then re-package the service and sell it to users under Google's brand.
Now, blog Android Police has unearthed some information about how exactly the company could execute that plan.
Android Police discovered an unreleased Google app called Tycho within firmware for the Nexus 6 that was uploaded to a website MotoFirmware.center. The firmware likely ended up there by accident, since it was taken down soon after. Android Police says it was part of an internal build that was meant to be distributed to testers only.
