An interesting rumor has come out of Spanish site Xataka Android. Apparently, Google-branded SIM cards have been spotted and tested on the Nexus S. The rumor suggests Google will look to either Pepephone or Simyo to help them become an actual carrier. On the photo below, you can see the carrier branding is “Google_Es”.
This is interesting, though methods do exist that allow users to change carrier branding themselves. We doubt Google Voice will translate into a Google-run carrier business, but the possibility does remain. For the time being, it’s still just a companion service to the cellular service you already have. [Thanks Roberto!]
