Found this startup advertising its mobile plan. Now a Pixel 8 Pro purchase will get you a free 12-months unlimited mobile plan. It seems to be good deal for the phone itself already.
Regarding the mobile plan quality, some reddit posts mention the network provider is T-mobile and people are satisfied with what they are getting so far. But again, it’s a startup, of course it’s going to start strong, but who knows what will happen in a year…
