Google's become a carrier of sorts in the US earlier this year, through its Project Fi venture. Since Fi operates on both T-Mobile and Sprint's networks, there are some hardware and software tweaks needed for a device to work with this carrier, which is why up until now the Motorola Nexus 6 has been the only supported phone.
Interestingly, it's now been revealed that if you are a Project Fi customer and have purchased your Nexus 6 from the carrier, you can benefit from a pretty neat perk.
Namely, if your Nexus 6 becomes damaged for whatever reason, Project Fi will replace it for you for a fee of just $100, no questions asked. As you may have expected, there are caveats here. First and foremost, this is all a one-time thing. So you can't keep replacing phones after the first one.
Second, your replacement request has to happen within one year of the moment you bought your Nexus 6 from Project Fi. After that, you won't be able to take advantage of this offer.
