Google’s Project Fi program currently supports pretty much all the Pixel devices as well as some older Nexus handsets. As far as non-Pixel and non-Nexus devices are concerned, there are a handful that are supported, but that could change soon as it has been reported that support for other handsets could be introduced soon.
This comes in the form of a report from BGR (which has since been taken down; via Droid-Life) suggesting that Project Fi could soon start supporting other handsets including those by Samsung, OnePlus, and even Apple’s iPhones. Right now the handsets that are already supported include those from LG and Motorola.
That being said, the report notes that apparently while these new phones will be supported, they might not get the full Project Fi experience, which suggests that automatic network switching between T-Mobile and Sprint might not be available for handsets not designed for Project Fi. Details about the program are a bit unclear at this point in time since the post has been pulled and Google has yet to officially announce anything.
Either way we’ll keep our eyes peeled for more information, which hopefully will be available soon as the support for the additional devices is expected to go live today.
