Google’s personal carrier service, Project Fi, is finally ditching invites for everyone in the US. This move is coming ten months after the launch of the service. Fi is a Google smartphone carrier service that aims to restructure smartphone plans. It hopes to achieve this by creating its own mobile virtual network operator, and combining Sprint and T-Mobile coverage maps, which apparently gives Fi the best possible coverage.

Rather than build its own network, Google opted to rely on Wi-Fi hotspots and cellular service from T-Mobile and Sprint for Project Fi connectivity. Phones connect to the strongest signal in a given area, and move between them seamlessly. You can shut off Wi-Fi like any other phone, though Google recommends keeping it on.

Instead of paying a flat fee every month and using or losing what you have, Project Fi only charges customers for what they use at a competitive price of $10 per gigabyte. Fi also comes with a built-in customer service, which may be a plus for some.

To make this offer more attractive, Google has discounted the Nexus 5x to $199, for those who choose to sign up. The LG handset sports an HD LCD display, USB-C port, fingerprint sensor, and 12.3-megapixel Sony camera sensor.
