Prior to Monday, if you wanted to use Google's Project Fi wireless service you had to request, and wait for, an invite.
Starting today, Google has lifted the invite system. Now, anyone in the US with a Gmail address can sign up for the service.
Before you get too excited, you'll need to know a couple of housekeeping items. You must live in a supported service area (Google will help you check during the sign up process), have a Gmail account, own or plan on purchasing a recent Nexus device (Nexus 6, Nexus 6P, Nexus 5X), and you must be at least 18 years old.
With that out of the way, you can visit Project Fi's sign up page fi.google.com/signup.
Sign in with your Gmail account and follow the prompts. The steps include entering a ZIP code, service address, picking a new phone number (or entering credentials to port an existing number), selecting a wireless plan, and ordering a Project Fi SIM card if you already have a Nexus device. If not, you can order a Nexus 5X for the limited time price of $199 or a Nexus 6P for $499.
Credit checks are only required if you finance your device purchase, and Project Fi is free of any contract commitments.
When your device or SIM arrives a few days later, the welcome kit will include instructions on activating your service.
