When you sign up for Google Fi, you can use a Google Account you already have or create a new Google Account. You’ll be able to sign in to Gmail, Google+, YouTube, and other Google products with a single username and password.
Accounts that work with Google Fi
Most Google Accounts can be used with Google Fi, including:
- Google Accounts with "@gmail.com" email addresses.
- Some work or school accounts that use your own domain name (see below).
- Other Google Accounts, like "@yahoo.com" or "@hotmail.com" email addresses.
Google Accounts for work or school
If you have a work or school Google Account, also known as G Suite, your administrator has to turn on Google Fi service and Google Payments first. Otherwise, sign up with a new Google Account to use Google Fi.
