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.
Most Google Accounts can be used with Google Fi. These include:
- Google Accounts with "@gmail.com" email addresses.
- Accounts that use your own domain name, like work or school accounts.
- 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 Google Workspace, your administrator has to first turn on Google Fi service and Google Payments. Otherwise, to use Google Fi, sign up with a new Google Account.
