Google Fi Unlimited Essentials

Google Fi Unlimited Essentials supports up to five lines on one plan. The plan is built around unlimited talk, text, and data use within the United States.

The plan uses participating partner networks, including T-Mobile and Verizon according to the catalog description. Actual service depends on location, device compatibility, and network availability.

The plan includes international Wi-Fi calling benefits rather than treating all overseas cellular use as domestic service. Travelers should check the current Fi terms for data, calls, and roaming outside the United States.

It is designed for groups that need multiple lines, with a maximum of five lines. The main tradeoff is that the plan's unlimited domestic service does not mean every international feature is unlimited.
