Frequently asked questions

Does Google Fi and T-Mobile use the same network?

Yes — both Google Fi and T-Mobile ride the T-Mobile network. Coverage is identical between the two; the differences come down to plan structure, pricing, and where each one sits in the deprioritization queue. Postpaid traffic on the underlying carrier still gets first priority.

Which is cheaper, Google Fi or T-Mobile?

The cheapest Google Fi plan we have on file is $20.00/month; the cheapest T-Mobile plan is $75.00/month. By starting price, Google Fi is cheaper. Compare the actual plans side by side above for data, hotspot, and feature differences — the cheapest plan isn't always the best value.

Is Google Fi better than T-Mobile?

It depends on your usage. Google Fi and T-Mobile have different price points, plan structures, and underlying network (both on T-Mobile). Use the comparison table above to evaluate plans head-to-head, or enter your ZIP in the finder to see which network has stronger coverage at your specific address.

Can I switch from Google Fi to T-Mobile and keep my number?

Yes. Number portability is required by FCC rules. Get a port-out PIN from Google Fi, sign up at T-Mobile with "transfer my existing number," and provide your account number, port PIN, and billing ZIP. Most ports complete in 15 minutes to 4 hours. See our switching guide for the full walkthrough.

Whose coverage is better, Google Fi or T-Mobile?

Google Fi and T-Mobile have identical raw coverage since they ride the same T-Mobile network. The practical difference appears at congested towers, where the underlying carrier's postpaid customers (and carrier-owned MVNOs like Visible/Cricket/Metro) get prioritized over third-party MVNO traffic.
