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.
