Our verdict

Google Fi suits US readers who want a single rolling monthly bill, a plan that renews month to month, and roaming without a separate add-on. Unlimited Essentials costs $35 a month, the account runs as a mvno on T-Mobile, and the entry rate is $20 on the Flexible plan.

Pros and cons

Pros

  • Roaming is built into the plan across 200 countries, so a trip abroad does not mean buying a separate roaming add-on.
  • A sim only line is available, so you can keep your own handset and still get the newest mobile generation, an eSIM, wifi calling and hotspot sharing on the same plan.
  • A multi line discount is available, which suits a household or a couple sharing one account.
  • The plan contract is 1 month and billing is rolling, so the rate you sign at is the rate you renew at.
  • Support runs on email, chat and phone, so help is available by phone, chat, email, a help centre or the community.

Cons

  • Service is limited to US, so readers in Europe would need a different seller.
  • Google Fi is a mvno, so coverage follows T-Mobile rather than a network Google Fi runs itself.
  • The $20 entry price sits with the pay-per-gigabyte Flexible plan, while a flat unlimited allowance starts at $35.

Who it suits

  • Households in the US that want a single rolling bill across several lines, using the multi line discount.
  • People who travel regularly, since international service covers 200 countries and EU roaming is included.
  • Existing T-Mobile customers in the US, since the plan runs on T-Mobile.

Who should look elsewhere

  • Anyone who prefers to buy from a network rather than a mvno: GETESA, Lonestar Cell MTN and yesss! all sell as networks.
  • Readers outside the US, since Google Fi covers only US, and a network seller such as yesss! is the kind of listing to check instead.

What it does well

Google Fi packs the everyday extras into the base service. You can order a sim only line, which means a plan with no bundled handset tying up your choice of phone, and the newest mobile generation is part of the plan rather than an add-on. An eSIM is available, so a new phone or a second device does not have to wait for a plastic card to arrive. Wifi calling carries calls over a broadband connection when the signal is thin, and hotspot sharing hands data from your phone to a laptop or tablet. If you travel often, international service reaches 200 countries, and a multi line discount applies when you add lines to the same account.

Pricing

Two figures matter here. The entry rate is $20, and it belongs to the Flexible plan, which charges for the data you use rather than handing over a fixed allowance. Unlimited Essentials is the unlimited option at $35, with Unlimited Premium above it for anyone who wants more headroom. Billing is rolling and the plan contract is 1 month, so the figure you read today is the figure you renew at rather than an introductory rate that later changes. Month to month spending is easy to plan around, and a household whose data use turns out to be steady can move up from Flexible without changing how it pays.

Where it sits among rivals

Price is where the two readings of Google Fi differ. On entry price the brand sits at position 231 of 258, so some listings in this category start lower. On the unlimited price it ranks at position 124 of 173, a stronger showing. In short, the pay-per-gigabyte Flexible rate reads as expensive next to the cheapest sim only deals, while the unlimited plan holds a middling place rather than topping or trailing the field.

Who runs it

The service is run by Google North America Inc., which is based in the United States. Support is broad: you can reach the team on email, chat and phone. That mix means a quick chat for a small question, a call when something needs a real person, and a help centre or community board to search on your own. The legal name is worth keeping in mind if you ever need to quote a contract or query a bill, since the entity printed on your paperwork is the one to point to.

Frequently asked questions

How much does Google Fi cost to start with?+

The entry rate is $20 a month, and it belongs to the Flexible plan, which is charged for the data you use rather than a set allowance. If you would rather have unlimited data, Unlimited Essentials is priced at $35 a month, with Unlimited Premium sitting above it.

Is there a minimum contract or a lock-in period?+

The plan contract is 1 month, and billing is rolling, so there is no annual term to serve out. That makes it easy to try the plan for a short while, or to step away once the host network coverage proves right or wrong for you.

Which network will my phone actually use?+

Your phone runs on T-Mobile, because Google Fi is a mvno rather than a network operator in its own right. That matters if you are moving home or switching from another network, since coverage in your area comes from the host rather than from Google Fi.

Can I use Google Fi outside the US?+

The service is sold in US only, so you need a US line for it to work at home. Travelling is a different matter: international service covers 200 countries, and EU roaming is included in the plan price. Short trips abroad therefore need no extra buy.

Can I get a plan without a new phone?+

Yes. A sim only line is available, so the plan comes without a bundled handset and your own phone keeps working on the network. An eSIM is supported as well, which is handy if you travel or want a second device without waiting for a plastic card.

Is there a discount for more than one line?+

A multi line discount is available, so adding a second or third line to the same account costs less than running each plan on its own. It works well for a couple or a family, and every line stays on the same host network, T-Mobile.

How do I get help if something goes wrong?+

Support runs on email, chat and phone, so a quick question can go to chat or email and a more involved problem can go to a phone call. There is a help centre and a community board too, and the contract is with Google North America Inc., which is the name to quote on a billing query.

Does it handle weak signal and sharing data?+

Wifi calling is supported, so calls can carry over a broadband connection in places with thin mobile coverage. Hotspot sharing is available as well, letting a phone pass data to a laptop or tablet, and the newest mobile generation sits in the base plan rather than costing extra.
