Google Fi Wireless: How This Phone Plan Works and Whether It Is Worth It

Google Fi is a flexible phone plan that works on multiple networks and charges you only for the data you actually use each month.

At a Glance

Check if your phone is compatible

~19s

Go to fi.google.com and click "Check your phone" or look for the "Bring your phone" option. Enter your phone model to see if it is compatible. Most recent iPhones and Android phones work with Google Fi. If you need a new phone, Google Fi sells phones directly and offers occasional promotions for new customers.

Choose your plan

~32s

Google Fi offers a few plan options. "Simply Unlimited" is the standard choice for most people — a flat monthly rate with unlimited calls, texts, and data (speeds may slow after a certain amount of high-speed data is used). "Unlimited Plus" adds a higher-speed data cap, hotspot data, and a few other extras. Compare the current prices at fi.google.com/about/plans before signing up.

Quick Tip

Quick Tip: If you are the only person on the plan and you use a smartphone mostly for calls, texts, email, and occasional browsing — rather than streaming video — the standard Simply Unlimited plan is likely all you need.

Sign up with your Google account

~18s

Click "Get Started" on the Google Fi website. You will need a Google account (Gmail counts). Sign in and follow the steps to enter your billing address, choose whether to get a new phone number or transfer your existing number, and provide payment information. Google Fi charges monthly with no long-term contract.

Order your SIM card or eSIM

~22s

Google Fi will send you a physical SIM card by mail (free shipping, usually arrives in a few business days), or for compatible phones, you can activate an eSIM (a digital SIM that installs over the internet without a physical card). The SIM comes with instructions. When it arrives, insert it into your phone per the instructions, then download the Google Fi app to complete setup.

Transfer your phone number (optional)

~28s

If you want to keep your current phone number, choose "Transfer my number" during signup. You will need your account number and PIN from your old carrier — find these on your old carrier's website or by calling their customer service. The transfer usually completes within a few hours to one business day. Your old service cancels automatically once the transfer is complete.

Warning

Do not cancel your old phone plan before the number transfer is complete. Canceling first releases your number and may make it impossible to transfer.

Google Fi Wireless is a phone plan run by Google. It is what is known as a "virtual" carrier — Google does not own its own cell towers but instead uses the networks of T-Mobile and US Cellular to provide coverage. By combining multiple networks and switching between them automatically, Google Fi aims to keep you connected even in areas where a single carrier might have weak signal.

Google Fi offers two main types of plans. The "Simply Unlimited" and "Unlimited Plus" plans charge a flat monthly fee similar to traditional carriers. The older "Flexible" plan — which may still be available for existing customers — charges a base rate per month plus $10 for every gigabyte of data you actually use. If you use very little data in a month, the Flexible plan can end up being significantly cheaper than a flat-rate plan.

For a single person, current Simply Unlimited pricing starts around $65 per month for one line. Prices go down per line when you add more people to a group plan. Google Fi also includes international roaming in over 200 countries at no extra charge on most plans, which makes it attractive for travelers.

Google Fi works with most modern Android phones and iPhones. However, not all phone features work on every device when used on Fi — some advanced Fi features, like automatic network switching, only work on certain Android phones. iPhones work on Fi as a standard cellular connection.

The plan is managed entirely through the Google Fi app or at fi.google.com. There are no retail stores, though customer support is available by phone and chat.

Google Fi is worth considering for people who travel frequently, use modest amounts of data, or want a no-contract plan they can control easily online.
