If you're an Android enthusiast and live in the United States, you likely know about Google Fi, but maybe its past limitations turned you away. Now that any unlocked phone can be used with it, you may be more interested in this MVNO than before. So, we're here to give you a high-level view of the prepaid carrier that comes directly from Google — what is it, how it works compared to other carriers, along with a few reasons why you'd want to try it.

What is Google Fi, and how does it work?

In the simplest of terms, Google Fi is a cell phone carrier operated by Google. Being a Mobile Virtual Network Operator (MVNO), it uses the network infrastructure of other big carrier(s) to provide service. Although those carriers used to be T-Mobile and US Mobile, Google Fi recently severed ties with US Mobile, thus making T-Mobile its sole official network infrastructure provider.

What are Google Fi's plans?

Google Fi keeps things simple with two unlimited plans and a flexible plan. With the 'Flexible' plan, you start with unlimited talk and text for $20 per month for one line. After that, you only get charged for the data you use at a rate of $10 per 1GB. Once you've used 6GB of data in a month, your data charge is capped at $60 for the rest of the month, but you continue to get data service.

This essentially means you can use as much data as you want for the month, without paying over $80 total ($20 base + $60 data). The only caveat here is that once you hit 15GB of total data usage, your data speeds are slowed to 256kbps. Alternatively, at the 15GB point, you can choose to start paying $10 per GB again for full-speed data access if needed.

If you know you will be using more than 15GB regularly, you can go with the 'Simply Unlimited' plan starting at $50 per month with one line. You don't pay per gig on this plan, but your speeds will be slowed at 35GB of usage. Unlike Fi's other plans, there are no international travel benefits and no data SIM option. You do, however, get 5GB of mobile hotspot data.

If you want everything, the 'Unlimited Plus' plan starts at $65 per month and comes with a massive 50GB of high-speed data, as well as the travel benefits of the Flexible plan. In addition, you get high-speed hotspot usage and the option for a free data SIM. This plan also comes with free calls to more than 50 countries, 100GB of cloud storage with Google One, and a one-year free subscription of YouTube Premium.

You can save some money on your plan if you have multiple lines, with the cost per line coming down with each additional line (up to a total four) on the unlimited plans and (up to a total five) the flexible plan. So, for example, you can have six lines total, but your cost per line will be the same as four. Additionally, you can add a data-only SIM for free, so you can share data with another device without needing to create a hotspot.

Are there Google Fi deals?

Absolutely! There are tons of great Google Fi deals worth checking out, with many more to be expected as we approach the holiday season. Most of these offers are only available to new customers who transfer their number to Google Fi, but they offer an easy way to save money on some of the newest and best Android phones without having to trade in an old device or sign up for some prohibitively expensive wireless plan. 

For example, if you purchase the Pixel 8 Pro and trade in an eligible device, you can get up to $700 back after 24 monthly credits. You can check out Google Fi's official store page to find out more about new offers.

If you're a new customer moving your number to Google Fi, and have one of the eligible smartphones from Apple, Samsung, or Google, you can get up to $700 back. That being said, you must get a full service plan (no data-only SIMs) and keep the service active for 24 months.

Does Google Fi support international usage?

Google Fi's Flexible and Unlimited Plus plans work internationally in more than 200 countries with no additional cost for data use or texting, which is one of its biggest differentiators from other carriers. You can call at a flat rate of $0.20/min to any number while on the cellular networks abroad or pay much lower rates when calling on Wi-Fi. You can also call back home to the U.S. on Wi-Fi for free. All the data used internationally is charged the same way at home, depending on your plan.

The only catch is that speeds can vary depending on the country you're in, which is to be expected. In our experience, we've found full LTE speeds in many countries in Europe and Asia, with the occasional hiccup as the phone switches between roaming partners.

What are the best phones for Google Fi?

If you have a phone that is 'Designed for Fi', then you will be able to access the entire Google Fi network. For the most part, 'Designed for Fi' phones include Google's Pixel series and a handful of Samsung Galaxy phones, including the latest S24 lineup. If your phone isn't on the 'Designed for Fi' list, you'll only be able to get service on T-Mobile's network, which will still work for many people. 5G is supported on both Designed for Fi and 'Compatible with Fi' phones, so you'll have access to T-Mobile's massive 5G coverage if your phone supports T-Mobile's 5G bands.

You get access to T-Mobile's vast 5G network, Wi-Fi calling, international service, and a lot more.

In addition to the traditional mobile networks, Google Fi also leans heavily on Wi-Fi whenever possible, whether you're around a known network or not. As you move around, your phone will use the "Wi-Fi assistant" to constantly search for and connect to open Wi-Fi networks, using a database of known good networks that can provide a solid connection. Whenever your phone connects to Wi-Fi, the connection is routed through a VPN for your safety — and you won't notice anything different in the phone experience, except that you will no longer be paying for mobile data.

Calls and texts work on Wi-Fi just as they do when you're on mobile data, and you can continue your phone call as your phone switches between networks.

When you use Google Fi, you also get some of the same features that have made Google Voice popular over the years. You can forward phone calls to your Fi number to any phone you want, as well as view voicemail, make calls, and send texts with that number from any device using Google Messages.

Which phones are Designed for Fi?

Google's approved phones give the best experience, but Google Fi still works well with a wide range of unlocked phones.

You get a truly first-class experience with Google Fi on Google's Pixel series of phones. These phones have an eSIM inside that's pre-programmed for Fi, and you can set up an account and connect to its network without putting in a SIM card.

Then there are other 'Designed for Fi' phones that you can buy and use to get the same experience, like the Samsung Galaxy S24 series and Samsung Galaxy A54.

Even if they aren't technically Designed for Fi, all of the best Android phones should work with Google Fi's full network.

Which phones are compatible with Fi?

Google Fi now works with any unlocked phone — with some limitations. Unlocked phones can't take advantage of Fi's network switching, so you'll be using T-Mobile's network primarily, and you don't get Fi's always-on VPN option. But you do get the same great international roaming, plus all of the other features like the great Fi app and simple billing. Yes, that unlocked support also includes iPhones, which is a big advantage with Google Fi. It even supports iMessage using your Fi number.

One thing to keep in mind is that T-Mobile has been integrating Sprint's towers into its network, so even phones that weren't designed for Fi can access the majority of Google Fi's coverage.

Android phones with 5G support will also get access to 5G on Google Fi. But iPhones, even the newest iPhone 15 series, don't support features like network switching and end-to-end encrypted calls.

Google Fi now supports 5G on its Designed for Fi phones as well as Compatible with Fi phones that support T-Mobile's 5G network. This means your phone will need to support bands n71 and n41 for the best 5G coverage on T-Mobile's network.

Designed for Fi 5G phones include the latest Google Pixels, as well as many unlocked Samsung models. In addition, Samsung's Galaxy S23and S24 series, Galaxy Z Flip 5, and Z Fold 5 phones will work with Google Fi's full network. This includes access to its full array of LTE as well on all networks.

How to finance a phone with Google Fi

So long as you qualify (up to Google, based on a credit check), you can purchase a new phone and pay for it in monthly installments. There's no down payment needed and no interest; the cost of the phone of your choice is spread out over 24 months.

You can pay off the balance at any time, but if you decide to leave Google Fi, you'll have to pay out the total cost of the phone then and there. You have 30 days to activate Google Fi service from when you buy your phone. If your Google Fi service isn't active within 30 days, Google will charge you the full amount for the phone.

What if I need Google Fi support?

What happens if something goes wrong with my Google Fi phone?

Talking to tech support is one of our least favorite activities and being in a store that will just try to sell you an upgrade or accessories doesn't make it any more fun. With Google Fi, if you need help, your best bet is the app. And this just might be the best carrier app you've ever used. You can download the Google Fi app for Android or iOS and get access to 24/7 phone, chat, or email support.

If your phone is having problems or you just want to chat on a device with a proper keyboard, you can freely access Google Fi's support page for the same options.

I just need to see my Google Fi usage and billing

The same app and sites for support work great for showing you your real-time usage and how much it will cost you. The widget on Android keeps you constantly informed on how much data you are using. You will have to open the app on iOS to see this information, but a data warning can be set to send a notification when your data usage gets high. With these tools, your bill should never be a surprise.

How do I cancel Google Fi service?

It's very simple. All you have to do is head to the Google Fi website or open up the Fi app:

  1. Click or tap on the Account tab.
  2. Click or tap on Manage Plan option under the Home section.
  3. Click Leave Google Fi.
  4. Follow the instructions.

If you're switching to another carrier and want to keep your number, you should set up your new plan first to successfully port your number over. When closing account with Google Fi, you get your port-out number and PIN.

Can I use my Google Fi phone with another carrier?

Provided it works with that particular carrier (chances are it will), yup. Google clearly states that your phone is not locked to Google Fi service.

Switching to Google Fi

If you're OK with the inherent hassle of switching carriers and porting your phone number, you don't have many other hurdles to jump over now that Google Fi is open to just about any unlocked phone. You can sign up for Google Fi online in minutes, and you can either buy a phone at the same time (and avail some nice discounts and incentives), or Google will send you a SIM card to put in your existing phone. Or, if you already have a Pixel, you can get up and running in minutes with the eSIM.

T-Mobile bought Sprint. Does that affect Google Fi?

On April 1, 2020, T-Mobile completed its purchase of Sprint, bringing the two networks under the ownership of T-Mobile. T-Mobile has unified the two networks and has been moving the remaining Sprint customers to the T-Mobile network. As a result, Google Fi customers likely won't see a significant change in service quality, although it is possible that some rural customers may see some changes, hopefully positive.

Still, compatibility with T-Mobile's infrastructure looks likely into the future, as even unlocked phones that support T-Mobile's 5G will be able to use 5G with Google Fi. T-Mobile has stated that it will continue to support MVNOs, which isn't likely to change any time soon.

T-Mobile has also shut down its own as well as Sprint's 3G networks to free up space for 5G, and most users will never notice a difference in coverage. The vast majority of phones sold in the last several years all support LTE and will continue to work fine on Google Fi.

Google Fi: Should you buy?

There are a lot of cool features that make Google Fi a good choice, like dramatically simplified billing, Bill Protection to cap your charges every month, seamless international data and calling, and improved network coverage through the use of carrier infrastructure and Wi-Fi networks. Of course, each one will have a different amount of draw for different people, but that's a pretty compelling package.

Google Fi's pricing isn't dramatically lower than other carriers out there, and whether it makes a good choice financially for you depends on your data usage and which features you want. Therefore, we encourage you to do your pricing research before choosing which carrier is the best.
