Google Fi: What Is It and Is It Worth the Money?

Mobile Network

If you’re a Google or Android aficionado, then you must have heard about Google Fi. However, there is more to this unique mobile carrier that you might not know of. Since Google Fi’s popularity has slowly been attracting users with unlocked phones, there is a lot to get hooked on this innovative product from Google. While we figured you might be interested to know how Google Fi works, we compared and highlighted some of the reasons why Google Fi deserves your attention now. 


What Is Google Fi?

In 2015, tech giant Google developed Project Fi. It is a mobile virtual network provider that is compatible with Nexus and Google Pixel mobile phones as well as the Motorola Moto X4. After three years, the company publicized the project and had been acquired directly under Google’s branding with its name modified to Google Fi. But that’s not just it – Google Fi also supports most Android devices and works on iOS devices such as iPhones.

Google Fi delivers texting, voice, and data service for a flat rate and highlights a robust mobile network that reaches the majority of the places bordering the United States. It is considered one of the few wireless mobile carriers in the country to refund its users for the data they haven’t used for the month. For example, if you consumed 7.5 GB worth of data in a month on a 10 GB subscription plan, then you will be credited for the remaining 2.5 GB of unused data. Google Fi also now provides you with an unlimited data plan, which doesn’t have the usual pay-as-you-go scheme but might be a lot better for users who tend to use a lot of data.

It’s easy to register for a Google Fi subscription. Not only can you register through the Google Fi website but you can also visit any Best Buy stores and purchase a SIM card off the shelf. The drawback, nonetheless, is that you’ll need to pay $10 for the Best Buy SIM cards. When you register online, Google will deliver the SIM card to you without a fee. You can switch your mobile number from the current service you use instead of using a new one.

From a high-level perspective, Google Fi is a mobile carrier powered by Google itself. What makes it unique is that Google Fi relies on a combination of three major mobile phone network providers in the US, namely, Sprint, T-Mobile, and U.S. Cellular for data coverage. As a result, if you have a compatible mobile phone, it can intelligently switch between the three service providers depending on the signal strength and network congestion. 


What Are the Google Fi Plans?

Google Fi has two subscription plans implemented by Google, namely, “Flexible” and “Unlimited.” Google Fi’s all-new Unlimited plan is considered a better plan for individuals who consume a lot of data every month and don’t have to worry all the time about their data usage. However, the Flexible plan is the traditional plan of Google Fi, letting users pay for the amount of data they have consumed for the entire month.

Google Fi Flexible Plan Pricing

If you are an average data user or prefer the idea of only paying for the amount of data that you consume, then Google Fi’s Flexible plan is an excellent option for you. Here is the current pricing as of this writing for Google Fi’s Flexible plan:

Individuals/Users Line Fee/Cost Data Fee/Cost Total
1 $20 $10/GB Per User $20/Month + Data
2 $18 $10/GB Per User $35/Month + Data
3 $17 $10/GB Per User $50/Month + Data
4 $17 $10/GB Per User $65/Month + Data
5 $16 $10/GB Per User $80/Month + Data
6 $16 $10/GB Per User $95/Month + Data


Despite the fact that Google Fi’s Flexible plan is considered a bit pricey, it is integrated with a lot of excellent perks. Subscription starts at a flat rate of $20/month for unlimited texting and calling and $10 for 1 GB of data; however, money for data that isn’t consumed is credited back to the subscriber’s account. On the contrary, excess data will be charged $10/GB used. Google Fi also doesn’t charge an amount on mobile hotspots; thus, data consumed while tethering is deducted from a person’s monthly allotment.

In terms of plan and pricing, this mobile carrier’s Flexible plan isn’t entirely the most affordable prepaid phone plan available. For instance, Republic Wireless offers a maximum of 5 GB of 4G LTE, texting, and calling service for only $40/month – it is $30/month more affordable than the Flexible plan while FreedomPop’s 5 GB plan starts at $35 monthly. Also, Cricket Wireless charges $55 per month for unlimited data, text, and talk bundle.


Google Fi Flexible Plan Benefits

Another noteworthy benefit of Google Fi’s Flexible plan is the Bill Protection, which provides you with unlimited data for $80 if you have a single subscription. This is due to the fact that Google no longer charges over 6 GB of data. For example, if you consume 10 GB worth of data, you will still be paying only for the consumed 6 GB. The only drawback is that Google claims that users might experience slower speeds when they’ve already used more than 15 GB of data. Google Fi’s Bill Protection is different depending on the levels of group plans.

You may verify more information about Bill Protection through Google Fi’s website. As mentioned, it is important to consider that the 6 GB cap is only applicable to a one-person subscription. The cap increases to 10 GB for two subscribers, 12 GB for three subscribers, and 14 GB for four users. Lastly, five and six-user subscriptions are capped at 16 GB and 18 GB correspondingly.

Group Plans of Google Fi also allow you to add other individuals to your subscription for a $15 additional fee monthly. Group Plans enable you, as the plan manager, to pause a member’s data consumption, add monthly allowances, configure data notifications, and view data usage per member. There is also an all-new feature integrated into the Group Plans called Group Repay. This feature automatically calculates per member’s shares of the monthly fee and enables payment in fixed amounts based on a person’s total data consumption or only for data consumption above the expected allotment.



Google Fi is compatible with more devices; however, you’re better off sticking to a mobile phone that is part of Google’s approved devices list.

Google Fi’s Flexible plan is a suitable option for individuals who don’t consume a lot of data but might use a lot of it along the way. If you regularly consume more than 6 GB of data, then the Unlimited plan might be the perfect alternative for you.


  • Integrated with Bill Protection
  • No additional fees for tethering service
  • Excellent speed on international data at 0 fees
  • Savings for lite data consumers
  • Excellent coverage in rural areas


  • Expensive

Google Fi Unlimited Plan Pricing

It has become part of mobile carriers that offer unlimited data subscriptions, which is good news for individuals who consume a huge amount of data every month. Here is the current pricing as of this writing for Google Fi’s Unlimited plan:

Individuals/Users Line Fee/Cost Total
1 $70 $70
2 $60 x 2 $120
3 $50 x 3 $150
4 $45 x 4 $180
5 $45 x 5 $225
6 $45 x 6 $270


Google Fi’s Unlimited plan provides you with unlimited data; however, unlike any traditional unlimited data plans available nowadays, there is a unique and impressive feature. For instance, you will have high-speed data for 22 GB but if you’ve consumed all your data allowance, your speed may be regulated. Not only that, but Google also claims that video streaming is at 480p. You also have the option to pay $10/GB of excess data.

Also, similar to other Google Fi plans, it comes with some great benefits – especially for individuals who travel a lot internationally. The Unlimited plan delivers free texting service and data while traveling. In summary, you can still use your data as it is while you’re in the country. It supports more than 200 destinations so you are mostly covered wherever you are around the world. However, there’s an international rate for calling, which is significant to take note of.

With Google Fi’s Unlimited plan, the company will also bundle 100 GB worth of storage for each user on your subscription. It may not be much of saving; however, it comes in handy for users who already registered with Google’s storage.



Google Fi’s Unlimited plan is cheaper compared to other carriers’ unlimited plan offers. It is perfect for individuals who don’t want to worry about their data usage per month.


  • Impressive international coverage
  • Inexpensive
  • Excellent coverage


  • 100%-compatible mobile phones are limited

If you have a mobile phone that is compatible with Google Fi, you will completely enjoy all the benefits and services of the Google Fi network. This mostly includes the Pixel series from Google itself and older Nexus mobile phones. When you activate Google Fi on your mobile phone with the app, it will be able to seamlessly switch from one mobile network (Sprint, T-Mobile, and U.S. Cellular) to the other, depending on the best coverage without user input. That said, it’s like having one large collection of mobile networks plus Wi-Fi in one SIM card.

If your mobile phones aren’t compatible with Google Fi, you can still receive its service through T-Mobile’s network. As with any other mobile carrier, you should verify Google Fi’s complete coverage before purchasing its service.

Aside from the specified mobile networks, Wi-Fi is also a crucial element when using Google Fi. If you’re moving around, your cellular phone will utilize the “Wi-Fi Assistant” to consistently search for and connect to available Wi-Fi connections utilizing a repository of known good networks that offers a robust connection. Every time you connect your phone to a Wi-Fi network, the connection passes through a VPN to keep your connection secure. It does not create any disruption to your experience; even better, you get to save on mobile data charges.

Texting and calling services work on Wi-Fi similarly when you’re connected to mobile data and you can continue your calls as your mobile switches between mobile networks.


How to Register for a Google Fi Account?

If you ever used the widely sought-after Google Voice, then you can take advantage of the same functionalities if you register for your own Google Fi account. You can forward calls to your Google Fi number and any mobile you prefer. You can also send text messages, make phone calls, and view voicemails with that specific number from any device using the Hangouts website and app.
