Google Fi (formerly Project Fi) is one of the carriers you can consider while looking to cut down your monthly phone bill. You can also enjoy prioritized data and extended network coverage. But that’s assuming you have the right phones compatible with Google Fi host carriers

 Of course, most of the LTE and 5G devices in the market today should work well on Fi service. The company no longer limits its users to Nexus and Pixel phones as they used to. So, you could even use your cheap Motorola without any issue.

Regardless, there are a few crucial factors if you want to make the most with your phone on Google Fi. And in this guide, I’ve summed everything you should know as of today, including the latest improvements on Apple’s iPhone support.

What’s Phones Work Best with Google Fi Service?

As I’ve just said, most LTE and 5G phones are compatible with Google Fi. The network provider has T-Mobile as one of its underlying networks. And if there’s one thing we can agree on, AT&T and T-Mobile, which are GSM carriers, have the most lenient compatibility rules.

Sadly, however, Fi is yet to fully embrace Apple as everyone else. So, my four favorite phones compatible with the network are currently Android, including:

6 Things to Consider Before Bringing a Phone to Google Fi

Before you can bring your phone to Google Fi, you should know:

  1. Google Fi as an MVNO

Yes, indeed, Google Fi is a mobile virtual network operator (or MVNO) on T-Mobile and US Cellular networks.

But in the Google Fi vs AT&T review, we mentioned your phone will be switching to the strongest signal in your location. Thus, won’t need separate lines or phones like Red Pocket and Consumer Cellular.

Also, this means you can make the most on Google Fi with a phone compatible with T-Mobile and US Cellular frequency bands. Then again, the two host networks have many LTE and 5G frequency bands alike. See below.

Carrier NetworkPrimary 4G LTE BandsSecondary 4G LTE Bands5G Low-Band Bands5G mmWave Bands
T-Mobile4, 12, & 712, 5, & 66n71n41, n258, n258, n260, & n261
US Cellular5 & 122, 4, 46, 66, & 71n71n260 & n261

Recommendation: Your Phone will work best in Google Fi if it has at least bands 5, 12, 4, & 71 for LTE coverage. Then, bands n71 and n260/ n261 for 5g connectivity.

  • Has Limited Apple Support

Technically, we’ve got many carriers that work better on Apple devices than with Androids. On the list of the phones compatible with Visible and Spectrum, you’ll even notice only iPhones qualify for the smartwatch add-on plan.

On its end, though, Google Fi has prioritized android devices over iOS on its service. A good example here’s the 5G access and WiFi calling, which is unavailable for iPhone users.

There are speculations the two features might be available sometime soon- perhaps from the continued criticisms from the users. But before that happens, you might want to have an Android device to make the most of your Fi service.

Phones Compatible with Google Fi
  • You can Activate eSIM

Yes, Google Fi does support eSIM activation. Thus, you can have a phone with the feature to take advantage of instant activation or dual-SIM mode.

  • Supports WiFi Calling

Yet again, Google Fi does support WiFi calling if outside the coverage areas and doesn’t want to pay expensive roaming charges. Only remember no WiFi calling support for Apple devices at this time.

  • Gets Prioritized Data

Similar to MVNOs like Verizon’s Xfinity and Spectrum Mobile, Google Fi usually gets prioritized data from T-Mobile. Thus, you’ll have a more usable phone than other traffics during congestion on the host towers.

  • Sells Unlocked Phones

Usually, Google Fi can lock phones purchased on an installment agreement to T-Mobile if the owner is late on payments.

But for users who purchase upfront or pay the monthly installment on time, Fi will have the phones fully unlocked. Thus, you should be able to use with SIM card from other compatible carriers without issues.

A Summary of the Best Phones compatible with Google Fi

Before all else, Google Fi is compatible with three different types of phones, including:

  • Factory Unlocked: these are the unlocked cell phones that come directly from the manufacturer as such.
  • Carrier Unlocked: just as the name, these are the phones that were previously locked to another carrier but now are fully unlocked.
  • T-Mobile Branded: Sure, you can use a T-Mobile phone on Google Fi even before unlocking.

Even with either of the three types of phones above, there’s no guarantee it’ll work on Google Fi. And the explanation for that comes down to the network technology: i.e. the LTE/ 5G frequency bands I’ve mentioned earlier.

Anyway, some of the best phone brands that are compatible with Google Fi on both T-Mobile and US Cellular towers include:

Does Google Fi work better with Google phones?

Indeed, Google Fi works best with Google Pixel phones as they come preinstalled with the required network technology. But you could use your service on Samsung, OnePlus, and most of the other Android devices with the necessary network bands.

What phone lines does Google Fi use?

Google Fi currently uses T-Mobile and US Cellular phone towers since Sprint service is no more. If you have the right phone, your line will even be able to automatically switch to the strongest signal of the two networks.

Are Verizon phones compatible with Google Fi?

Yes, of course, unlocked Verizon phones are compatible with Google Fi if the primary network bands are available. A perfect example would be the Verizon-unlocked Google Pixel 3a smartphone, which has LTE bands 2, 4, 5, 12, 25, and 66.

Do all Android phones work with Google Fi?

Similar to MetroPCS, many but not all Android phones work with Google Fi. As was mentioned, a phone must have the necessary LTE/ 5G bands to tap into the signal frequency of T-Mobile/ US Cellular, carrier networks of Fi.

Beware the International Phones

If we decided to list down all the phones compatible with Google Fi, we’ll be here the whole day. Its major carrier network, T-Mobile, operates on network frequencies conversant with many phone manufacturers.

But even then, it’s not all phones will have the technology your Fi service needs to operate. And for that, I’d recommend paying attention to the model numbers while shopping from a third-party retailer like Amazon or Walmart.

Also, refrain from buying phones listed as “international” versions. In many cases, these devices have the secondary bands of US carriers. Then, sadly, major carriers have started to blacklist them such that you can’t use your SIM.
