What You Need to Know


Launched in 2015, Google's Project Fi takes a Wi-Fi first approach to mobile service. When a supported Wi-Fi hotspot is available, your phone will route calls, texts and data through an encrypted connection instead of using a mobile connection. 

When away from Wi-Fi service is provided using the Sprint, U.S. Cellular and T-Mobile networks. This means coast-to-coast coverage with fewer dead spots.

Plans are monthly only. Unlimited talk and text starts at $20 per month. Add data for only $10 per GB. You can also share your data with additional lines and devices for $15 per month.

Phone support for Project Fi is limited. If you need a device, no-interest financing is available. Bring your own phone support is currently limited to a handful of device. However, they offer trade-in credit for gently-used phones to help with purchasing a new one.

What’s Good?

  • No-interest phone financing
  • No contracts
  • No early termination fees
  • Refunds on unused data
  • Shared data plans available
  • Free data-only SIMs for tablets with active service
  • All plans include unlimited talk and text
  • Free data roaming in 135+ countries

What’s Bad?

  • Limited phone support

Notable Features

Credits for Unused Data: If you use less data that is budgeted in your monthly plan, you'll receive a credit of approximately $0.01 per MB on your next bill.

Shared Data Plans: Add up to 5 lines to your account to share data across devices and save on monthly plan fees.

Seamless, Secure Wi-Fi Coverage: Project Fi uses open Wi-Fi connections near you instead of mobile network connections whenever possible. All connections use an encrypted VPN to ensure you're secure. If you leave range of Wi-Fi while on a call, you'll automatically switch to mobile without dropping your call.

Faster, Consistent Speeds: Project Fi checks connection speeds regularly to ensure you're always on the fastest possible connection without having to switch settings yourself.

How's the Network Coverage and Speed?

Predicting coverage and speed for Project Fi is tricky. Since it uses Wi-Fi when possible, your experience will depend on the quality of Wi-Fi networks in your area.

However, even on mobile networks, your experience will likely vary by location. This is because Project Fi uses three different networks to provide mobile access.

To check the speeds and coverage of the different networks used, check the carrier summaries below:

You can check coverage in your area across the various networks using Project Fi's coverage map.

Do They Charge Roaming Fees?

For domestic coverage, there is no need to worry about roaming. 

If you are travelling outside the US, roaming fees will depend on your destination. 

Project Fi offers flat-rate roaming in more than 135 countries around the world.

Data, text and Wi-Fi calling to US numbers are billed at the same rates as domestic usage in these countries. Calls to international numbers are subject to international calling rates. Calls over a mobile network are $0.20 per minute.

You can find a full breakdown on their International Call Rates page.

Outside of the 135+ countries supported, mobile data is not available. However, Wi-Fi text and calling will still work.

What About Long Distance Fees?

Calls to landlines and mobiles in the US and Canada are included with your plan.

However, calling other countries will result in a per-minute fee. Fortunately, Project Fi offers some of the best international rates available.

Per-minute rates vary by country starting at just $0.01 per minute.

You can find more about specific calling rates and options on the International Calling Rates page.

Does Project Fi Offer Wi-Fi Calling?

Yes. In fact, your phone will default to Wi-Fi calling whenever possible. It will also seamlessly transition between mobile network and Wi-Fi calling when needed.

How About Voice over LTE (VoLTE)?

Possibly.

VoLTE support is slowly rolling out to Project Fi subscribers with T-Mobile network coverage.

At the time of writing, neither Sprint or U.S. Cellular support VoLTE, so subscribers in those coverage zones will not have access to the feature.

You can read more about the Project Fi VoLTE rollout on their subreddit.

Can I Tether My Phone?

Yes. Tethering or using your phone as a mobile hotspot is included at no additional charge. However, any data used by devices connected through tethering counts against your monthly data allotment. 

When tethering, track your data usage closely. Laptops, gaming consoles and other non-mobile electronics often consume more data than your phone or tablet will.

Can I Rollover Unused Data?

No. However, Project Fi will issue a credit of approximately $0.01 per MB of unused data at the end of your billing cycle.

What Add-ons or Bundles are Available?

All Project Fi plans include voicemail, call waiting, conference calling and access to a suite of apps to manage your account and features. 

No add-ons or bundles currently exist to customize your service.

Can I Bring My Own Device?

Phone support for Project Fi is limited. They support the following options for brining your own phone:

  • Pixel/Pixel XL
  • Pixel 2/Pixel 2 XL
  • Android One Moto X4
  • Nexus 6/6P
  • Nexus 5X
You'll also need to be sure the phone meets the following requirements:
  • The phone must not be on the ESN/MEID/IMEI blacklist
  • The phone must not be locked to another carrier network

You can find out more in the Supported Devices section of the Project Fi FAQ.

Do They Require a Credit Check?

Maybe.

There's no need for a credit check if you plan to pay for your phone upfront or bring your own phone.

If you want to take advantage of no-interest phone financing, they will check your credit.

At the time of writing, this is a "hard" credit check. This means the check will likely appear on your credit report.

To run the credit check, the carrier will need:

  • Your name
  • Current address
  • SSN

In some cases, a government-issued ID--such as a Driver's License, State Identification Card or Passport--is required as well.

NOTE: Credit checks from carriers that pull your credit bureau report may impact your credit score. If you're not sure the best options for your credit profile, we suggest contacting the carrier directly before attempting to obtain service.

What About Activation and SIM Fees?

There are no activation or SIM fees for Project Fi.

Do They Charge an Early Termination Fee?

No.

However, if you have a remaining balance a device financing plan, the total is due at the time of cancellation.

Can I Port My Number To or From CREDO Mobile?

Yes! They follow all Local Number Portability guidelines--allowing you to transfer numbers both in and out of your account.

Requirements include:

  • The accounts your are transferring to or from must be active and in good standing.
  • Local Number Portability rules must apply to the areas from which you wish to transfer the number.

This service is provided for free. However, if you are porting in a number after the line of service is already activated, you might incur number changing fees. There may also be fees for porting out from your other service provider.

You can find out more information at the Switching to Project Fi section of their FAQ.

Will They Unlock My Phone?

All phones sold through the Project Fi store are already unlocked!

Tom's Guide

A trio of networks into a first-class wireless service

from Tom's Guide

Project Fi is by no means the cheapest carrier out there. If you eat up a lot of data, Google’s service can get quite expensive fast, even with end-of-the-month credits for unused data. Discounts on multiple lines are also modest compared with other prepaid carriers like Boost and MetroPCS, and everyone draws from the same pool of data on Project Fi.

I’ve been using Project Fi for about six months now and it’s been great. I was concerned about the constant switching between cell providers, but it’s been incredibly seamless. I’ve also been able to call my cousin and brother who both live abroad and it only costs $0.01/min. I keep wifi on all the time and my data usage is usually under 200mb a month, so my cost for service is about $17/m (before my phone payment). Definitely happy I switched from AT&T!
