After years of being an AT&T mobile customer, dating back to the Cingular days, I finally made the jump to Google’s Project Fi last December. All in all, the service has been very good, and the savings have been ridiculous. AT&T and Verizon have recently rolled out unlimited data plans, so the pricing is a little different than the plan I was on, but it’s not too dissimilar from what I had. Note that I do not recommend project Fi if you’re a really heavy cellular data user (> 6GB total) because they charge $10/GB. If you’re using a lot of data, that will add up fast. However, the problem with most plans is they don’t give you anything if you don’t use that data (maybe you get rollover data, but I’d rather have money). Project Fi pays you back for what you don’t use.

With AT&T, My wife, my sister, and I had a family share plan with 6GB of data. The total for this plan was right around $210/mo, and that was with a corporate discount applied. All of us had new-ish smartphones (my wife and sister had iPhones, myself an android), and were coming up on the end of our 2-year contracts.

During my attendance of That Conference last year, I heard someone tell me about Project Fi and how little it cost. I started looking into it and when my phone (LG G3) turned itself into an unbootable brick one day in September, I decided to buy a Nexus 6P as a replacement. Not only was the phone reasonably priced, but was one of the very limited selection of phones that work on Project Fi. It took a little convincing of my wife to move from her iPhone to Android, but when they announced the Pixel, she agreed to make the move.

Cell Coverage and Quality

A few months in, I can tell you the service, at least where I live in Madison, Wisconsin, has been very good. I haven’t had many instances where I couldn’t get a signal. From the Project Fi FAQ:

Project Fi has partnered with Sprint, T-Mobile, and U.S. Cellular, three of the leading carriers in the US, to provide our service.

They also provide a link to a coverage map:

Project Fi also tries to utilize WI-FI calling when there is low cell quality. I have found this to be a bit of a mixed bag – I sometimes don’t get a dialtone or the phone doesn’t indicate that a call is going out until, suddenly, someone picks up.

The only places where I’ve noticed signal quality problems so far have been inside airports. In particular, it was difficult to get a signal at O’hare. Other people I was travelling with who had Verizon received a better signal.

I have also noticed that sometimes SMS messages won’t come through unless I enable cellular data (and yes, I have verified this even when messages are not MMS). My wife hasn’t had the same problem on her pixel, so mine could be a hardware issue or something specifically related to the Nexus 6P.


Getting back to the costs, our bill comes in at around $45/month. For two people. Previously, it was costing about $140/month for two people. That’s almost $100/mo, we’re saving. Because Fi reimburses you for unused data, it incentivizes us to use less than the 2GB we pay for. I even have a little widget on my phone that shows how much data I use, and it really encourages me to think about how I’m using data.

Here is a breakdown of the charges from my last bill:

Last month’s usage (for Feb 2 – Mar 2)
Unused data Credit for 1.666 GB at $10/GB -$16.65
Next month’s charges (for Mar 2 – Apr 2)
Fi Basics 2 people, $20 + $15/member $35.00
Prepaid data 2 GB at $10/GB $20.00
Taxes & regulatory fees $6.12

Total: $44.47

International Calling

One of the other great benefits of Project Fi is the international calling aspect of the plan. Data is still $10/GB in 135 countries. From their FAQ:

Project Fi offers high speed data in over 135+ countries and destinations for the same $10/GB you pay in the U.S. For a complete breakdown of specific countries please check our International Rates.


Unlimited international texts are included in your plan. If you’re using cell coverage, calls cost 20ยข per minute. If you’re calling over Wi-Fi, per-minute costs vary based on which country you’re calling and you’re charged only for outbound calls. Please check our international rates for more information.

I haven’t had a chance to try it out, but I love this part of the plan. When I traveled to Belize last year, we paid $20 for a SIM card and calls there are generally very expensive. Data is incredibly expensive. Had I had Project Fi at the time, those charges would have been very minimal (coverage is another issue altogether, but at least when you have coverage, usage comes at a reasonable rate).


So, in summary, if you’re a relatively low cellular data user and don’t mind having Google phones, this plan is a great value. I’m looking at saving nearly $1200 this year because of it. I can think of a lot better things to do with my money than spend it on cellular service.
