Google Fi's Flexible plan is still a good deal: Here's how I've used it for the past 8 years
Google Fi Wireless—first named "Project Fi"—launched over a decade ago with a single plan. There are now four plans to choose from, but the original pay-for-what-you-use plan has stuck around. It's still a shockingly good deal in 2026.
In the early days of the internet, paying for data by the KB or MB was the norm. However, for phone data plans, it didn't become a thing until the early 2010s. Ting was the first to offer it in 2012, and Google Fi launched with the same idea in 2015. I've been using the service since 2018.
Google Fi's Flexible plan has stood the test of time
The price has never changed!
It's no secret that most things get more expensive over time. We see this all the time in the tech world with increasing monthly subscriptions and hardware upgrades. By some type of miracle, Google Fi's original Flexible plan has been immune to this.
Google's explanation of the new service in the announcement blog post from April 22, 2015 :
Here's how it works: for $20 a month you get all the basics (talk, text, Wi-Fi tethering, and international coverage in 120+ countries), and then it's a flat $10 per GB for cellular data while in the U.S. and abroad. 1GB is $10/month, 2GB is $20/month, 3GB is $30/month, and so on. Since it's hard to predict your data usage, you'll get credit for the full value of your unused data. Let's say you go with 3GB for $30 and only use 1.4GB one month. You'll get $16 back, so you only pay for what you use.
Now, let's go over to the Google Fi website and check out the Flexible plan details:
-
$20 per month for one line with talk, text, and hotspot tethering.
-
$10 per GB of cellular data in the U.S. and abroad.
The fact that the pricing is exactly the same as in 2015 is somewhat unbelievable, and yet the Flexible plan has gotten considerably better since then, too.
-
International coverage now includes nearly 200 countries.
-
5G is now a thing.
-
Select smartwatches can be added to the plan at no extra cost.
-
Spam blocking and VPN by Google are included at no extra cost.
In case you're curious, I've crunched the numbers for inflation. When I first signed up for Google Fi in 2018, I regularly used around 1GB of data—that's $30 (taxes and fees not included). If Google Fi had increased its rates to keep up with inflation, I'd pay $39 in 2026. Over the course of 12 months, that's $108.
Making the most of the Flexible plan
Be flexible with the Flexible plan
Admittedly, I haven't exclusively been on the Flexible plan since 2018, but that's part of why it's so nice. I tend to use more data in certain parts of the year, and less in others. Do the math, and it's easy to know when it's time to make a switch.
During the summer months, I'm away from home far more than in the winter months. The weather is nice, and I just want to be out doing something . Google Fi's cheapest non-Flexible plan— Unlimited Standard —is $50 per month. So, when I notice my monthly bill threatening to pass that mark, I make the switch, and I can enjoy streaming music on my bike without the data anxiety.
Then, when the temperatures start to drop again, I find myself staying at home with the warm comfort of Wi-Fi more often. If I'm using less than 3GB of data per month, it doesn't make sense to pay for the Unlimited Standard plan. That means it's time to switch back to the Flexible plan again—and the cycle continues.
Last year, I took a trip to Europe, and I knew I'd be constantly using walking directions, making reservations, translating, and just generally looking up a million things every day as a person in a brand new place. Rather than blow through data on the Flexible plan, I upgraded to Unlimited Premium. This little maneuver ended up saving me $60.
That's where Google Fi and the Flexible plan truly shine. You are free to switch between plans whenever you want to fit your needs. The Flexible plan is still an excellent deal, and when it's not, you can use a different plan for a while. It's worked pretty well for me.
