A Quick Look at What You Will—And Won’t—Get with Google Fi

Considering switching to Google Fi? You should: It’s feature-rich, inexpensive, and transparent. But it may also not work fully with your smartphone. So let’s see how this plays out, using a few obvious examples.

As a bit of background, I use and strongly recommend Google Fi—previously called Project Fi—though I had only one (major) caveat to that recommendation to date: Until this week, the service was only compatible with a small selection of mostly Google-branded handsets. So if you used an iPhone, a Samsung Galaxy, a OnePlus, or virtually any other non-Google Android phone, you were out of luck.

Well, that just changed. Effective immediately, Google Fi is now compatible with iPhone and most Android handsets. The issue is that you won’t necessarily get the full Fi experience on phones that weren’t designed specifically for Fi. These phones—which include the Pixel 2/2 XL, Pixel 3/3 XL, the Moto G6 and Moto X, and the LG V35 ThinQ and G7 ThinQ, include special networking hardware that lets them seamlessly switch between networks, a key Fi benefit. (In the U.S. those networks are T-Mobile, Sprint, and U.S. Cellular.) You also lose some other features, like the Fi VPN.

So let’s compare and contrast. Let’s see what Google Fi features are available across three phones I’ve used in recent months: The Google Pixel 2 XL, the OnePlus 6T, and the Apple iPhone XS.

Google Pixel 2 XL

Unlimited talk/text for $20 per month. Yes
Data for $10 per 1 GB per month. Yes
Bill protection at 6 GB per month. Yes
Full-speed data to 15 GB per month. Yes
Group plan. Yes.
Free international data roaming. Yes
Free international texting. Yes
Affordable international phone calls. Yes
No contracts. Yes
Seamless switching between cell networks and Wi-Fi hot-spots. Yes
Automatic VPN protection. Yes
Data-free SIM cards for other devices. Yes
Googe Fi mobile app. Yes

The Pixel 2 XL is fully Fi-compatible, so you get the entire range of Google Fi functionality.

OnePlus 6T

Unlimited talk/text for $20 per month. Yes
Data for $10 per 1 GB per month. Yes
Bill protection at 6 GB per month. Yes
Full-speed data to 15 GB per month. Yes
Group plan. Yes.
Free international data roaming. Yes
Free international texting. Yes
Affordable international phone calls. Yes
No contracts. Yes
Seamless switching between cell networks and Wi-Fi hot-spots. NO
Automatic VPN protection.  NO
Data-free SIM cards for other devices. Yes
Googe Fi mobile app. Yes

The two key missing pieces here are the lack of seamless network switching and lack of automatic VPN protection.

Apple iPhone XS

Unlimited talk/text for $20 per month. Yes
Data for $10 per 1 GB per month. Yes
Bill protection at 6 GB per month. Yes
Full-speed data to 15 GB per month. Yes
Group plan. Yes.
Free international data roaming. Yes
Free international texting. Yes
Affordable international phone calls. Yes
No contracts. Yes
Seamless switching between cell networks and Wi-Fi hot-spots.  NO
Automatic VPN protection. NO
Data-free SIM cards for other devices. Yes
Googe Fi mobile app. Yes

The two key missing pieces here are the lack of seamless network switching and lack of automatic VPN protection.

But Google also notes that iPhone users will need to make a manual configuration change for text messaging to work correctly, something that is common with mobile virtual network operators (MVNOs) like Google Fi. That said, iMessage works fine.

Also problematic, there’s no visual voicemail support on Google Fi. To make up for this, Google will text message you a transcription of each voicemail you receive, which is nice.


I’ll start testing Google Fi with my OnePlus 6T starting this week. I’m excited by these changes, and I had never expected an improvement this dramatic.

    <p>It would be really wonderful if you could provide some clarity on how this affects the wifi based calling/texting. I have used Fi now for 2 years because were I work and live there is no cell connectivity and I rely on my phones ability to make/receive calls and texts over wifi. Previously we had to use a ATT micro cell and that was a nightmare. If it still worked on wifi and all I had to do was restart it to get it working on the cell signal again I would be looking at the note 9 or a one plus when its time to upgrade. </p>

Just saying if your current phone/carrier supports WiFi Calling (AT&amp;T, which I have, does), that would be a simple solution for you with any phone that does not require a femtocell, new carrier, or new phone and should be able to transition easily between in home WiFi and LTE outside of your home (as long as you DO have LTE signal outside your house). If the LTE signal does not kick in at your door, then this will not work…</p>

      <blockquote><em><a href="#374086">In reply to GilesBrule:</a></em></blockquote><p>I have been using WiFi Calling on my iPhone 6s (and now a new XS) on AT&amp;T for 3 years now (it has been supported for longer) with seamless transition between WiFi and LTE. I was using this back when I had Xfinity as my Cable Internet provider, and now with Century Link as my Gig Fiber Internet provider. How is this solution (Google-FI), that uses subpar carriers as out of home carriers (T-Mobile, Sprint, and U.S. Cellular), doesn't transition between WiFi and LTE, requires modifying standard settings for texting to work, does not support Visual Voice Mail, requires me to have all my data mined and filtered by Google, is an MVNO instead of a major carrier, AND costs in my case actually more (I use over 10 GB a month on my iPhone) better? All the Major carriers (Verizon, AT&amp;T, Sprint, T-Mobile) support WiFi Calling with current hardware by multiple manufacturers. All you have to do is toggle the WiFi calling feature on in Settings&gt;Cellular&gt;WiFi Calling and you will use WiFi and international roaming over WiFi on MOST carriers without any of these silly limitations…</p>

    <p>They need better pricing. I was on Fi but I turned into a data cheapskate and was driving myself nuts turning data off. In the end I wasn't saving much money. I went back to Straight Talk (Verizon network) and for $50 I get unlimited data (throttled at 60GB). </p>

I have a three-person family plan and we typically use ~20GB per month (of a 30GB plan). Google Fi would cost us $170 ($56 per person), which is right inline with what we're paying AT&amp;T. I didn't realize until just now that Fi also offers free data-only SIM's which is a nice bonus I'll have to keep in mind as I look at connected devices over the next year (iPad, Surface, Apple Watch).</p>

    <p>I see no point in having this without the switching between wifi and cellular networks. The whole benefit of this thing (to me) is the aggregation of multiple signals to make a stronger MVNO out of two lesser networks. Am I missing something here?</p>

      <blockquote><em><a href="#374094">In reply to ChristopherCollins:</a></em></blockquote><p>The other thing that's of interest for many users is the pricing model and the transparency. You only pay for the data you use. You don't worry about a crazy overage charge (e.g. AT&amp;T charged me $15 per GB when I exceeded my family plan allotment) nor do you feel like you're wasting money paying for data you're not using (e.g. my bill is no lower if my family uses 3GB one month rather than the usual 15-20GB).</p><p>That said, you have to look at your usage history and map out some typical scenarios to see whether the ultimate costs are better than what you currently have. And this will also vary depending on whether you have a family plan because Google Fi has different rates and thresholds in that case.</p>

    <p>This is a super major win for smart phone users (in general). More carriers, more competition….lower prices. Even technically, Google isn't going to be a provider, ….the more sellers, the better.</p><p><br></p><p>The best is of this service is the free international roaming. For the most part, no need to purchase a foreign sim card, or at least that's my experience. </p><p><br></p><p>Now I'm wondering….hmmmm…… How come Google ditched the word "Project" in "Project Fi?" Was the word and reputation of Project just so bad that Google had replace it with its own name brand? LOL.</p>

This will make it easy. Now that we can use the phones we already have, this seems to be a no brainer.</p>

    <p>What’s the privacy implications? Seems with more people using mobile devices google wants that data. Who you call, who you text, where you go, what you browse, where you shop, what you buy, a world where all traffic and communication goes through Google owned services. A company that makes money from the data they collect not the phone service they offer. They can stop paying Apple, or anyone else, because now it all will go through them. BTW: don’t get to excited about claims that the service anonymizes data it collects. They all do…but when later aggregated with other data, google and 3rd party syndicated data, they know everything. I’ll pass!</p><p><br></p><p>UPDATE: read the privacy policy and terms and conditions, they even speak to the 3rd party data I mentioned above,…I’ll DEFINITELY PASS! </p>

As an iOS user I have that already and Apple isn’t selling my location data or marketing goods and services to me using it for the privilege. Hey you, and others may not care and that’s fine, you decide what’s best for you. But this reminds me of smart TV’s and why I never connect them to Wi-Fi. Your cable company, by law, can not sell your viewing data. That’s why Nielsen still exists. Samsung isn’t under those laws so they can collect anything and are free to sell it.</p>

    <p>Pass for us. We are on the (old folks) 55+ T-Mobile Unlimited plan. Two lines at a flat 60 bucks a month. Based on our usage (running about 3-4GB/mo each), I think we'd land up a bit above 60/mo if we were to switch. </p>

    <p>Without the ability to switch between networks this kinda defeats the point of the service given most carriers unliminted plans these days. With T-Mobile I get 2-lines w/unlimited data (throttled at some point) for $100 a month. I don't have to worry about overages so the data protection cap on Fi doesn't mean any thing to me. If I travelled internationally more that would be of value but I don't typically travel outside of the US that much. </p><p><br></p><p>So, unless both my wife and I switched to phones (likely the Pixel 3) that fully support the switching I ultimately end up with a device that is still going to use a single carrier signal (though which one it is; who knows?) and I'm now speed capped at 15GB. </p><p><br></p><p>When I saw the news it certainly got me curious but since both my wife and I are using Samsing devices on T-Mo there doesn't appear to be any value in us changing for now. Perhaps if we go Pixel in the future we might kick the tires. </p>

    <p>I'm a current T-Mobile user here who moved from Fi a year ago. There was a lot to Fi that was very attractive, including multiple networks, hangouts on the PC, and predictable pricing. Phone choice, or should I say the lack of choice, was the limiting factor which ultimately drove us away. Now that's changed.</p><p><br></p><p>But I don't think it makes sense anymore. It seems that without network hopping that Google Fi is more or less an MVNO on the T-Mobile network. With a family of four on T-Mobile One and our monthly data use of more than 20GB, there is no money to be saved switching. (T-Mo also picks up Netflix for us). So the benefit comes down to hangouts on the PC for messaging (does that still work?) and international roaming. Am I missing something?</p>

    <p>I don't fully comprehend what 'seamless network switching' means and what my experience will be like, having been with Verizon since 2004. Will Fi work seamlessly on Verizon's networks? I'm open to switching to Fi on a OnePlus 6T (or future OnePlus phone), but I need to be confident that my service will be equivalent to what I've gotten from Verizon for the last several years. I'm happy with Verizon's coverage and quality of service, just not the monthly bill.</p>

I guess the real question is, whether those carriers have equivalent coverage in the areas where you regularly use the phone.</p><p>It also seems very expensive, from a European point of view. I pay $34 a month (including tax) for unlimited calls, SMS and data, with the first 10GB at full speed, throttled after that, although I can buy 1GB booster packs for a few dollars to get full speed again, if I go over my limit, although I've always come in well under 10GB. And that is expensive, there are more expensive plans offering less, but there are also cheaper plans that now offer more – I've had the contract for nearly 2 years and prices have come down somewhat.</p>

    <p>Is this any different than it used to be? I think you could always put a Fi SIM into any unlocked phone, and you'd get as much T-Mobile service as that device would get with a T-Mobile SIM.

    <p>Paying $10 per Gb just seems so absurd to me… here in IKEA-land, the going rate is anywhere from $0.20 to $0.50 per Gb, depending on your plan. This includes free roaming within the EU, but not internationally – which is probably the one thing that Google Fi has going for it. But I do believe Google has to adapt their pricing to the market if they want Fi to succeed outside the US.</p>

T-Mobile doesn't offer a 1 month data pass option for pay-as-you-go customers. The upside though is I don't <strong><em>have</em></strong> to buy any data so I typically go for a month or two without any data then just buy a single data pass for an upcoming trip. End result is most months I only pay $3. Wi-Fi is almost everywhere for free and provides the majority of my data needs.</p>
