GoogleFi

I have not, but my son does and really likes it. Full disclosure, though, he does work for Google.

There are still not many phones that work with Project Fi. That's one reason I haven't considered it. I have no interest in getting an expensive phone just to get the service. There are plenty of other affordable mobile plans that work fine with cheaper phones.

At the moment, Sprint's 1 year "BYOD free unlimited everything" is still the best deal going. I switched in January and have been paying about $3.80/month in taxes and fees (varies by the local tax on cell phone service where you live). Sprint has the same international roaming plan that T-Mobile has (2G data which could be slow for some, probably good enough for many). You do have to have a compatible phone and port in existing service, but it's pretty easy to do. I bought a brand new unlocked Moto E4 and activated a Ting SIM card for about an hour to get "existing service" and a phone number to port in to Sprint - that's all I needed to do. (Plus spend $10 to buy a Sprint SIM card for my phone.)

A relative has it and it's far less than satisfactory. Per field testing, the required device is less than perfected and signal strength weak compared to users with Verizon and AT&T in my area. Will future iterations be significantly improved? Hope so.

The "best plan out there" ... with 2G ... LOL.

Presumably you mean Sprint (and T-Mobile). Yes, it is fast enough for many people. On my recent trip to Portugal, I did spring for 10 euros for eight days of fast data on my Dutch Vodafone SIM, but had it cost much more than that, I would have lived with 2G data just fine. I still come out way, way ahead using my Vodafone SIM when I travel vs. Google Fi.

"Expensive phones." Their low end phones have always been 200-250, except for a short period where they were out of stock. Wow, breathtakingly expensive. And with $100 trade-in value 2+ years later. What person who can afford to travel in Europe can possibly afford a $250 phone.

What person who can afford to travel in Europe can "afford" a $500 phone? Or a $1,000 phone? Probably just about everyone. Sorry, just don't get your point here. Just because I can "afford" something doesn't mean it's worth spending the money. I saved about $150 by not buying one of the Google Fi phones. I only bought the Moto E4 (a phone that serves my needs just fine) for the price because I got a free year of Sprint with it - well worth the cost. My phone service will cost far less than yours for a year. Saving money may not be important to you. Personal choice.

Some people complain about coverage in the US, see above. In my experience everywhere I have used it in the US it has worked just fine, as it rides on the Sprint, TMobile and US Cellular networks.

Sprint coverage has yet to be a problem for me. Coverage in rural areas is spotty, but so is T-Mobile's. If I really didn't care about the cost of service and needed reliable coverage even in obscure rural areas, I'd be with Verizon, not Google Fi or Sprint or T-Mobile.

I use it, and taken it abroad. If you have the right phone it is a great value. Voicemail transcribed to text is another very useful feature, though I suppose other plans offer that.

My phone worked seamlessly in France, I did not have to do anything special.

I use Fi and recently upgraded from the Nexus 5X to the Moto X4 for $155 with trade-in, same deal as Kaeleku posted about. I chose to pay $10/mo with no financing fee. Aside from the phone charge, my monthly bill is about $24.

Last year I used my phone for navigation and occasional Internet lookups for 3 weeks in Scandinavia. I had regular cellular service everywhere we went (WiFi while in hotels) and I ended up spending about $8 more on data than if I'd stayed home. This year, we took a Caribbean cruise, and I had service in every port. I did get an alert while we were sailing past Cuba that there's no plan there.

I'm a happy Fi customer. I see you've already signed up, so it might be too late for this, but every Fi user has a referral code that can save you and the referrer each $20. Send a message to me or track down some other user if you need one.

Ty CathyA. We did get the $20 off, ordered the Moto X4. How are you liking the phone itself?

I like the X4, but to be honest, my requirements are pretty basic. It runs my apps, connects to my car, takes decent photos, and has enough storage for my music and podcasts -- so it does everything I need. I've read reviews that said the camera is not great in low light situations, but it's not something I've noticed personally.

I do like that it gets the monthly Android security updates, but I got bitten by that once when an update broke a mapping app I use while hiking. The next month's update fixed it, but it was inconvenient to be without it.

I think the Moto phones are a great value. I'm very happy with my Moto E4 - it's only got 2GB of RAM and 16GB of internal storage, but it's not a laggy phone at all and has a nice screen. The biggest drawback is the camera, which is a tad slow. The X4 must be just better in every way, but it isn't something I need.

Google Fi has worked for us for a couple of years now in numerous countries in Europe and the Caribbean. It takes a minute for the phone to capture the signal at touch down or docking, but once it does you are good to go with phone and data. A six-week trip in France raised my monthly bill from 25 to 35 dollars, but that was the total expense. My husband joined my plan, so now it’s 40 for the two phones. We have the less expensive Moto phones, which are fine for our purposes.

I've been using GoogleFi for a couple of years now... it has worked very well for me in Italy, Germany, France, Hong Kong, Japan, and Seoul.... no more sim card hassles and waiting in line at the local mobile stores... and I can use my own same US number all over the world... same price as back in the USA as well. I love it.

I would consider using Project Fi ("Google Fi") if they ever start supporting the phones I use. But I don't have to "wait in line" at a mobile store for a SIM anymore, either - i got my Dutch Vodafone SIM on eBay and had it set up so I had service as soon as the plane landed in Europe. And because I use Google Voice as my primary phone number anyway, I already get to use my same US number all over the world (with Google Hangouts), with or without using Project Fi. But clearly Project Fi works well for some people!

yes, i love fi. i have used it in the US, Japan, Italy, UK, Denmark, Netherlands, Thailand... everywhere i have had to travel in the past 18 months it's been great, except in australia this january, when it would only work on one specific network, and i had to keep manually switching it over, for 2 days.

i got an extra SIM for my husband, he doesn't even have an approved Fi phone, but has been able to use data on it all over the world as well (tho not voice).

I have the same problem and i am on a vacation, far away from the place where i bought it.
I have tried to reinstall twice with the factory settings.

This is probably too late for the OP, but maybe it will be useful for someone else.

I've had Project Fi for a couple of years now, first with a Nexus 5 phone and now with a Pixel 2. Ironically, the first foreign country I visited after getting Fi was - Cuba in December 2016. One of the few places that Fi doesn't work (the government has communications including cell service under its control).

I've had no problems with Fi service in the US, except one area in/near the Oklahoma panhandle, which is seriously in the middle of nowhere.

Fi worked flawlessly in the UK last year. I was based in London, with a few day trips, and never had coverage problems. I checked my billing when I got home. Maybe everybody knows this, but it hadn't registered with me until I reviewed that bill:. my calls from my hotel room to friends in the UK were billed at one cent per minute (Fi routed them through the hotel wifi), and a call I made (also to a UK number) while out and about was billed at twenty cents a minute. That call wasn't routed over wifi, just over the regular mobile system. The latter call wasn't a big deal but it's nice to know about the penny-per-minute wifi rate!

BTW, there were no extra fees for the data I used in the UK; it was all billed at the usual rates.
