I've been using Fi on my Nexus 5x since November and here is my mini review on Fi.
All in all I like Fi, but I do not love it. I came from an unlimited data plan with 2000 shared minutes on Verizon with usage ranging from 10 GB to 30 GB a month. After Verizon added the $20 a month addition to my part of the bill was paying $110 a month for my single line. I was able to buy a 32 GB Nexus 5x with Nexus Protect and break even after a year on Fi. Over a two year period on Fi I will save $1,400 compared to Verizon, assuming I wouldn't buy a new device on Verizon within the two year period. I was using a 2013 Droid Maxx DE (manufactured June 2014).
I had to seriously reconsider how I spent my data as Fi data is expensive. This has been a good thing as I don't use my phone for none essential things while I'm not on WiFi. I have been able to keep my data usage below 1 GB every month except the current month as I have been traveling a lot in non-WiFi areas. All of my leisure phone data is consumed while on WiFi.
Pros:
- Fi is cheap if you have access to WiFi.
- Google support is great. It is fast and polite.
- Coverage is a combination of networks*
- WiFi calling*
- No more waiting for carriers to approve updates. My Nexus gets updates within two weeks of being announced from Google.
- Data only SIM, I don't use it, but I like the no fees approach to only use data on a device.
- Hangouts integration, it is really nice to have all of my devices ring when I get a call or message.
Cons:
- If you use more than 5 GB of data a month and don't have access to WiFi, Fi will be expensive.
- Coverage is a combination of networks, but the networks are all subpar. Fi cannot come close to Verizon's coverage. Anywhere off a main highway I am bumped to 3G and in rural areas I have no service. I spent Thanksgiving in NH and didn't have access to WiFi. I went three days without having any service at all and couldn't make or receive any calls. Luckily my wife had her VZ Droid Maxx DE in case of an emergency, which also had LTE where we were. I have the same experience in VA, NC, and SC.
- WiFi calling. When my phone makes a call over WiFi it is great, but it never wants to connect over WiFi. My main residence has no cell signal in the house and FIOS for internet. I can sit next to my router with max signal and my Nexus will still try to make a call over my cell network, which only has 1 bar. I have all the settings set to make a call over wifi whenever possible, but it doesn't happen very often. Google recognized the error early on as a glitch with the 5x, but it has barely gotten better.
- Call quality over the network is ok.
I will continue to use Fi because I like how cheap it is, but I have considered going back to Verizon on multiple occasions due to reliability. I ride motorcycles and don't like not being able to make an emergency call if something happens. Now that Nexus phones work on Verizon's network without hiccups, Verizon is much more tempting.
BTW, I have never had the speeds you have been talking about on Fi.
