I got an invite to Google's Project Fi. I've been looking for a reason to tell Verizon to go fuck themselves, and this gave me the opportunity. I'm only two days in, but so far, so good. I've been on a call and switched from voice over wifi to LTE seamlessly (turned off wifi to see what would happen). It's cheap. $20 per month + $10 gb , and you get a refund for any data you don't use. The only downside (for me) is the only phone available right now is the Nexus 6, which I find a little too large - otherwise I really like the phone. It works off T-Mobile and Sprint. Thankfully I don't believe I've yet been connected to Sprint, although there is no way to know for sure. T-Mobile is actually pretty good where I live (I tested them for two weeks a while back and got speeds around 20-30 down, 5-15 up). The battery seems to hold up well despite the switches from data to wifi.
Worth noting that I spend 99% of my time between New Haven and NYC, and rarely venture too far outside the 95/Merritt corridor. Yes, I lead a boring existence, you don't need to tell me. Even in a place like Weston, where my friend sort of lives in the sticks, I got good service. When I have to visit my sister upstate I imagine the service will kind of suck. We'll see in a couple weeks. I don't think I'll get any service when I go on my yearly golfing trip to Vermont, but I didn't get any with Verizon either.
If you live in an urban area where TMO is strong, I'd look into it. It cut my bill from about $115 or so per month to somewhere around $50.
My ETF with VZW is $120. Does anyone know if I can mail it in the form of a giant novelty check or something equally inconvenient?
