I'm glad I found this topic. I ordered my
Nexus 5X phone - 32GB, carbon color - on Black Friday when Google cut the price by $80. Then the next day I decided to try
Project Fi and signed up. The SIM card came the other day and now the phone's up and running on Fi.
My older phone is a 15 month old Nexus 5. With a sweet T-Mobile talk/text/data prepaid plan - $30/month - I've had for 3+ years. Yes, I'm all about buying unlocked phones and not having mobile phone service contracts.
So now I've decided to try Project Fi. It's competitive as to pricing, and I like that it uses the Sprint network as well as the T-Mo network. In my domestic travels I've been in places with terrible T-Mo reception so I think adding Sprint - and wifi - should make that better. Also, foreign travel looks like it could be easier with Project Fi. (I'd have to seriou$ly upgrade my T-Mo plan to take advantage of their foreign text/calling features. No thanks.)
I'll be taking both phones around town with me today as I run errands, to compare signal strength. I still have nearly a month left after the last T-Mo topup so there's no rush to deactivate the Nexus 5.
About the Nexus 5X. I like it. It's just a tad larger than the Nexus 5, and the camera is better. I really don't want a phone as big as the Nexus 6P, but the new phones keep getting bigger all the time. Which is why I decided to jump on the 5X.
I haven't set up the fingerprint reader, but its location on the back is very handy. Big disappointment: the 5X battery life. So far it's not much better than my 15 month old Nexus 5.
I plan to sell the Nexus 5 after I'm done with the T-Mo service. it sounds silly, but although the battery life isn't fabulous, overall I've really liked that phone and I'm not in a hurry to get rid of it. But I assume that after a week or so of using the 5X, I'll be OK with letting the Nexus 5 go.
