Can't determine if that phone would work seeing as how it doesn't exist yet?
At least as far as GSMArena and PhoneArena are concerned.
As far as I know, Verizon still uses certain 3G frequencies for certain underlying features of their services, so while any phone that is unlocked will work for the most part on their network, any underlying feature that requires use of said specific frequency on the 3G band won't work properly.
The frequency is 800MHz on 3G. (for CMDA)
(Most unlocked/GMS/International phones only support the 850MHz band instead because Verizon is a b-word like that and did this on purpose)
If a phone doesn't have support for that frequency, then it won't 100% work on the network, but will still work in regards to phone calls, SMS, MMS, and 4GLTE things as long is supports the necessary other frequencies for that (which most do).
Best thing to do when looking at different phones, is (in the event it's not a Verizon model) go to either GSMArena.com or PhoneArena.com and look at the specs of the specific device (when looking at a phone, you have options to look at the different carrier/unlocked model numbers) and cross check the supported frequencies with that of what is required for Verizon's network.
Verizon's network is the following.
3G CDMA 800, 1900 PCS (frequencies)
4G (LTE) Main bands 2, 4, 13, 66
4G (LTE) Secondary additional bands (note absolutely necessary but good to have support for some of these too)
5, 46, 48
Frequencies used by Verizon for their 4G (LTE) services
1900MHz (Band 2)
1700MHz AWS-1 (Band4)
1700MHz Extended AWS (Band 66)
850MHz CLR (Band 5)
700MHz C (Band 13)
Making sure the phone you decide to get supports the main bulk is important for 4G LTE
1900MHz (Band 2)
1700MHz (Band 4, 66)
700MHz (Band 13)
850MHz (Band5) is used very little and you can for the most part live without it, but if the phone supports it great.
Having support for all the other things is great to have if you want it to properly support services that are on the 3G band, but you can get by without them.
So again, keep in mind just the main important bulk of needed bands and frequencies, then cross check that with what the phone supports using either website.
