No, none of the OnePlus devices nor the POCO will work on Verizon. The POCO doesn't even properly work on AT&T and T-Mobile.
From an AP article about this, "A bigger issue is the cellular band support. This phone is intended for Asian markets, so your connectivity in the US will be mediocre. There's no CDMA for Sprint or Verizon, but that's no surprise; plenty of unlocked phones lack that. The 3G band support is only optimal for AT&T, but LTE is going to be a problem. The Pocophone F1 has band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800), 38(2600), 40(2300), 41(2500). Band 5 is the only one on that list active in the US, and it's just a supplementary band for AT&T and T-Mobile. You're going to have very poor connectivity with this phone in the US."
