Isn't CDMA required to work on Verizon? I thought that's what I was told. If the Key2 will work with Verizon, great. If not, sad. Thanks.

CDMA is not required to work on Verizon. Most of their network has been overlayed with LTE by now. You may encounter some VERY rural places where LTE is not working yet, but those are few and far in between. CDMA will be shut down completely between 6/2019 and 12/2019 anyways.
