This is from specs of the international version - it is not compatible with Verizon for the same reasons I stated above
WCDMA does not equal CDMA !!!!
WCDMA is GSM terms for HSPA and HSPA+, it has nothing to do with Verizon's and Sprint's CDMA and is not interchangeable.
As stated, the phone you bought is not compatible with Verizon at all. It will not work.
It has no CDMA
It has no band 13 LTE
