Verizon probably won’t accept phones sold as GSM even if it supports CDMA in theory.
 
US CDMA phones work differently from Asian ones. I don’t have the exact implementation details but it seems to involve writing MEID/ESN or security keys directly into the phone and register then with Verizon network at factory, due to technical or policy reasons they probably won’t do that for phones already sold.
 
Although most networks have already moved to LTE, which uses SIM card, not data written into the phone for authentication and are planning to decommission CDMA altogether, I’m not sure whether this factory pairing data is still required.
 
Sprint might be worse, check with your carrier's support regarding details.
