Yes, the models support the same cellular bands.
Verizon even whitelisted all iPhone 6/6+ IMEIs from other carriers but reportedly the 6S/6S+ IMEIs haven't been added to their system yet. If Verizon doesn't activate an IMEI directly, you can always just swap your SIM. (as per the Upper 700MHz C Band terms you can use your plan on any device compatible with the network)
