You run ONE system in a particular region on a particular band.

Verizon 3G uses CDMA EV-DO. Not GSM at all.
Verizon didn’t go GSM until they added LTE but even then, they used CDMA for voice in the beginning. It wasn’t until later that they added support for VoLTE (around 2014, I think?).
Even after the advent of LTE, Verizon and Sprint had the very annoying habit of only allowing/activating whitelisted devices on their network (despite the FCC mandate on Verizon’s 700MHz spectrum purchase). It’s only in later years when that practice has changed.
