Samsung Firmware Updates

Hm... so if I get a Verizon Samsung phone and a RedPocket VZ SIM, would I get Verizon firmware updates for the Samsung phone?

I would think so as long as the phone isn't modified or rooted. My note 4 gets updades while on CN and my wifes note 4 gets updates while on Ting, but those phones are using the original sprint sim cards. I have a note4 using a redpocket ATT sim but that phone is rooted so I can't do the over the air updates.
