Can a unlocked iPhone 7 be both GSM and CDMA?

Can a unlocked iPhone 7 be both GSM and CDMA?

Let's defined unlock because it can mean different things.

Apple calls it sim-free when it has both GSM and CDMA or if you buy the Verizon version. So if you buy the sim-free or Verizon version from the apple store then it has both cdma and gsm.

If you buy a phone that was previously locked by AT&T but then became unlocked because the buyer paid off the phone so in this instance, it's a gsm phone because AT&T uses GSM.

Well I'll be damned, they actually do exist.

No, If its GSM unlocked you can use gsm network, if CDMA its only for CDMA
