Can an ATT iPhone 6s work on a Verizon network by switching SIM cards?

I have just upgraded to an iPhone Xs and own my old iPhone 6s.  I want to give it to my son who has his iPhone 5 service on Verizon.  Is this possible and  if so, does it involve anything more than adding his Verizon SIM to the iPhone 6s?

An ATT iPhone 6s will work fine on Verizon. You need to get it unlocked first. Your son will need to ask Verizon if anything more is needed other than moving the SIM card.

Re: Can an ATT iPhone 6s work on a Verizon network by switching SIM cards?

For future reference this was our process when switching from AT&T to Verizon by changing SIM cards.  I requested an unlock of my iPhone from AT&T, which was granted.  I wiped the iPhone 6s (reset to factory) and started as a new phone with the AT&T SIM card (non-active) in the phone.  We followed the prompts and set it from am iCloud backup of the old Verizon phone.  We then upgraded the iOS to 12.  Finally we swapped out the SIM cards putting the working Verizon card in the iPhone.  Within a few seconds we where on the Verizon network.  There was one glitch whereby the phone keypad did not accept input.  That was solved by doing a home button reset.  Its been fine since.  Hope the shelps.

You didn't say who does the unlocking, ATT or Verzion?

@griesgroup Whoever the phone is locked to unlocks it. In the case of the OP, it would be ATT since the phone was locked to ATT.
