i have an old verizon phone someone gave me.

Can i just get a new sim card & activate it even if they still owe a bill?

Depending on the phone, it probably doesn't have a SIM. Verizon uses the IMEI to identify the phones. Kind of like PC's and MAC address's for networks.

Verizon doesn't use sim cards in the USA only overseas.
If the meid number is blacklisted then no.
