At&t code mm6 Phone not allowed

I recently purchased a Samsung Galaxy S7 Active. The phone was in good standing and I was provided an unlock code through At&t. I powered the phone on and it asked for the code and I typed it in and it said code entered successfully. When putting in a different sim , I get Phone not allowed mm6. I'm stumped and need help plz

I gather you are using this phone on someone else's Network. Verizon or one of its mvnos or Sprint or one of its mvnos cannot use that phone. Once unlocked it would work on a compatible network like T-Mobile.
