what was the exact error message? Depends on the message, you have to ask the PUK code from different places

As it is a Samsung and if the message is "SIM network PIN blocked. Enter SIM network PUK." , 
      call  Samsung 1-800-726-7864 for a master unlock code.
      The only info you will need to provide is the IMEI and where the phone was purchased

If the message is “PIN unlock key (PUK)” or "Enter PUK Your SIM  Card, SIM cannot be accessed" or on an iPhone's status bar showing  "Locked SIM"
         open message support here: https://productioncommunity.publicmobile.ca/t5/notes/composepage/note-to-user-id/22437
          or use this direct link to open Chatbot ticket:  https://urlshortner.tiia.ai/Oyn1L6
            **Monitor your Community inbox (envelope icon on the top right) after the ticket is opened.  CS Agent will reply to you there.

If the message is "SIM network unlock PIN" or "SIM ME lock code NP" or "SIM not Supported" or on an iPhone's About->Carrier Lock showing "SIM locked"
          You have to ask the carrier where you got the phone from for the carrier help unlocking it.
           (Sorry, for this particular issue, PM support would not be able to help)

What is the exact message that your phone is showing?

It looks like that you Galaxy S7 may be locked to your previous carrier?  When and where did you get the phone?  You could contact pervious carrier to get unlock SIM code. It should be a free process
