how to PUK unlock?

[bikramsaha2]

Mine is a Samsung I bought in Singapore. The message seems like carrier locked.  I don't have any service with them anymore.  But I will try calling Samsung and hope they can help.  thanks and wish me luck

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

If 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/xYpc_I 
            **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)
