The very first thing you will need to do is determine which type of code that you need.
The PUK of the sim card itself is a security measure and a code that is need if you enter the sim card's secuirty PIN too many times. If this is what you need, then only Public Mobiile's moderators can give you that. Moderators can be contacted through this link: https://productioncommunity.publicmobile.ca/t5/notes/composepage/note-to-user-id/22437 .
Please note that code is not normally needed unless someone turned on your sim card's security features and then entered the incorrect sim card PIN multiple times incorrectly.
If your phone is asking for the "Sim network unlock PUK", this means that your phone is locked to a different carrier. This would meant hat the "Sim network unlock PIN" incorrectly multiple times. These codes are something that only the original carrier of the phone or the phone's manufactuer can provided. Public Mobile cannot help you with either of these. The "Sim unlock network PIN" is the actual code that you would need to make a phone unlocked so that a Public Mobile sim card can be used, but the "Sim network unlock PUK" would first need to be used to re-enable the ability to network unlock the device if the phone is prompting you for that.
Please realize that these codes are completely different things, and it's important to know which you need.
