The PIN or "Personal Identification Number" code is an access code that unlocks the SIM card for use on the network. It's composed of 4 digits and you should have received it with your SIM card .

SIM cards usually have a default PIN that is something like 0000, 0123 or 1234. If those common defaults don't work, and you don't know your PIN, you can contact Public Mobile and ask them for this.
