A Private Unblocking Key (PUK) code is a safety measure utilized by cell community operators to guard SIM playing cards from unauthorized use. For those who enter an incorrect PIN code 3 times, your SIM card will probably be blocked and you will have to enter the PUK code to unblock it.
PUK codes are usually offered by your cell community operator while you buy a brand new SIM card. It’s also possible to discover your PUK code by logging into your on-line account or by contacting customer support.
