what are puk codes incell phones?

Answer 1

Personal Unblocking Key


PUC is an abbreviation for the phrase personal unblocking code used in GSM mobile phones. Most mobile telephones offer the feature of personal identification number protection. After switching on the phone, the user is (optionally) requested for security reasons to enter a 4-8 digit PIN enabling the phone's non-emergency calling functions. If the wrong PIN is typed in more than three times, either the SIM card, the device or both become locked.

They can be reverted to their original unlocked state, however, by entering a PUC, but if the wrong PUC is entered ten times in a row, the device will become permanently blocked and unrecoverable, requiring a new SIM card. Cellular phone users are therefore advised by most providers to keep their PUC written down in a safe place separate from the device.

PUC is also called PUK, the abbreviation for PIN unblocking key or personal unblocking key.

To obtain your PUC code and unlock your device and/or SIM card, you must contact your network provider (the network your mobile uses to make calls)

Answer 2

After a few incorrect attempts [maybe someone was trying to get into your phone], the PIN is invalid and the PUK has to be used. Call the company and they will give it to you... p.s. dont guess the PUK
