Is there another way to unlock my Pantech P9060 phone besides the PUK code

I answered this for you already and the short answer is NO. Let me explain in a non technical way. The lock has been put on by the cellular provider at firmware level and only they have the key to the encryption lock.

They have done this because they own the phone on an undischarged contract. For instance, you or 'they (the person who had it before it was lost or stolen)' took a 2 year plan and there is a still a year to run. perhaps you are trying to use a different cellular provider on their phone, perhaps Pay As You Go.

Why did they put the lock on it?

See above, you are trying to use another company.

The phone you have is reported stolen and the cellular company are not going to use their phone. They want it back!

You have put a consumer lock code into it a stupidly forgot what the code is? Or you nice mates, baby brother have been playing with it and they have been trying to get into it. After 10 wrong tries, software automatically locks it with a PUK Code.

Here is the long explanation again, read it, it took me a while to write it as one of my TIPS. There is no other way. This has cut 'phone theft to order', and 'phone muggings' to virtually zero. If you have purchased a stolen phone, give it back and get your money back.

Tip & How-To about Cell Phones
Your phone is asking for a PUK code?

Is your phone asking for a PUK code. PUK = Personal Unlocking Key. Personal Unblocking Key, or PIN Unblocking Key.

This can only come from your cellphone carrier and usually the company that still owns the phone under the agreement. Sometimes it is because you have put another SIM card in it, and they own the phone and need you to use them as carrier to get the price of the phone back, or you are in default of payment, or on a Pay as You Go plan, it is over expired. I can also happen if you have entered the unlock code wrongly three times. This often happens when a phone is stolen or lost and has been found by or sold to someone else who then try and use the phone. Wikipedia A personal unblocking code (PUC), also known as a PIN unlock key (PUK), is used in 3GPP mobile phones to reset a personal identification number (PIN) that has been lost or forgotten.
Most mobile telephones offer the feature of PIN protection. After switching on the phone, if the PIN security function is active, the user is requested 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 returned to their original unlocked state by entering a PUC, provided by the service operator after verification. 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.
The PUC (PUK) is a SIM-specific code assigned and provided by the service provider.
Once you enter the PUK code, you must set a PIN. The PUK and PUK2 are used to unlock the PIN and PIN2 codes respectively if your SIM card is blocked
From Bell
The PIN unblocking key (PUK; sometimes called personal unlocking key) is a master security code for unblocking and resetting the personal identification number (PIN) for your SIM card. For added security, the PUK is unique to your SIM card. If your PIN code is active and you enter it incorrectly three times, your SIM card will be blocked. You won't be able to use your phone, except for emergency calls. You must enter your PUK into your phone to unblock the SIM card. If your SIM card becomes blocked, Contact us to get your PUK.
You may be able to do it from the website or your cellular provider. This is from Orange - T-Mobile in the UK.
Your phone can become blocked in a number of ways - one of them is if you enter your SIM card PIN number incorrectly three times in a row. To unblock your SIM card, you will need to use something called a PUK (Personal Unblocking Key).
Remember that unblocking is different to unlocking. Read more information on unlocking your device.

Hey..!,do you know samsung sgh x700 fdn mode puk code....?

These directions are for an AT and T phone, but other than that would be the same for any carrier.

A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from your phone carrier to unlock your SIM card.

You can obtain your phone's PUK code from your carrier in one of these ways:

Log in to Your

Use a Technical Support Chat

Contact your carriers Customer Care

Get Your Phone's PUK Code Online

Go to the Phone/Device page.

From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading.

The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.

Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code.

Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator

Puk code

PUK- stands for PIN UNBLOCKING KEY.. well this happen only when u enter an invalid passcode when u enable a password protection for ur sim card. this is different when u miss entering codes on your phone lock. note: "sim locks", and "phone locks" are different from each other. sim locks only allows u 3 tries and after that a PUK will be required. while phone locks dont have any limit. so if thats the case.. ur only hope is the manual that comes with your sim cad. in there u can access for ur PUK and after entering that successfully u can now access ur sim card. but if not, u have to buy another sim card or change another number. but u can still use your phone.. -jepoyPH
