This problem occurs if you insert a SIM other than a SIM which you bought with the mobile. Eg. If you have bought a Samsung D840 from vodafone you can use vodafone network in it. If you want to use other networks you need to unlock it to the vodafone network. Unlocking can be done at www.mobile-unlocker.com .

I need puk code for lg gw525

These directions are for an AT and T phone, but other than that, are 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 account.online 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 for my t-mobil lg

Hi,

Improve the Fixya.com experience for everyone by voting!

Unfortunately, you have not provided the name of your carrier. However, the PUK process is almost universal and you should have no problem.

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 carrier. For example, if you have AT&T to unlock your SIM card, you can obtain your phone's PUK code from AT&T by:

? logging in to your my wireless Account online
? using their Technical Support Chat
? calling Customer Care at 1-800-331-0500

To get your phone's PUK code online from ATT:

? Log in to your my wireless Account.
? Select My Services under My Account.
? From the My Services screen, select My Phone/Device.
? Select Unblock SIM Card.
? The Unblock SIM screen will display your PUK code.


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 ATT 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."



I trust that this is helpful and solves your problem. All the best
