My net 10 sim is blocked how do i un block it

contact your network service provider or take your puk code form SIM jacket or packet

PUK code is a SIM specific code assigned by your service provider so call Customer care and state the problem then they will ask for some codes written on you SIM card. Few people use PIN locking system to lock their phone to avoid un-authorised access. Though this is a good option, it ****** you off sometime. Three wrong entry of PIN code will result in SIM blocking. Once SIM gets blocked, phone starts asking PUK code to enter. If you again enter wrong code for three times, SIM gets completely blocked. You have to walk into your service provider outlet to get a replacement SIM card.
I think it may help you.

A PUK blocked message pops up after one enters the wrong PUK code 7 or 10 times in a row, depending on the service provider. A PUK code is required only after one blocks the SIM PIN code.

Many times, it may so happen that you block your PIN code. You will need to call the customer care of the service provider of your cell phone for the PUK code or refer the SIM certificates for the PUK code. If you enter the wrong PUK code 7 to 10 times in succession, it will lead to PUK blocked. After entering the wrong PUK code 10 times in a row, the SIM card becomes permanently invalid or locked. The only solution is to purchase a new SIM card.

PUK blocked requires you to get a new SIM card. It does not matter whether you use a Nokia Cell Phone, LG Cellphone, Motorola Cell Phone, Samsung or Sony Ericsson handset. The handset is not the one that's deactivated, but its the SIM card that gets blocked. So, contact your network store for further help and getting yourself a new SIM card (new phone number).

Hello,

A sim block usually indicates that your wireless provider has put a block on your account. There are also certain applications associated with wireless phones in which a user can set up their phone and lock it remotely, or block many of the features accessible on it.

I would start with your wireless network carrier. Ask them why the SIM card is blocked.

Your PUK code is blocked because you have entered wrong code more than 10 times and now you have to replace your sim card. This sim will not work now. Contact your network provider, they will issue you a new sim card.

SIM cards can only be unblocked by the Service Provider (cingular, t-mobile, etc). They have a specific code based on the SIM card number. If you have entered the incorrect code more that 5 times, you will invariably incapacitate the SIM card. Contact your providers support department, or go to the store and they should be able to take care of it for you. Best of Luck.
