How do I unblock a blocked SIM card?

Answer by  mbc123 (80)

The best way to get the information from your blocked SIM card would be to have the password that you had gotten when you first purchased your phone, or call your phone service and explain your problem with them. They should be able to help you.

As i know, the sim card should come with the pin code which you can't use already, and the puk code which will help you to change your pin code. But if you block the both codes the only way out is to go to your operator.

Well this is quite tricky. You can't really do this yourself. You can't unblock the simcard if you are talking about unlocking it. Take it your local sim card provider and have them unlock it.

there are two ways, one call your wireless provider after your contract and see if they can be talked into unlocking it, and two "jailbreaking" it to make it useful on other networks. dont know how to off the top of my head but could look it up.

there is a PUK code on the back of mine that you can type in if it has any problems. If you dont have one, take it in for repair.

A blocked SIM, asks for PUK code. It is provided by the service provider. Enter the 8-digit PUK and your SIM is unblocked with default PIN provided by the service-provider.

In order to unblock a blocked SIM card, you must contact your service provider at the service center. They will give you a number, known as the PUK number. You can enter this number at the startup to unlock your sim. This service is free of charge with most service providers.

The best and the most effective way to unblock a SIM card that is blocked is to take it to the store from which you made the purchase and have them do it for you. The phone with the SIM card will still only work on the original network but it will work.

You cannot unblock a blocked SIM card yourself. You will need to bring the phone to the retail location of your wireless carrier and let them give you a new card. If it is asking you for a SIM PIN or a SIM PUK, you can call your carrier and they can give you the information.
