Forget pin code for adding a prepaid card - Samsung SCH-U450 Cell Phone

If your SIM card is PIN locked, the network unlock code is useless. The network unlock code allows a phone that is restricted to a single carrier to be unlocked for use in other carrier's networks.
The SIM PIN is a personal identification number that is used to unlock the SIM card in order to register it to the network. This means that the phone will not connect to the network before a SIM is unlocked. Usually (at least around here) a new SIM has a simple PIN, like 0000 or 1234, and the user can change this. However, the carrier doesn't know your PIN, so if you forget it it can't be reset from the carrier directly.
If you happen to forget your PIN, the only way to unlock the SIM is to enter a wrong PIN enough many times (3 or 5 usually), and after this the SIM asks for the PUK (Personal Unlock Key) code, which is sometimes referred to as PUK1.
The PUK code can be obtained from the carrier, after they verify you are the rightful owner of the SIM and contract. If the SIM is a prepaid, the PUK code is sometimes printed in the card holder. After you get the PUK, enter it into your phone and enter a new PIN. After this, you can unlock the SIM with the new PIN you specified.
Note: DO NOT try to guess the PUK code yourself, if you enter it wrong three times, the SIM will be permanently locked and you'll have to get a new SIM from your carrier.

Hi bundela_swat,

You can get the PUK code from your mobile network provider i.e Vodaphone by either calling them from another phone and verifying your identity or by going to the nearest customer service center of vodafone.

do not enter the wrong pin again and again that could cause your sim card to get blocked permanently.

Those features that you cant use are the access. Go to anything that requires xbox live in the main menu and press it. It should then give you a option to connect to xbox live. then you simply follow the on screen instructions and its done!

you should call the prepaid company if you did try taking the prepaid card out and put it in again

Hello,
This error has something to do with the incorrect attempts for the PIN entry. This happens when you entered invalid PIN 3 times.
The PUK code is the abbreviated term for Pin Unblock Key. If your account is prepaid, it is printed on a small paper bundled with the SIM card. If you are on post paid, the only way to obtain is by calling your carrier. They should be able to provide you the PUK.
Good luck!

hello:
the puk code you need are be giving by phone provider also the pin code for acces the sim card after 3 times rong code fhone card wil be blockt. ask you phone provider new codes they have if are prepaid card take new one mor cheeper

sir,
My aircel sim is blocked .
my no. 09807112718., sim no.,32K WIB 89918 10110 81306 23131.

pls send me my PUK CODE and pin no.

PUK means "personal unlocking key" .

The PUK code is asked if you enter a wrong pin 3 times.

You need to call the phone company that released the SIM card, they can retrieve the puk code from a database for free.

In your case you need to contact your SIM card provider technical support to unlock the SIM.


The PIN and PUK are related to the SIM card, not to the phone.

If you replace the SIM card with a different one, then the phone will not ask for the PUK anymore.

Hope This Helps!!! Please Don't Forget to Rate my Response!!! Thanks!!!
