Soft reset your phone by removing the battery and the SIM card for one minute. Insert back the SIM card again and the battery.

PUK CODE SAMSUNG SGH-A167


phone does not have a puk code, the puk code is on the sim card, if you take the sim card out and put in any other sim card the phone will work, but if you put this sim card back in it will ask for a puk code again.


You can ONLY obtain the puk code from the service provider that the sim card is from, they are the only people who can get you your puk code, since its unique, programmed into the sim card, we can't calculate it or get it, its the service provider you HAVE to contact.

My samsung A437 reads insert sim card ans sos. The sim card is in there and we know it works since it can be used in other phones


Then I would try a Master Reset on the phone.

To accomplish that enter *2767*3855# as if you were entering a phone number. This will reset all settings to default, but leave all data untouched.

I need to unlock my puk code for samsung a437 phone


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.
