The C902 can't be unlocked via code or free software. However, if you look around your local area, you may be able to find a phone unlocking service. They've got the right equipment to unlock your phone, and isn't very expensive.

My sim is requesting me for my sim network pin..i dont know what to do please help me mr adeem.. :(


If your phone is asking for a "Network" pin it means your handset is locked onto a different network to that of your SIM card.
If this is the case, then you need to:
A) Get the handset "Unlocked"
B) Get a SIM card, relevant to the handsets carrier.
If the handset is simply asking for a PIN it may just be your SIM card PIN it requires.
If you didn't set a PIN on your SIM card the usual default pins are:
0000
1111
1234
5555
Unless you have a Wave SIM and that is different for every SIM
If you enter the PIN incorrectly after usually 3 attempts your SIM is blocked and you will need a PUK code to unlock it.
PUK codes can only be given by the SIM cards carrier (Service Provider) this means that you will have to call them and ask for it.
You will need either the SIM Card number (On the front of the SIM) or the SIMS mobile number.

Sim network unlock pin


The phone will ask for "Sim network unlock pin" when you try other network Sim card on a carrier locked phone. To unlock the carrier lock of Sony Ericsson Xperia X10 you can use unlock code. You can get the unlock code from MobileUnlockSolutions.com . There you have to give your Country and current network name along with your IMEI number to get the unlock code. Enter the unlock code when the phone asks for "Sim network unlock pin" to unlock it.

Hi i have a new phone and i tried to put a code in now its asking for a puk number


Hello, Your mobile phone's sim card has a four-digit PIN code enabled by default. If you enter the PIN code incorrectly three times, a lock will be put onto the SIM card, and you need a PUK code to unlock it. If you're being asked to enter a PUK, you will need to contact your network operator to get your sim card unlocked. This is for security reasons. Note that only your mobile phone network operator can legally provide you with a PUK code to unlock your SIM card. Thank you for using Fixya

I need a puk code for my LG Neon


One way is by going to your AT&T and tell them to unlock your LG Neon and when they do ask them if they can reset it so you wont have any more problems with the PUK code.

Bought nokia n95 phone without sim card in ,but now i,ve put sim card in phone shows good signal but won;t let me phone out


  • PUK means "personal unlocking key" .
    The PUK code is asked if you enter a wrong pin 3 times.
    You need to call your phone service company, they can retrieve the puk code from a database
    for free.
    In your case you need to contact your SIM card phone 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 should not ask for the PUK anymore.
    Your rating is highly appreciated on this matter.
