HI If you are asking for pin contact your service provider , he will give you a default pin .
If you try pin more than few
predefined no of times your phone will ask PUK code which can also be
given only by your service provider which is specific for each and
every mobile number . Do not try PUK(new pin code) code many times or else your sim
will be blocked and you will need a new sim.
Contact your sim customer care department over phone. Its free of cost to get the pin or puk no. Go to the nearest service outlet of your service provider they can also help you. There is no other go than the above procedure only your service provider can give it nobody else in this world nor any software.
try this :
This works on most mini electronic devices like cellular phones and degital cameras etc .
it sounds crazy .
Remove the back (or Cover ) of the phone( or Camera ), battery, and SIM if your phone ( or Device ) uses one , DIRECTLY
Then, with a q-tip (or something similar), dab the connection points (shiny, goldish) on the battery, SIM, and phone. This should aid in drying.
Finally, place all contents in a bag of uncooked rice (separately, do not put back together just yet). it sounds crazy , but it draws the moisture out.
It normally is working after just 7-8 hours, but I would wait 12 hours or even 24 hours before attempting to use (just to be sure).
beware the water damage, despite being dry now, will void any warranties. Also, the phone's hardware is now weakened and if you drop it, the green mother board and circuitry could shatter - so be more careful.
This does work on electronic devices aside from phones as well. Simply tailor it to your device. If you do not have a SIM (Verizon phones, cameras, all others), remove only the battery. If you have an iPhone/iPod or GPS and cannot remove the battery, simply make sure it is all the way off, then put it in the rice bag. All electronic devices react the same to the rice trick.
