Ans: As soon as you insert a SIM Card in any Handset it asks for PIN (Personal Identification Number) which is a password that is known to the authorized user only. The PIN code can be set to protect your SIM card from unauthorized use. To prevent continuous attempts to ‘guess’ the PIN number the SIM card automatically gets locked-up after three consecutive wrong entries. If the SIM card is locked-up, the “Blocked” message will appear and an unlocking code will be needed. Further repeat wrong entries of PIN may lead to damage of card. The blocked SIM can be then opened through PUK number (PIN Unlocking code) which can be obtained from your service provider after establishing your identity. The PUK is an 8 digit code available with your cellular service provider. Also one should remember that 10 time’s successive wrong entries of PUK number may damage the SIM card forever.
