If your phone uses a SIM card to operate, you can activate a security feature called a SIM PIN. The SIM PIN protects your SIM card from unauthorized use, and must be entered in order to use your phone. Enter it incorrectly three times and your SIM card becomes locked. You can unlock your SIM card on your own, however, by typing in a PIN unlock key. Your carrier can provide you with the unique PUK code for your device.
Step 1
Contact your wireless carrier by calling the toll-free customer service number. (Find this on your provider's website or a recent invoice.) You will need to verify your account password before the PUK code is released to you.
Step 1: Make a call to the 1503 from another BSNL mobile. Step 2: Listen to the IVRS system and choose the correct option to get the PUK. Step 3: When you select the PUK option then you will be connected to the executive. Step 4: Now ask them for PUK code for your mobile number. Step 5: Make answers to all of the customer care questions.
Step 2
Power your phone on. You will see a 'SIM Locked' or 'Enter PUK' message. Type in the eight-digit PUK code and press 'OK.'
Step 3
Type in a new four- to eight-digit PIN code when prompted, then press 'OK.'
Verify your new PIN code by re-entering it when prompted. Press 'OK.' Your SIM is now unlocked.
Warning
- If the PUK code has been entered incorrectly 10 times, your SIM card is permanently locked. You will need a replacement SIM card.
