Guys, if you’re a BSNL customer and if you’re facing problems to get the PUK code for BSNL, then this post is for you. The reason why you’re facing this issue is that you’ve lost your personal identification number. To reset the forgotten PIN, you’ll need to reset the PUK. Personal unblock code helps you to reset the PIN code.

These codes are 4 to 8 characters in length and are forgettable (if you don’t use them often). Thus, it’s always a good idea to not use them. If you don’t remember the phone’s/tablets PIN or PUK, then your mobile is bound to be locked as you’ll keep on entering invalid numbers.

If your subscriber identity module card has been locked, then follow any of the below tutorials to get the code –

Tutorial 1:

Call the BSNL customer care. When you call them, the executive will ask you to mention the SIM number. Well, if you don’t know your BSNL SIM number, first note it down from the back of your SIM card and then call the customer care. Verification is necessary because you’ll have to prove that you’re the owner of the card. If your phone has been lost and you don’t know the SIM number, then you’ll not get the code because the customer care will not be able to verify your ownership.

The support guys are helpful. They should solve your problem. If you don’t get PUK for BSNL through this method, please follow the next tutorial.
