The packing box is the best and easiest place to look for the PUK code to unlock your SIM card.
You probably have memories of the flat plastic package you got when you bought a SIM card. Your PUK and default SIM pin code should be written on the package.
Please look around your home for the package and look on the back for the key. On some older packaging, it could be sealed behind a scratchable region, whereas on other, more recent ones, you might find it unsealed.
In either case, the correct PUK has 8 numbers and should be simple to enter to unlock your SIM card.
In all honesty, I doubt I'll ever be able to locate my SIM card package again, and I imagine most people feel the same way.
But happily, a lot of cell companies let you access your account on their app or website to check your SIM card PUK. Please log in to the appropriate website or app, then go to your profile to see whether anything about "PUK" is available there.
It shouldn't be an issue if you were utilizing or signed in to the platform before your SIM was disabled. However, if not, you might not be able to access anything since you could be asked to input an OTP to verify your identity.
Please remove the SIM card and try again if you can't access your phone to utilize the app or website because of the SIM lock. After receiving the PUK code, you can re-insert the SIM and input it.
It's time to call customer support, which should be simpler for most individuals if none of the above options work for you. For example, your mobile service provider created your SIM card. Therefore, they have all the information you would require. Before they divulge anything to you, though, they should be able to verify your identity.
Use a different phone to call your customer service number and describe the issue. And following a series of inquiries, they should offer your PUK number as identification.
However, customer service won't release the code if you can't back yourself up. And at that point, there's probably nothing further you can do. Therefore, make sure you have some information, such as your name, address, date of birth, etc., before you call them.
