Blocked SIM card and getting asked for PUK on Lineage OS 17.1 I installed Lineage OS 17.1 on my Samsung Galaxy S3. Everything worked just fine until I put in my SIM card. The first thing which happened after booting was getting directly asked for the PUK code although I didn't even enter a PIN at all. So I just rebooted the phone again which made it not recognize the SIM card anymore.
After that, I put my SIM card in my Samsung Galaxy S5 with stock ROM and I got the message that my SIM card is permanently blocked.
Any idea what happened there?
You have SIM password. You enter wrong password. Then it ask for PUK code. PUK code is link with sim card.
Use sim on normal mobile. Is it ask PUK code.
You can get PUK code from customer care. You can also get it from your online register account.
Get PUK code and use it. Weather sim card work after it.
