PUK code

    Yesterday, I decided to change the password on my phone and accidentally went into settings> phone> Sim PIN. then, entered a code three times and entirely locked my phone. This was quite idiotic of me. I couldn't take calls, send calls, messages, or receive texts either. So, I called AT&T and their horrible service. A representative answered and put me on hold five times, since he was looking up how to unlock it through a PUK code. I hate the annoying songs they play when they have you on hold- they go centuries back. Anyways, he gave me two twn digit codes; one for automatic PUK code messages, the other one for the error that occurs after going into a certain function that gets blocked.
 
    I had to press those numbers 10 times because there was an error message, stating the PUK was incorrect. Then, the AT&T guy referred me to an apple representative, and he got all pissed. "Why would they do that?" They had nothing to do with the SIM lock. It was such a hectic day, I thought I would completely have to buy a new phone, or SIM card, which is free, but wastes time when going to the store.

   Finally, I decide to write down the code that the 4th representative gave me and tried again. I remember inputting certain digits before I locked it and I tried to remember the combination. At last, I entered the PUK code, followed by the digits that locked the phone, and the issue was resolved. I had to go through all that, even though the issue was quite simple to resolve.

   This all happened because they forgot to mention that I had to redial the code I used when the phone got locked. That would have saved the 4 representative's time, and apple's grumpy attitude. Thanks for not telling me. Now I know not to ever so that again. Lesson learned.
