I was playing around with my phone settings and accidentally locked my SIM. I went into general settings/phone/lock sim and entered a 4-digit code (my personal made-up code) and my SIM locked. It says "SIM Locked" on the top left in the status bar where it usually says Verizon, and when I enter in the code it says incorrect. The option to turn it off in setting sis now grayed out. Any ideas? A google leads me to unlock on myverizon, but I only have to option to show my codes, which says "unknown" for both the SIm code and PUK.
