Hi Wicksey,
I did say not to set a PIN when you got back into the phone. As this a "special" case this would be the best option .
Go to place were you can get a good provider signal.
Go through the procedure to get to the PUK screen.
When set PIN screen come up put in a PIN
Once in the phone go to Settings ->Security and remove # on Android 7 it's SIM card Lock settings
Power the phone off
Power the phone on and it will go directly in.
Hope you get it sorted.........

UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.
