PLEASE PLEASE HELP!!! ACCOUNTANT DESPERATE TO FINISH HER CLIENTS CASE FILE - NEED TO ACCESS PUK Code to iPhone so I can log into my account

I have locked myself out of my SIM card some how on my iPhone SE 2nd Generation 2020.  I need my PUK Code so I can unlock my SIM card and use cellular data and receive text messages on my iPhone.  Unfortunately I currently can not receive iMessages because my I am also locked out of my AppleID (I have plans to go to the Apple Store tomorrow in person because I have been having issues for some time now and I believe my account is being compromised by someone else)

However, I am an Accountant and I need to finalize some client case files and I can not access my business email without doing "Two-Party Authorization" which I do with a text message off my cell phone!  I am sure you can now see my dilemma and I also use a "Two-Party Authorization" to log into my www.att.com account which, I already know I can obtain my PUK Code, myself by logging into my AT&T account and going under: "Account Overview/Manage Devices and Add-On's/Device Management and Troubleshooting (? I think?)/Device Options/Get PUK Code (or its somewhere in there because I have gotten myself before)"  HOWEVER, You do need to be able to have access to your account, and at the the time.  I had my husband here next to me with this cell phone, however he is out of town on a job site and YET Again here I am at 4am with another hurdle not able to use my iPhone or able to log into any of my business accounts because EVERYTHING I do is somehow tied to my iPhone and cell phone number.

SO PLEASE PLEASE HELP ME!  IT IS 4:00 AM AND I AM DESPERATE TO FIND SOMEONE AWAKE TO HELP!

Signed - By a Desperately Seeking Bean Counter with No Steam left for Coffee Beans at 4:00am and a Huge Steamer of "You Know What" that is going to hit the fan if I can not get into my business email and resubmit this document to my client before 9:00am this Thanksgiving holiday morning.

Sure hope someone in the support team at AT&T is awake and out there to help me or someone can drop off a bag, gloves and a mask for me because I have been working on this project with not sleep now for 48 hours!  Uugggg I need this one done and to get paid and get some sleep so I can eat Turkey in a few hours!

Thank you so very much for your assistance and hopefully for a some patience with my non-sleep and bad jokes :-)

Warmest Regards and In Your Services,

Theresa Clemons-Lum
