I'll try this again without any "offensive" stuff;
Reset network settings, replaced sim card, tried data roaming on and off, tried just
using LTE, WIFI on and off, tried remote diagnostic with Apple, had diagnostic at
the Apple store, restored my phone to factory settings without any of my data
or apps to make sure something wasn't interfering, switched carriers, had the
phone replaced with a new one and went through everything again, and no luck.
The iPhone 13 pro Max does not work and I don't know how to point things out,
but Apple won't let me downgrade to another model or take mine back because I spent over the time limit trying to
get it to work. Their only suggestion was to try and sell it on my own and buy
something else.
