It really should "just work."
I am beginning to suspect it's a carrier/service issue. Maybe purchase one additional SIM for a few bucks, along with the cheapest plan you can find (for a few more) and use that to try a different carrier.
I could tell you who I use but it may be irrelevant in your area.
Other than that, I would not be messing with modem codes and stuff at the command line. I never needed to do any of that. If you have a spare sd card (or don't mind wiping current one) flash a clean, new OS image (of Mobian) and just let it do its thing.[0]
Other than that, maybe make sure the sd card is actually good. How old is it? Is it a good brand name card from reliable vendor (which DO NOT include Amazon and eBay nowadays)? There are some software tools you can use to verify the card itself before writing your image to it. Basic stuff but actually quite common problem.
Only update your OS at the command line (for now). The GUI Software Center (or whatever it's called) is not fully reliable just yet. Just making sure we have covered all basic things here.
[0] I can't help but wonder if something was borked with all the fiddling; this would eliminate that possibility.
