(Refurbished) Samsung Galaxy S21 Ultra

I'd like to start by saying i'm a Hurricane Helene survivor. I ordered this phone RIGHT before she hit here in northwest NC (Asheville), and wiped everything out including my job. After the disaster, wifi was a rare resource for a while, so I merely assumed that my phone's troubling inability to connect to service was temporary. When wifi returned, most cell towers were still knocked out and power was being restored all over the region, so it was no surprise that my phone was still unable to find a steady service connection. Slowly but surely as power was returned, other people were finding regular service. Not me! Oh no, I got to enjoy a frustrating rollercoaster of service disconnects, not receiving calls from my employer, missing important texts from people trying to check up on me and my father...these I only got to see when I restarted the phone after reconnecting to wifi. A trip to Charlotte was the teller when my phone never found service except for a few minutes after I rebooted it. Eventually, I could just manually reboot the sim card from settings and get the same 3mins of service experience before it would inevitably lose it. Well, silly little me just dismissed this cute little VOID sticker slapped at the bottom of the phone near the scuffed up charge port and sim card port -- ignore the shattered edges, this little treat happened the ONE time I dropped it in a BRAND NEW phone case. TBH the thing is so dang heavy I'm not surprised an Otterbox couldn't even save it from itself. But this sticker, man. I remember thinking "maybe it's voiding it as damage?" What a silly thought. They couldn't possibly sell me a broken phone! Pffffffffffffffff. Now I'm stuck with this ugly, broken brick, unable to afford a replacement because I'm on disaster financial aid and can't afford another meesely $350 device, and ATT absolutely REFUSES to let me buy a new sim card to test a desperate theory. I've been a long time customer of Samsung and you will not see me buying another; I'd rather be openly scammed by Apple, at least I know what to expect. Unfortunately, you can find articles dating back a couple years to this and the S22's release, discussing this exact issue with other providers. And can I just add that autocorrect is an embarrassing joke, like is it learning from 2yr olds, or just uneducated internet trolls because none of these words and capitalizations make any dang sense. TLDR; They might sell you a broken phone, and honestly it's kinda junk anyway.
