Well obviously the hotspot feature works. Ive used it many many times when I’m out in the hills. Ive also 3 note 10+’s. I’m using Tmo a dusting old SIM cards out of the old phones prior.
Do you have the 10+ , the 5G version or just the 10?
Can you link a source online that states its widespread or links to sources that show many people having the issue?
Is your phone unlocked or is it locked ? Did you purchase direct from the carrier or form Samsung? Did you use the same SIM card as your old device?
When you activate the hot spot feature, what does the screen tell you? Do you see the hotspot icon show up?
At the end of the day if other people on Verizon are having the issue, it may be something specific to the Verizon firmware , because on my 3 unlocked devices, its no issue.
Did you by chance do any backup/restore function and loaded an old software backup from your pixel?
