My s22+ did the same after ui 6 update. After a new SD card and a week later, still same problem (not registered on network). It was 100% on ATT’s end not Samsung, as ATT tried to state. 1.5 hrs later on the phone with an ATT tech, he finally fixed it. Start off by saying you already put a new SD card in to save a week of troubles. DO NOT reset network settings or factory reset, neither of these options worked. Hope this helps y’all some troubles
