iPhone X Network issue with iPhone X

[sportykid2332]

Hey everyone. Been having a truly frustrating issue with my iPhone X (ATT). Multiple times per day, my service will completely drop out and basically cycle through states of full bars and no service. It will then usually stay at no service for as little as 5 min or as much as 1 hour. I had this issue shortly after launch but it eventually went away. It came back with the most recent iOS public beta update (11.2.5). I've tried resetting the network settings and even got a new SIM card from ATT. Would like to avoid doing a restore but I think that's my only option left. Would appreciate any help if someone else has resolved this issue! Can try to upload a screen capture video if helpful. Thanks!
