I m facing same issues. Now no network since 24 hours. Changed sim from esim to sim. No network in this phone but all network in other phone. Some sim give 5g signal.like jio giving signal but airtel giving 0 signal

I am also facing same issue from yesterday. No network in airtel.sim, out of 2 jio sim, one worked 1 did not. Very strange. Changed e sim to sim and that also didnt work. Same sim working in all other phone. There is some issues after ui7 update
