No connection when switch from WiFi to 4G cellusr
I am using IPhone XS. When in my office I use Wifi. When I get out of my office my iPhone XS is unable to connect to my 4G network automatically. I tried to turn the mobile data on and off but does not help. The only solution is to restart the iPhone. This happens quite often. Is this a firmware issue or hardware issue?
iPhone XS, iOS 14
