"No Service":

Go here to fix that: If you See No Service or Searching on your iPhone or iPad - Apple Support

Do you have cellular service? Is your phone registered with your cellular provider?

my cellular data screen is blank. Phone has no service. I can't make any calls or text. Any ideas on how to fix this issue. iPhone 8 updated to iOS 15.1, no carrier issue according to T mobile.
