"No Service":

"No Service" is shown on the top left-corner of your screen. So here to fix that: If you See No Service or Searching on your iPhone or iPad - Apple Support


Charge your Battery:

An extremely-low battery is shown on the top-right corer of your screenshot. So, charge it.

Call Apple Support:

The CPU in there has become a bit loose. Having researched this for a bit, you'd have to take it apart, remove the battery, clean off the CPU. It's a bit technical process. So, have Apple replace whatever need be.

Apple Contact Info:

Why the Wait:

Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)
