You don't appear to have any coverage issues at your home address that have currently been picked up.
To do a manual network search, you'll need to go into the device Settings.
It's usually found in Settings > Networks > More > Mobile Networks and then here you'll see Carrier or Network Operators.
You can tap this and turn off the automatic option to allow the phone to search. This will take a few minutes. Then let us know which results show, or select iD from the options.
If you're stuck, send us a screenshot of the Mobile Network settings.
