How to enable ‘Port Check Test’ or ‘%2’ on your LG phone:
There are many different ways to enable this option, but not all of them will work on all phones. Try them out one-by-one

Dial in the following codes on your phone (without pressing call). If the code works a hidden menu will apear. Find the option ‘Port Check Test’, and set it to ‘Enabled’. It is usually in the top menu or in the ‘SVC Menu’ submenu.

In case you can not get to the hidden menu, or the hidden menu does not contain the option ‘Port Check Test’, try Factory Reset on the phone.
Diag port unavailable. Please set ‘Port Check Test’ to ‘Enable’
