Nice kata! I recommend adding the example tests to the main test cases. My first solution passed the test cases on Attempt, while failing the example tests.

random string was 0P - i s G x u M l734661915
Expected: 'Not a phone number', instead got: '0734661915'

Not sure if Im missing something but I have 3 test cases which I'm sure should pass, or am I misisng something?

Thanks have done

C# translation Kumited, please review and approve.

Thanks so much for the feedback and for taking the time to try my kata!

I will have a look at that asap.

Perhaps some smarter random cases would be nice :)

You can always use a reference solution to check against user solution while you throw any number and kinds of arbitrary random cases to the user.
