Invalid number. Please upgrade to a paid plan to use imaginary, non-real, or non-numeric numbers.
I had made a silly, silly mistake when I went to restrict numbers longer than 7 digits from the "free plan", I had at the same time disallowed digits larger than 7 as being "valid digits", so anything with an 8 or a 9 had been "invalid".
