For the uninitiated, the prophets regex pattern used here is a simple yet
elitist way of checking if a phone number is valid or not. It looks for either a
10-digit number or a 11-digit number with the + symbol in front of it, because
that is just the kind of sophistication one would expect from a refined individual.
