This is my phone number. It is also a phone number. It is also a series of numbers. It is also ten numbers. It is also three groups of numbers. And it is also four spaces separated by numbers. But only when utilized as the first option will your voice be converted to an electrical signal and transmitted via radio waves to a nearby cell tower from which it will then be forwarded on in the same manner across as many cells as neccesary to deliver your call to me. Science, ftw.
