You won't believe these 10 facts about people. A dial tone is the signal that a person hears on a landline telephone before he dials a phone number. In most instances, the signal disappears once the first number is dialed. In most cases, cell phones do not have a dial tone.
Another theory is based on the layout of a rotary telephone. On a rotary dial, 1 is at the top right and zero is on the bottom. When designed the new touch-tone keypad, putting the 1 on the top-right didn't make much sense, because Western writing is read from left to right. But putting 1 on the top-left, and the subsequent numbers to the right, did make sense.
