"In the beginning was the word, and the word was two bytes..."
It's scary to imagine today, but once upon a time in ancient times, SIM cards did not exist at all. The mobile phone number was firmly tied to the device and there was no greater grief for the user than the loss or upgrade of a favorite phone.
