Traditional telephones are powered by the local telephone exchange and do not need to be connected to a mains supply. Modern telephones often use a separate supply to power the additional features of telephones such as memory diallers, number displays, wireless handsets and so on.

You can but you would need a sim card reader connected to your computer.
