Sony
CM-H333

This was the first commercially available mobile phone from Sony. It was nicknamed the "Mars Bar" because of its size and weight. Released in 1992, it became one of the most desirable handsets of its time and was the first to come with a sliding earpiece that moved up and down to answer and end calls. It supported the analogue ETACS network. It had an address book that could only store three telephone numbers accessed via the one-touch dialling buttons A, B or C which were located at the bottom of the keypad.
