Name  Sapphire
Maker  GPT Marconi
Date late 90s
The Sapphire is a robust payphone of modular design which allows easy hardware module upgrades without the need for specialist tools. Low maintenance costs and ease of repair of the payphone are further advantages for the operator where the cost of an engineer visiting a payphone can be significant. These facilities reduce the cost of ownership of the payphone network, allowing the operator to improve the profitability of its payphone operations and to install payphones into a wider range of lower-traffic locations because of lower operating costs.
