Saba is the smallest island in the Dutch Caribbean and since 2010 is a special municipality of the Netherlands, but previously it was one of the islands that made up the Netherlands Antilles, a former nation constitutive of the Kingdom of the Netherlands. As in the other islands, even here the Landis & Gyr installed their public cardphones in 1987. With a population that at that time exceeded only a thousand inhabitants, it is not strange that the two cards supplied with the telephones, one of 60 units with code 709C, and one of 240 units and code 709H, had a circulation of only 500 copies each. These were also the only optical cards that circulated on the island, as new phones with chip technology were installed in 1996.
