Jamaica, 1989

Compared to other Caribbean islands, Jamaica, although it is the most populated, began later to use the phone cards; however, numerous cards were issued, even in large quantities. The cards were supplied by GPT, and before the official issues a public experimentation was carried out with the Albert Dock standards that the English Company often provided when the telephone sets were installed. There are four values: 10u (1JAMA code, 1,000 issued), 50u (1JAMB, 1,500), 100u (1JAMC, 2,000), and 500u (1JAMD, 1,000).
