The first caps for Samin in the Tahitian squad were in 2000. He has since taken part in four FIFA World Cup qualification tournaments, and was a major part of the Tahitian title of the 2012 OFC Nations Cup. Starting the competition as a backup goalkeeper to Mickaël Roche, Samin was promoted to a starting position in the third match, a 4–1 win against Vanuatu. He was also the starting goalkeeper for the next two matches, keeping a clean sheet in the semifinal match against Solomon Islands and in the final against New Caledonia, both won by 1–0. His long experience with the "To'a Aitos" made defensive midfielder Lorenzo Tehau declare that "I’ve played with Samin since I was a kid. He’s like my dad."
