He made his debut for the Dutch side on 16 June 1995 in a friendly match against Ireland. Since then the defender has played 201 international matches for Holland, in which he scored 140 goals. Lomans was famous for his penalty corners. He is one of the precursors of the drag flick technique that appeared in the 1990s.
Just before the 2004 Summer Olympics in Athens he was removed from the team by coach Terry Walsh. Lomans played in the Dutch League for Push and HGC, and stopped at top level in the spring of 2005. He made a comeback for the 2006/07 season in the Dutch League and scored more than 20 goals once again. He was renamed in the national team in June 2007.
In 2014, Lomans, now living in Singapore, reignited his career with the Singapore Dutch, and helped the side seal gold with a 5-0 victory over Hong Kong in the final of the ZOAT at HKFC's Sports Road ground.
Following the disappointment of the 2015 ZOAT, in which the Singapore Dutch finished 9th in Bangkok despite only conceding one goal the entire tournament, Lomans was determined to make amends at the annual 2016 SCC sixes tournament at The Padang. The Dutch came agonizingly close to a coveted place in the finals but eventually fell to local rivals SRC in the semi-finals, 2-0. As a small measure of consolation Lomans was however, named player of the tournament, beating out team-mate Paul Rombeek, who lost out on points for his raucous behaviour on the dance floor..
