Simeulue is also called Mae o, which literally means 'Where are you going?'. Ethnologue also lists Long Bano, Simalur, Simeuloë, and Simulul as alternate names.

• Leukon: spoken in two villages in Alafan, namely Langi and Lafakha.^[4]
• Haloban: spoken in two villages in Banyak Islands, namely Haloban and Asantola.
