At MWC this year, Samsung confirmed its plans to expand to 7 countries in 2016 beyond the two where it was already available (South Korea and the United States). Among those 7 countries, only China has seen the light of day so far, but it looks like Singapore isn't too far off. Samsung has just announced a partnership with one of Singapore's leading banks: Citibank.
The service, however, isn't yet fully launched in Singapore. Samsung's press release says its launch is slated for Q2 2016, but I'm not sure how that's possible given that Q2 ends in about a month and that Samsung seems to be just ready to start its beta test phase now. Select consumers who are also Citibank credit cardholders have been invited to enter their interest in participating in the trial and will be notified once the trial starts.
Regardless of the date, when it does launch eventually, Samsung Pay will be compatible with the Galaxy S7, S7 Edge, S6 Edge+, and Note 5 in Singapore. Other partners and banks haven't been announced yet.
