Singapore Changi Airport- get a sim card called $15 version from 7-Eleven basement T1 rather than buying from exchange booths. You can get a Singtel sim and you can buy GBs as per your need.
One of the best designed co-working spaces I have visited in Singapore. Got lots of startups and great energy. Hot desks start fr $259 a month. Also there's a coffee shop under it. More of a startup scene than Digital nomads/freelancers.
Good co-working space with a good location and having a lots of options like team desk, private desks, meeting rooms, phone booths and you can rent mini offices. Nice co-working space for entrepreneurs and startups.
A great coworking space with great Internet and work conditions. People working on their startup and they have shared workspaces, private office, conference rooms, workshop areas, a coffee shop and what looked to be like a bar. Very helpful staff and nice atmosphere
