Frequently asked questions

Which is better for digital nomads: Colombo or Koh Samui?
Koh Samui scores higher on the Freedom Score (69/100 against 68/100), which makes it the stronger all-round base. That is an average, though — if cost, climate or community is what actually decides it for you, the tables above will point the other way as often as not.

Which is safer: Colombo or Koh Samui?
Koh Samui scores higher on safety, 70/100 against 57/100. Safety scores blend crime levels, political stability and healthcare access, and they describe a city as a whole — individual neighbourhoods vary far more than the headline number suggests.
How fast is the internet in Colombo and Koh Samui?
Colombo averages 30 Mbps and Koh Samui averages 60 Mbps, so Koh Samui has the headroom if you push large files or run video calls all day.
What visa would I need for Colombo or Koh Samui?
Colombo sits in Sri Lanka (90-day+ stay) and Koh Samui in Thailand (DTV 5-year). Requirements, income floors and processing times change often, so check the visa and residency guide before you commit to either.
