Top 10 Phone Numbers for Your Trip to Koh Samui

A trip abroad is an adventure — but even in a country as safe and tourist-friendly as Thailand, things can occasionally go wrong. So you don't have to start googling in the middle of an emergency, we've put together only the numbers we could confirm on official pages run by authorities, hospitals and embassies. Anything we couldn't verify officially, we've deliberately left out.

Get a Thai SIM card or activate an eSIM as soon as you land — available at the airport, phone shops, and any 7-Eleven or Family Mart. With local data, WhatsApp, LINE and similar apps work reliably, and the emergency numbers below are free to call anyway, even without credit.

National emergency numbers

For most situations as a visitor, the Tourist Police (1155) is the best first call: they exist specifically to help foreign visitors, speak English, and pass you on to the right department if needed.

Hospitals on Koh Samui

Koh Samui has several private hospitals with a high standard of care. Travel health insurance is still an absolute must — see our article Top 10 Things to Avoid When Preparing for Your Koh Samui Trip for more.

Your embassy in Bangkok

For a genuinely serious problem — losing your passport, for example — contact your own country's embassy or consulate in Bangkok directly rather than a third party. Almost every nation maintains a diplomatic mission there, most within the Sathorn/Wireless Road embassy district.

The fastest reliable way to find your number: your own government's official foreign-travel-advice site (for example the UK's gov.uk/foreign-travel-advice, Australia's smartraveller.gov.au, or Canada's travel.gc.ca) publishes an up-to-date phone number and address for its Bangkok embassy or consulate under "contact us" or consular assistance — that's more reliable than a general web search, since numbers do change.

Frequently asked questions

What number do you call in an emergency on Koh Samui?

As a visitor, the Tourist Police on 1155 is usually the best first call, since English is spoken around the clock. For a medical emergency, call the ambulance service on 1669; for fire, call 199.
