What Thailand runs on the wall — and whether your charger speaks the same language.
Mobile data, WiFi, the works.
The practical bits about getting online — eSIM availability, typical speeds, and recommended providers.

30-100 Mbps average
Airalo, Holafly, AIS, DTAC, TrueMove
Skip the airport SIM queue.
Activate a Saily or Airalo eSIM before you fly — data the moment you land in Thailand, no SIM swapping needed.
What it costs, and how to pay.
Hotel prices, daily budget, ATM realities, and whether your card actually works at the noodle counter.
$30-150 per night.
$50-150 (mid-range traveler)
ATMs charge 220 THB (~$6) per withdrawal for foreign cards - no way around this. Withdraw larger amounts to minimize fees. Bangkok Bank and Kasikorn are reliable. Currency exchange booths in malls often offer better rates than airports.
Cards accepted in hotels, malls, and upscale restaurants. Cash essential for street food, local restaurants, markets, taxis, and most daily purchases. 7-Eleven accepts cards for purchases over 300 THB.
Airports, rentals, and rails.
How to actually move around — from arrivals to the city, and from the city to the next one.
BKK, DMK, HKT (serving Bangkok, Phuket, Chiang Mai)
Available but challenging - Thai traffic is aggressive and follows local logic. Motorbike rental is common but accident rates are high. Thailand drives on the left. International Driving Permit technically required.
Bangkok has excellent BTS Skytrain and MRT metro systems with English signage. Grab (Southeast Asian Uber) works well for taxis and motorbikes. Outside Bangkok, songthaews (shared trucks), buses, and domestic flights connect cities.
Skip the arrivals scramble.
Pre-book a Welcome Pickups transfer for a stress-free arrival in Thailand, or compare car rental deals if you're road-tripping.
What to watch for, and what's overblown.
An honest read on travel risk — without the embassy-website doom or the Instagram glow.
Thailand is generally safe but scams target tourists regularly. Common ones include gem shops (fake stones), jet ski damage claims, tuk-tuk tours that end at commission shops, and overly friendly strangers with too-good deals. Drink spiking occurs - watch your drinks. Avoid political gatherings.
Respect the monarchy - lèse-majesté laws carry serious penalties (up to 15 years). Don't disparage the royal family in any way. Common scams: fake gems, jet ski damage, drugged drinks. Monsoon flooding affects some areas.
What to pack for Thailand.
Country-specific items, not a generic checklist. Curated for Thailand's particular quirks.
- 01Temple-appropriate clothing
Cover shoulders and knees for temples - pack long pants/skirt and a shirt with sleeves, or buy locally for cheap
- 02Strong mosquito repellent (DEET-based)
Dengue fever and other mosquito-borne diseases exist - protect yourself especially at dawn/dusk
- 03Reef-safe sunscreen
Thai sun is intense and several marine parks ban non-reef-safe sunscreen
- 04Cash in small bills (100 and 500 THB)
Street vendors can't break large bills - get small denominations at the airport or bank
- 05Lightweight rain jacket or poncho
Monsoon season (May-October) brings sudden heavy downpours - compact rain gear is essential
- 06Universal power adapter
Thai outlets accept multiple plug types (A, B, C, O) but a universal adapter ensures compatibility
- 07Portable fan or cooling towel
Thailand is hot and humid year-round - small cooling aids make temple visits more comfortable
- 08Anti-diarrhea medication
Traveler's stomach affects many visitors - having Imodium ready saves scrambling for a pharmacy

Open ↗The questions readers actually ask.
Eight questions our readers send the most. Answered without hand-waving.
Do I need a plug adapter for Thailand?Open
Thailand uses multiple plug types (A, B, C, and the unique Type O). US two-prong plugs usually fit Thai outlets. However, a universal adapter is recommended for reliability, especially with grounded three-prong plugs.
Is tap water safe to drink in Thailand?Open
No, tap water in Thailand is not safe to drink. Drink bottled water only - it's cheap and available everywhere. Ice in tourist restaurants is usually made from purified water and is safe. Street food ice may be less reliable.
Is travel insurance required for Thailand?Open
Travel insurance is not required but strongly recommended. Thai hospitals are excellent but private hospital costs are significant. Insurance should cover medical evacuation, adventure activities, and motorbike use if planned.
What currency is used in Thailand?Open
Thailand uses the Thai Baht (฿). Cash is king for daily expenses. ATM fees of 220 THB per withdrawal are unavoidable for foreign cards. Currency exchange in malls and downtown areas offers better rates than airports.
What voltage is used in Thailand?Open
Thailand uses 230V at 50Hz. Dual-voltage electronics (100-240V) work fine with just a plug adapter. If you're from a 100-127V country (US, Canada, Japan, etc.), single-voltage appliances must NOT be plugged in — they will receive nearly double their rated voltage and can overheat, catch fire, or be destroyed. Hair dryers are almost always single-voltage — check every device label.
Do US devices work in Thailand?Open
US two-prong plugs typically fit Thai Type A outlets. Grounded three-prong plugs need an adapter. Thailand uses 230V (vs US 120V), so single-voltage US appliances like hair dryers must NOT be plugged in — they can overheat or catch fire. Dual-voltage electronics (100-240V) work fine.
What is the emergency number in Thailand?Open
Tourist Police: 1155 (English available). General Emergency: 191. Ambulance: 1669. The Tourist Police are specifically trained to help visitors with everything from crime to disputes.
What language is spoken in Thailand?Open
Thai is the official language. English is spoken in tourist areas, hotels, and by younger Thais, but limited elsewhere. Learning 'Sawadee' (hello), 'Khop khun' (thank you), and 'Mai pen rai' (no worries) goes far.
Do I need a visa for Thailand?Open
Most Western countries get 30-60 day visa-free entry. US, UK, and EU citizens get 30 days (or 60 at airports since 2024). Extendable at immigration offices. 'Visa runs' to neighboring countries are scrutinized.
