Connectivity
SIM / eSIM Availability
eSIM and physical SIM cards are available in Thailand. eSIM is the most convenient option for travelers with compatible phones.
Internet Speeds
Typical speeds: 30-100 Mbps average
Recommended eSIM Providers
Airalo, Holafly, AIS, DTAC, TrueMove
Money & Costs
Average Hotel Prices
$30-150 per night Book on Expedia
Typical Daily Budget
$50-150 (mid-range traveler)
ATM & Cash
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.
Card Acceptance
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.
Transportation
Major Airports
BKK, DMK, HKT (serving Bangkok, Phuket, Chiang Mai)
Car Rental
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.
Public Transport
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.
Safety Overview
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.
Things to Watch For
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
- βTemple-appropriate clothing
Cover shoulders and knees for temples - pack long pants/skirt and a shirt with sleeves, or buy locally for cheap
- βStrong mosquito repellent (DEET-based)
Dengue fever and other mosquito-borne diseases exist - protect yourself especially at dawn/dusk
- βReef-safe sunscreen
Thai sun is intense and several marine parks ban non-reef-safe sunscreen
- βCash in small bills (100 and 500 THB)
Street vendors can't break large bills - get small denominations at the airport or bank
- βLightweight rain jacket or poncho
Monsoon season (May-October) brings sudden heavy downpours - compact rain gear is essential
- βUniversal power adapter
Thai outlets accept multiple plug types (A, B, C, O) but a universal adapter ensures compatibility
- βPortable fan or cooling towel
Thailand is hot and humid year-round - small cooling aids make temple visits more comfortable
- βAnti-diarrhea medication
Traveler's stomach affects many visitors - having Imodium ready saves scrambling for a pharmacy

Frequently Asked Questions: Thailand
Do I need a plug adapter for Thailand?
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?
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?
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?
Thailand uses the Thai Baht (ΰΈΏ). 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?
Thailand uses 230V at 50Hz. US devices (120V) may need a voltage converter for older appliances. Most modern electronics with dual-voltage chargers (100-240V) work fine with just a plug adapter.
Do US devices work in Thailand?
US two-prong plugs typically fit Thai Type A outlets. Grounded three-prong plugs need an adapter. For voltage, check your device - modern electronics handle 100-240V. Hair dryers and similar may need a converter.
What is the emergency number in Thailand?
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?
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?
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.
