Thailand Travel Guide: Money, eSIM & Culture

Yes. As of April 2026, 1 USD ≈ 36 THB, which keeps Thailand among the best value destinations in Asia. A mid-range traveler can live comfortably on $40–$80 per day including 3-star hotels, restaurant meals, and local transport. Backpackers can stretch to $25–$40 per day. Bangkok and Phuket are the most expensive cities; Chiang Mai, Isaan, and smaller islands are meaningfully cheaper.

The best rates are at SuperRich, Value Plus, and X-One exchange booths in Bangkok — typically 2–4% better than airport kiosks and 5–8% better than hotels. At Suvarnabhumi airport, change only what you need for a taxi (roughly 500 THB). Bring clean, unmarked bills. For larger amounts, Wise or OFX can transfer at mid-market rates directly into a Thai bank account.

You need cash. Cards work at hotels, malls, upscale restaurants, and 7-Eleven (above ~100 THB), but street food, tuk-tuks, taxis, songthaews, markets, and most temples are cash-only. Carry 500–1,000 THB in small notes daily. ATMs charge a 220 THB foreign-card fee, so withdraw in larger amounts less often. Always choose to be charged in THB, not your home currency.

An eSIM is a digital SIM profile you install on your phone (no physical card) that gives you mobile data on a local network. For Thailand, an eSIM from Airalo, Holafly, or the Thai carriers AIS and dtac costs $5–$15 for 7–15 days of 4G/5G data — significantly cheaper than roaming with most US/UK carriers. Activate before you fly; you'll have data the moment you land. Your phone must be eSIM-compatible (iPhone XS and newer; most Pixel and Samsung flagships from 2020+).

Yes, as of 2026. Passport holders from the US, UK, EU, Canada, Australia, and New Zealand receive a 60-day visa-free entry stamp on arrival (extended from 30 days in July 2024). It can be extended once by 30 days at an immigration office for 1,900 THB. Your passport must have at least 6 months validity and one blank page.

November to February is the cool dry season and the peak window — 25–30°C in Bangkok, low humidity, minimal rain. March to May is the hot season (up to 40°C). June to October is the rainy season, when rooms are cheapest and the Gulf islands (Koh Samui, Koh Pha Ngan) actually stay drier than the Andaman coast (Phuket, Krabi).

At Rajadamnern Stadium, tickets range from 1,000 THB (third class) to 2,500 THB (ringside). At Lumpinee Stadium, expect 1,500–2,500 THB. Fight nights are typically Tuesdays, Thursdays, and Sundays. Buy at the stadium box office on the day to avoid tout markups of 30–50%. Eight fights per night; main event usually around 9:30pm.

No. Tap water in Thailand is not considered safe for foreign visitors. Drink bottled water (7 THB everywhere) or use a filter bottle. Ice at restaurants and hotels is generally safe — it's made commercially from filtered water in standardized cylindrical or tube shapes. Avoid loose, irregular ice from street vendors.

Tipping is not customary. Rounding up a restaurant bill or leaving loose coins is normal. 20–50 THB for housekeeping, porters, or a spa therapist is appreciated but not expected. Higher-end restaurants often already include a 10% service charge, so check the bill first.

Yes. Services like Wise, OFX, Instarem, and Remitly let you send THB abroad or send USD/GBP/EUR into a Thai bank account at near mid-market rates — typically 3–5% cheaper than bank wire transfers. For real-time comparison of fees and exchange rates, see our USA→Thailand, UK→Thailand, and Australia→Thailand corridor pages.

Thailand uses plug types A (two flat pins), B (two flat pins plus grounding), and C (two round pins). Voltage is 220V at 50Hz. Most modern US, UK, and EU phone chargers and laptops are dual-voltage (check for '100–240V' on the adapter), so you only need a physical plug adapter, not a voltage converter. Hairdryers and hair straighteners from the US (120V-only) will burn out.

Broadly yes — Thailand ranks as one of the safer Southeast Asian destinations for solo female travelers. Standard precautions apply: dress modestly at temples and in rural areas, be cautious with drinks on the islands (particularly Koh Pha Ngan during Full Moon Party season), and stick to licensed taxis or Grab/Bolt after dark. The deep south (Pattani, Yala, Narathiwat) is not recommended due to ongoing insurgency and has Western travel advisories.
