Island life rewards doing things in the right order. Sort the arrival admin, get connected, set up transport safely, open a bank account before the rules tighten further, and pick your area before you sign a year. Here is a phased, week-by-week checklist tuned to Samui — from before you fly to settling into the community.
You do not need to do everything at once. Spread it across five phases — before you fly, your first few days, then weeks one, two and three-to-four — and each step sets up the next. The island twists on a few of these (checking the actual fibre line, riding safely, the limited songthaew network), so we have flagged those specifically.
Sort your visa pathway and confirm current rules with Thai Immigration; complete the TDAC (digital arrival card) close to departure; book a flexible first month of accommodation rather than a long lease sight-unseen (budget from around ฿8,000–18,000 a month once you settle into a 1-bed); copy passport, insurance and key documents to the cloud; line up travel/health insurance from day one. Verify visa specifics with the official source — this is not legal advice. Grab our free checklist and skim the visa overview.
Get a Thai SIM at the airport or a phone shop for data and maps. Make sure your accommodation completes the TM30 address registration (hotels and many landlords do this for you — confirm it is done). Get cash, find your nearest ATMs, and locate the closest hospital ER and pharmacy to where you are staying. Use songthaews and Grab while you settle — do not rush into renting a scooter on day one.
Choose your area (use our neighbourhoods guide) and start viewing rentals — but before any long lease, test the actual fibre line in the unit and check recent electricity bills, the two things newcomers most often get burned on. Sort transport safely: a scooter runs about ฿2,500–3,500 a month — if you rent one, photograph it, keep your passport (a photocopy is the deposit), wear a proper helmet and carry the right licence and insurance; consider a car if you have kids — see getting around.
Open a Thai bank account if your visa allows — note that banks have tightened requirements through 2026, so bring your passport, visa, proof of address (a lease or a letter) and patience; some branches are easier than others. Register with Bangkok Hospital Samui (or your chosen hospital) and confirm your insurance works there. Sign your lease once the connectivity and bills check out, and set up utilities and home internet.
Settle in. Diarise your 90-day report (the first falls ~90 days after arrival) and keep on top of visa admin — verify dates with Thai Immigration, not advice. Plug into the community: the "Koh Samui Digital Nomads" and general expat Facebook groups, Startup Samui meetups, and the island's strong wellness / yoga scene are the fastest ways to make friends. Find your coworking spot if you work remotely (nomad guide), your regular markets, and your routine.
Every newcomer to Thailand hits the same three: the TDAC digital arrival card (done around the time you fly), the TM30 address registration (your hotel or landlord usually files it — just confirm it happened), and the 90-day report (a periodic notification of your address to Immigration, the first due roughly 90 days in). None are hard, but missing them causes friction later. Keep digital and paper copies of everything, and treat the official Thai Immigration channels and our free checklist as your reference — this is general information, not legal advice.
| Task | When | Who does it |
|---|---|---|
| TDAC (arrival card) | Just before / on arrival | You, online |
| TM30 (address registration) | On arrival at your address | Hotel / landlord (confirm) |
| 90-day report | ~Every 90 days | You (online, in person or by post) |
Check the fibre before a long lease. Internet is fast in Chaweng, Lamai, Bophut and Maenam but patchier in the remote west and hills — test the actual line in the unit and keep a mobile-data backup before committing for a year. Set up transport safely. Samui's roads carry a serious accident toll; if you ride a scooter, helmet, correct licence and insurance are non-negotiable, and a car is the safer call for families. Visa and banking rules are tightening in 2026 — verify current requirements with the official source; this is not legal or financial advice.
Work through the phases with the Samui planner and free checklist beside you, and lean on the cost guide, area guide and transport guide as you go. Get the order right and a daunting move becomes a calm month.
Before you fly, confirm your visa pathway with Thai Immigration, complete the TDAC arrival card and book a flexible first month rather than a long lease sight-unseen. In your first days, get a Thai SIM, make sure your accommodation files the TM30 address registration, find your nearest ATMs and hospital, and use songthaews or Grab while you settle before renting a scooter.
Yes — they apply across Thailand. The TM30 registers your address and is usually filed by your hotel or landlord (confirm it is done). The 90-day report is a periodic notification of your address to Immigration, with the first due roughly 90 days after arrival. Keep copies of everything and verify current requirements with Thai Immigration; this is general information, not legal advice.
Often yes, if your visa allows, but banks have tightened requirements through 2026. Bring your passport, visa, proof of address such as a lease or a letter, and patience — some branches are more flexible than others, and a longer-term visa helps. It is worth doing in your second week once you have an address. Confirm current rules directly with the bank; this is not financial advice.
Yes. Book a flexible first month, then choose your area and view rentals in person. Crucially, before any long lease, test the actual fibre internet line in the unit and check recent electricity bills — the two things newcomers most often get caught out by. Renting short-term first also lets you feel out the island's areas before committing for a year.
The fastest routes are the island's Facebook groups (such as 'Koh Samui Digital Nomads' and general expat groups), Startup Samui meetups, the coworking spaces, and Samui's strong wellness and yoga community. Pick a regular market, a coworking spot or class, and a routine. Most people feel meaningfully settled within the first month if they plug into these early.
With a phased plan, about a month. Arrival admin and a SIM take the first few days; choosing an area, setting up transport and viewing rentals fill week one; banking and registering with a hospital come in week two; and weeks three to four are for signing a lease, the 90-day-report diary entry and plugging into the community. Doing it in order is what keeps it calm.
