Here is the honest version most roundups won't give you: Cambodia, Thailand, and Vietnam are not three flavors of the same thing. They separate on one axis more than any other — how you legally stay long and how reliable the day-to-day infrastructure is — and they land in three genuinely different places. In one line:
- Thailand is the best long-stay base if you can show savings, thanks to the DTV visa and the region's best hospitals — but it costs the most and asks for paperwork up front.
- Vietnam is the value winner with fast internet and a strong beach-town scene in Da Nang — as long as you accept quarterly visa runs, because you cannot extend a Vietnam e-visa from inside the country.
- Cambodia is the easiest to walk into and one of the cheapest, but its fixed internet is roughly a quarter the speed of the others, healthcare is thin, and the once-famous "stay forever on a business visa" route is tightening fast.
Pick by your constraint: savings and health priority push you to Thailand; budget and internet push you to Vietnam; ease of entry and low burn push you to Cambodia.
The three at a glance
| What matters | Cambodia (Phnom Penh) | Thailand (Chiang Mai / Bangkok) | Vietnam (Da Nang / HCMC) |
|---|---|---|---|
| Solo monthly budget, all-in | $800–1,400 | $1,200–2,500 | $700–1,300 |
| One-bed rent, decent area | $350–650 | $300–800 | $300–500 |
| Median fixed broadband (Ookla 2026) | ~48 Mbps | ~243 Mbps | ~195 Mbps |
| Coworking, monthly | $60–120 | $70–190 | $40–150 |
| Long-stay visa | E-class + EB extension (~$285/yr), work permit now enforced | DTV: 5-yr, 180+180 days/entry, ~$285 | 90-day multi-entry e-visa ($50), no in-country extension |
| Healthcare | Weak; serious cases fly to Bangkok | Best in the region (medical-tourism grade) | Solid in HCMC/Hanoi; good in Da Nang |
| Nomad community | Thin, more expat/NGO/business | Chiang Mai is arguably the world's densest | Da Nang large and growing fast |
| Main seasonal pain | Hot season Mar–May, wet-season flooding | Chiang Mai burning season Feb–Apr | Da Nang typhoons/rain Oct–Dec |
The real dividing line in 2026: the visa
Cost and weather get all the attention, but the thing that actually decides where you can build a life is the visa — and this is where the three fully diverge.
Thailand pulled ahead here. The Destination Thailand Visa (DTV), launched in 2024, is a five-year multiple-entry visa aimed squarely at remote workers. Each entry lets you stay 180 days, extendable once inside Thailand for another 180 (about a year per entry) for roughly 1,900 THB. The visa itself is about 10,000 THB (~$285). The catch: you must apply from outside Thailand and prove 500,000 THB (~$14,000) in savings held for the prior three months. If you have the cushion, nothing else in the region matches it for a low-drama multi-year base.
Vietnam is the opposite trade. Its 90-day multiple-entry e-visa costs $50 and arrives by email in a few days — cheap and easy to get. But Vietnam does not allow you to extend or renew an e-visa from inside the country. When your 90 days end, you leave and apply again from abroad. In practice that means a quarterly "visa run" — a cheap hop to Bangkok, Phnom Penh, or Singapore — costing $150–400 a trip in flights and a night or two. Annoying, budgetable, but a real recurring tax on your time.
Cambodia used to be the easy answer and is quietly getting harder. You land, buy an E-class ordinary visa for $35, and extend it as an EB (business) extension — a 12-month extension runs around $285. For years this was the most frictionless indefinite stay in Southeast Asia. The change worth knowing: since 2024, Cambodia enforces work permits through its FWCMS system, and EB renewals are increasingly refused without one. Freelancers and remote workers are explicitly covered. It still works, but it now involves a work permit and a bit more paperwork than the "just extend forever" reputation suggests.
So the visa reality flips the intuition. Cambodia feels easiest for a first 90 days; Thailand is easiest for a stable multi-year base; Vietnam is easiest to enter but the least convenient to stay in continuously.
Cambodia: cheap, frictionless entry, thin backup
Cambodia's appeal is real and specific. Phnom Penh runs on US dollars, so you skip the mental currency conversion and much of the exchange friction — a genuine daily convenience. Rent is low ($350–650 for a comfortable one-bed with a pool and gym in a mid-range building), Khmer and international food is cheap, and the setup speed is fast: SIM, apartment, and a coworking desk can all happen in a day or two.
Its weaknesses are equally concrete. Internet is the headline problem — Cambodia's median fixed broadband sits near 48 Mbps versus roughly 195 in Vietnam and 243 in Thailand. For most work that's fine, but it means less headroom, and apartment Wi-Fi in Phnom Penh is more likely to wobble in storms, making a coworking backup less optional than elsewhere. Healthcare is the bigger risk: routine care is available, but for anything serious, expats budget for a flight to Bangkok. If you have health concerns, factor evacuation insurance in from day one. The nomad community is also thinner and skews toward NGO staff, teachers, and small-business expats rather than a dense remote-worker scene, so it can feel quiet if you want built-in professional networking.
Thailand: costs more, breaks least
Thailand is where the workweek simply works. Fixed broadband is the fastest of the three, private hospitals in Bangkok (Bumrungrad, Bangkok Hospital) are world-class and used to foreign patients, flight connections are the best in mainland Southeast Asia, and Chiang Mai has arguably the deepest, longest-running digital-nomad community anywhere. If your first apartment, SIM, or coworking space disappoints, replacing it is a same-day problem, not a crisis.
You pay for that depth. Chiang Mai is the value entry at roughly $1,200–1,800 all-in — rent from $300, coworking $70–100, cheap street food — while Bangkok runs $1,400–2,500 once you're in a good Sukhumvit-area building. The DTV's savings requirement is a real gate for younger or leaner nomads. And the honest seasonal weakness is Chiang Mai's burning season (roughly February to April), when agricultural smoke pushes air quality to some of the worst readings on earth — many regulars simply leave for those months. Choose Thailand if reliability, healthcare, and a long legal runway matter more than squeezing rent to the floor.
Vietnam: the value and speed play, taxed by admin
Vietnam is where the numbers get hard to argue with. Da Nang is the standout for 2026: a real beach, fast fibre, coworking from $40–150, and modern one-beds near My Khe for $300–500, with a genuine critical mass of remote workers — all-in budgets land around $700–1,100. Ho Chi Minh City trades the beach for big-city energy and better healthcare (FV Hospital and international clinics), while Hanoi is cheaper and more atmospheric but colder and grayer in winter. Internet is excellent nationwide, second only to Thailand here.
Vietnam's weaknesses are the visa treadmill described above and, in Da Nang specifically, a rainy/typhoon stretch from October into December that can flood streets and kill beach days for weeks. Apartment noise (construction, karaoke) is a common complaint across Vietnamese cities. But if you want the best cost-to-infrastructure ratio in the region and you don't mind planning a border hop every three months, Vietnam is the sharpest value in this trio.
The verdict
- Pick Thailand if you can park ~$14,000 in savings for the DTV, you want a multi-year base you barely have to think about, and healthcare or reliability is non-negotiable. Start in Chiang Mai for value (outside burning season) or Bangkok for city depth.
- Pick Vietnam if budget and internet speed lead your list, you want a beach-plus-community base, and quarterly visa runs are an acceptable price. Da Nang first; HCMC if you want a bigger city with better hospitals.
- Pick Cambodia if you want the lowest-friction entry, a dollar economy, and a genuinely cheap month or two — and you're healthy, insured for evacuation, and okay working around slower internet and a smaller scene.
A practical closing note: whichever you choose, you'll be paying visa fees, rent deposits, and the occasional cross-border run in a currency that isn't your home one. A multi-currency account like Wise keeps those transfers cheap and the exchange rate honest, which quietly matters more than any single line on the budget. The bigger decision, though, is the one above — match the base to your real constraint, not to whichever highlight reel looked best.
