Money, Safety & eSIM in Vietnam
Vietnam's currency is the Vietnamese dong (VND, often written with a comma for thousands) — carry cash for street food, markets, and small vendors; cards work at hotels, malls, and larger restaurants. Vietnam is very safe overall for tourists; the real everyday risk is road traffic, not crime — crossing the street and riding motorbikes both deserve real caution, even though locals make it look effortless.
The practical questions that actually matter once you land: how to handle a currency with a lot of zeros, what the real safety risks are (spoiler: it's the traffic, not the crime rate), and how to get online the moment you clear immigration.
Money and ATMs
The Vietnamese dong (VND) is the currency everywhere, and the number of zeros takes a day or two to get used to — a $5 coffee might show up as 125,000 VND on a menu. Check a current exchange rate before you go rather than relying on an old figure; as a rough planning anchor, $1 has recently traded in the mid-20-thousands of dong. Most ATMs charge a foreign-transaction fee (often a flat amount per withdrawal, sometimes with a lower daily limit than you're used to at home), so withdraw a reasonable amount at once rather than making frequent small withdrawals.
| Payment method | Where it works best |
|---|---|
| Cash (VND) | Street food, local markets, small shops, most taxis and motorbike rides |
| Credit/debit card | Hotels, malls, larger restaurants, chain convenience stores |
| Mobile wallets (Momo, ZaloPay) | Increasingly common, but generally require a Vietnamese phone number and bank link |
Is Vietnam safe?
Very safe by regional standards — violent crime against tourists is rare. The real, statistically significant risk is road traffic: motorbikes vastly outnumber cars, intersections often have no clear right-of-way, and crossing the street or riding a motorbike yourself both require genuine care, not just confidence.
How to cross the street (seriously)
This deserves its own section because it genuinely intimidates first-time visitors. The method that works: step off the curb at a slow, steady, predictable pace, keep walking (don't stop, don't run, don't backtrack), and let the motorbikes flow around you — they're constantly recalculating your position, and sudden movement is what actually causes near-misses. Cross with a local the first time or two if it helps build confidence.
Getting around
For long distances (Hanoi to Da Nang, Da Nang to Ho Chi Minh City), domestic flights are cheap ($30–70) and save a full day compared to the bus or train. For shorter or more scenic legs, Vietnam's Reunification Express train line runs the full length of the country and is a genuinely enjoyable way to see the countryside, especially the Hanoi–Sapa/Lao Cai and coastal Hue–Da Nang stretches. Within cities, use Grab (ride-hailing, cars and motorbike taxis) rather than hailing an unmetered taxi off the street.
The lower-stakes stuff
- Bag-snatching from passing motorbikes in busy tourist areas — keep bags on your inside shoulder, away from the road, especially in Ho Chi Minh City.
- Overpriced 'gem' or 'silk' shop stops added to cheap group tours, working on driver commission — politely decline and ask to skip straight to the next stop.
- Unmetered taxis quoting an inflated fare — always ask for the meter or use Grab, which shows the price before you book.
eSIM and staying connected
eSIM works well and is the easiest option if your phone supports it — Airalo and Holafly sell data-only plans from around $5–15 for 7–15 days, active before you even land. A physical local SIM (Viettel, Mobifone, or Vinaphone, sold at the airport or any convenience store) costs roughly $5–12 for two to four weeks of largely unlimited data and is just as easy to set up on arrival.
Water and food safety basics
- Don't drink tap water directly — bottled or filtered water is cheap and sold everywhere.
- Ice at busy, established restaurants is normally factory-made and fine; be a touch more cautious at very informal roadside stalls if you're sensitive.
