Apps to Download Before Visiting Vietnam

The apps to download before visiting Vietnam are not the ones a generic packing list will hand you. What you actually need here is narrow: a way to get a ride at a fair price, maps that work with no signal, a translator with a camera, the messaging app Vietnamese businesses genuinely reply on, and a clear-eyed understanding that most of the country still runs on cash. Set all of it up on your home wifi before you fly, because an arrivals hall at midnight is a poor place to be creating accounts and waiting for verification codes.

Grab, and why it is the first install

Grab is the ride-hailing app of Southeast Asia and in Vietnam it is close to essential. It books cars and motorbike taxis, shows the fare before you accept it, records the driver and the plate, and removes the entire negotiation that causes most taxi trouble here. It also delivers food, which is useful on a jet-lagged first night. Create the account and add a card at home, because verification by text is easier on your own number. One or two local competitors, including an all-electric taxi fleet, are widely used in the big cities and worth carrying as a backup. Coverage thins out fast once you leave cities and tourist towns, where you go back to agreeing a price with a driver.

• Type the destination rather than dropping a pin. Vietnamese addresses with alley numbers confuse pin drops badly.
• At airports, walk to the marked app pickup zone instead of meeting a driver at the terminal door.
• Motorbike bookings are the cheapest and quickest way across a congested city, and the driver brings a spare helmet.
• Cash payment is usually offered, which matters on the day a foreign card gets declined.

Maps that work when the signal does not

Download the offline map for every region on your route while you are still on wifi. Coverage genuinely disappears on the mountain passes of the far north, among the karst around Ninh Binh and Ha Long, and inside the national parks. Two things to know about mapping here: walking directions will sometimes route you along a road with no sidewalk at all, and mountain driving times are optimistic because they take no account of switchbacks, trucks or fog, so add half again. A second offline mapping app built on open community data is worth carrying if you plan to trek, because it shows trails the mainstream one does not.

Translation, with the camera being the point

Install a translation app and download the Vietnamese language pack for offline use, meaning the actual download and not just the app. The camera mode is the feature that earns its place: point it at a menu, a bus timetable, a pharmacy box or a road sign and you get a live overlay in English. Vietnamese is tonal, so spoken translation is unreliable in both directions, while typed and photographed text works well. Type your sentence, turn the screen around, and let the other person type back. It feels slower and it works far better than trying to pronounce anything.

The messaging apps businesses actually answer on

This is the one nobody tells visitors. The dominant messaging app in Vietnam is Zalo, and it is where homestays, drivers, small hotels and tour operators reply, often within minutes, while an email sits unread for two days. It runs on a phone number, which is one more argument for a local SIM. Facebook Messenger is the second channel, because an enormous number of Vietnamese businesses run their whole customer service through a Facebook page. The app that is standard across much of the world is little used here. And send photos: a picture of the thing you want beats a paragraph in either language.

Money: what works and what does not

Here is the reality that surprises people. Vietnam looks like a cashless country, with a payment QR code taped to every counter, but those codes are bank transfers between Vietnamese accounts and the local wallet apps generally require a Vietnamese bank account and national ID. As a visitor you will not be using them. Cards work in hotels, malls, chain cafes and mid-range restaurants upward. Everything else, meaning street food, markets, most guesthouses, local buses, entry tickets and the parking attendant, is cash.

• Bring a debit card with low foreign-transaction fees and use ATMs attached to a bank branch in daylight.
• Per-transaction withdrawal limits are commonly in the two to five million dong range (roughly US$80-200), and machines usually charge somewhere around 20,000-60,000d (about US$1-2.50) per withdrawal, so take the maximum each time.
• Carry a currency converter that works offline and get used to counting zeros. Roughly, 100,000d is about US$4.
• Tell your bank you are traveling and keep a second card somewhere other than your wallet.

Do the downloads at home. Offline maps, the Vietnamese language pack, your ride-hailing account and your accommodation addresses saved in Vietnamese all take about fifteen minutes on a decent connection, and every one of them is painful to attempt for the first time in a taxi queue.

The rest of the apps to download before visiting Vietnam

• Your airline's app for domestic flights, which are the sensible way to cover the long north-to-south distances, plus whatever wallet holds your boarding passes.
• A weather app that shows tropical storm tracks. Typhoons between roughly August and November cancel Ha Long Bay cruises and disrupt flights along the central coast at short notice.
• The national railway operator's own booking site, saved as a bookmark, for the coastal train between Hue and Da Nang and the long runs out of Hanoi.
• Your eSIM provider's app, installed and the profile loaded, before you board rather than after you land.
• A notes file holding your accommodation names and addresses written in Vietnamese, scans of your passport and visa, your insurance policy number and the insurer's 24-hour emergency line.

A short pre-flight checklist

• Offline maps downloaded for every region, not just the first city.
• Accommodation addresses saved in Vietnamese, plus a screenshot of each booking confirmation.
• eSIM installed but not yet activated, and a power bank in your carry-on, because a dead phone in Vietnam means no map, no ride and no translator at once.
