Airport Taxi Scams That Charge Triple the Real Fare

At Tan Son Nhat (HCMC) and Noi Bai (Hanoi), unlicensed drivers aggressively solicit passengers inside and outside arrival halls, often posing as legitimate operators. According to Vespa A Go Go’s airport insider guide, these unsolicited drivers routinely charge triple the going rate, refuse to use a meter, or take deliberately long routes. The fix is simple: ignore all offers inside the terminal, walk to the official taxi queue or the designated Grab pickup zone, and book through the app before you leave the arrivals hall.

Telegram Is Blocked in Vietnam Since June 2025

As of June 2025, Vietnam’s government formally blocked Telegram nationwide, ordering all telecommunications carriers to enforce the ban. TechRadar confirmed the block took effect after the Ministry of Information issued the enforcement order in late May 2025. WhatsApp, Facebook Messenger, Instagram, and Zalo (Vietnam’s homegrown messaging app) all continue to work normally. If you use Telegram for group chats or travel coordination, switch to WhatsApp before you arrive.

MoMo Wallet No Longer Works for Most Foreigners

Vietnam’s most popular e-wallet, MoMo, tightened its identity verification rules from January 2025 onwards, requiring NFC chip-based ID scanning that most foreign passports cannot complete. A widely-cited Reddit thread on r/VietNam confirmed that foreigners are now largely locked out of MoMo registration. VNPAY is the better option for visitors: it accepts international Visa, Mastercard, and JCB cards and was specifically redesigned for international travelers, as noted by Da Nang’s official tourism portal.

Vapes Are Completely Banned. Don’t Bring Them

Vapes, e-cigarettes, and related products are prohibited from sale and import in Vietnam. The UK Government’s FCDO travel advice explicitly warns that you cannot buy vapes in Vietnam or bring them into the country.

Customs officials actively check for them, and penalties can be severe. If you vape at home, plan for the duration of your trip or consider nicotine patches as a substitute.

Bag-Snatching by Motorbike Is a Genuine and Common Threat

Motorcycle bag-snatching is one of the most frequently reported crimes affecting tourists in Vietnam’s cities, particularly Ho Chi Minh City. The FCDO safety advisory specifically warns to hold bags on the opposite side of the road from traffic and never to struggle with a thief, as injuries are common when people resist. Phone snatching from the hand while walking or sitting at a pavement cafe is also reported frequently in tourist districts.

The Viettel Network Matters More Than the Cheapest eSIM

All major networks perform well in Hanoi, HCMC, and Da Nang, but once you travel beyond the main cities. To Ha Giang, Sapa, Phong Nha, the Mekong Delta, or rural Phu Quoc.

The gap between Viettel and the other two operators (Mobifone, Vinaphone) becomes significant. Unusual Nomad’s independently verified 2026 coverage guide found that on the Ha Giang Loop, Viettel is the only network with meaningful coverage, while Mobifone and Vinaphone lose signal entirely between Dong Van, Meo Vac, and Lung Cu.

Saving a few dollars on a cheaper eSIM that uses a weaker network can mean no data for entire days on mountain roads.

Methanol Poisoning From Fake Spirits Is a Real Danger

There have been deaths and cases of serious illness in Vietnam caused by counterfeit alcoholic drinks containing methanol, including incidents in licensed bars and hotels in tourist areas. The UK’s FCDO travel advisory states that even small amounts of methanol can kill, and you cannot identify it by taste or smell. Buy drinks from well-known chains (like Highlands Coffee or major hotels), avoid mystery-priced spirits at small street stalls, and seek urgent medical attention if anyone shows signs of poisoning after drinking.

QR Code Payments Surged 51% in Vietnam in 2025. Use Them

Vietnam has rapidly become a QR-first payments country: black-and-white VietQR codes are now printed on windows, tables, and even around the necks of street performers. Phong Nha Explorer’s 2025 payments guide reported that QR code payment volume surged by nearly 51% in 2025. As a foreigner, you can use VNPAY (which supports international cards) to scan and pay VietQR codes without needing a Vietnamese bank account. Bypassing both ATM fees and the card terminal gaps at small vendors.

Fake Grab Drivers Are a Growing Scam at Airports

A widely-shared Reddit post on r/VietNam documents a specific scam where a driver quickly flashes a phone screen claiming to be your Grab match, then demands cash at the end and charges far more. Always verify the driver’s name, photo, car model, and license plate inside the app before getting in. If any detail doesn’t match, cancel and rebook.

Driving a Motorbike Without the Right Permit Is Illegal. And Costly

To legally drive a motorbike in Vietnam, you need both the 1968 version of the International Driving Permit (IDP) and your home country driving licence. The FCDO safety advisory is explicit that standard IDPs issued in most countries do not cover Vietnam’s requirements. If you’re involved in an accident without the correct documentation, you can face criminal charges, be required to pay compensation even if not at fault, and potentially face a travel ban while investigations are completed.

How To Travel Around Vietnam

Grab vs Be: Fixed Prices vs Local Discounts

Grab is the default transport option for most travellers in Vietnam’s cities. It replaced Uber in 2018 and now operates in 46 provinces and cities.

You get upfront fixed pricing, GPS tracking, driver details, and can pay by cash or linked card. For airport pickups in Ho Chi Minh City, the designated Grab zone at Tan Son Nhat is outside Domestic Exit D2; at Noi Bai in Hanoi, Grab zones are at both T1 and T2 arrivals.

Fares from Tan Son Nhat to District 1 run 150,000, 250,000 VND (~$6, 10 USD), compared to the 200,000, 300,000 VND that metered taxis charge. And scam taxis can charge far more.

The local alternative Be covers 28 cities and often undercuts Grab on price; it’s worth checking both apps for city rides in Hanoi and HCMC.

Electric Taxis and Domestic Flights for Longer Distances

Xanh SM is Vietnam’s first all-electric ride-hailing service, launched by VinGroup in 2023 and now operating in nearly 60 provinces. Reviews on the Apple App Store rate it highly for driver professionalism and vehicle quality, though its app is less polished than Grab and.

Critically. Does not yet accept international credit cards (Grab does).

For longer distances between cities, Vietnam’s domestic budget airlines (Vietjet, Bamboo Airways, Vietnam Airlines) offer frequent Hanoi-HCMC flights starting around $30, 50 USD booked in advance. The Reunification Express train is a scenic alternative taking 30, 40 hours with overnight sleeper options.

Less practical for time-pressed travellers but a genuine experience for those with flexibility.

HCMC vs Hanoi: Two Cities, Two Completely Different Transport Habits

Hanoi and Ho Chi Minh City have meaningfully different transport personalities. HCMC is chaotic and motorbike-heavy.

GrabBike (motorbike taxi) is often faster than a car in peak-hour gridlock, and Bus 109 (15,000 VND to Ben Thanh) is a cheap way to get from the airport. In Hanoi, the Old Quarter’s narrow streets make GrabBike or walking the smarter choice for short hops; the city also has a metro line (Metro Line 2A, Cat Linh, Ha Dong) that locals use but rarely features in tourist planning.

For day trips from Hanoi to Ninh Binh or Ha Long Bay, reputable private transfers booked via Grab or tour operators are far more reliable than flagging down random minibuses, which have poor safety records on rural highways.

Money: How Payments Actually Work

Cash Is Still King: What to Pack in Your Wallet

Cash remains king for daily life in Vietnam. Street food stalls, local pho shops, wet markets, motorbike taxis, small guesthouses, and most independent shops are cash-only or strongly prefer it.

Tonkin Travel’s 2025, 2026 currency guide confirms that while major hotels, shopping malls, and larger restaurants accept Visa and Mastercard, the vast majority of transactions a budget or mid-range traveller makes will require Vietnamese dong. Carry small denominations (10,000, 50,000 VND notes) for street food and tuk-tuks, as vendors often don’t have change for 500,000 VND bills.

Never attempt to use USD except at top-end tourist hotels. The informal USD economy that existed in tourist areas has largely faded and you’ll receive poor exchange value.

Which ATMs Don’t Charge Airport-Level Fees

ATMs are widely available in cities, airports, and convenience stores (Circle K, VinMart), but fees vary significantly. Phong Nha Explorer’s payment guide recommends seeking out VPBank or TPBank ATMs, which have historically offered lower or zero fees for international cards.

The airport currency exchange counters at Tan Son Nhat and Noi Bai offer worse rates than downtown gold shops or city bank branches. Only exchange enough at the airport to cover transport, then find a better rate in the city.

Changing money on the street is illegal and exposes you to scams involving counterfeit notes or short-changing. The FCDO explicitly warns to only use official exchange counters displaying the legal status sign.

VietQR and VNPAY: The Contactless Shortcut for Foreigners

Vietnam’s digital payment landscape moved fast in 2025. VietQR codes are now ubiquitous. Cafes, convenience stores, and even street stalls display them.

Foreigners can access QR payments without a Vietnamese bank account using VNPAY, which accepts international Visa, Mastercard, and JCB cards and was redesigned specifically for international visitors. Fizen’s 2025 payments guide notes that card acceptance roulette (some merchants say yes, some say no) is a real frustration for travellers relying solely on cards.

A QR-capable setup eliminates the constant ‘do you take cards?’ negotiation. MoMo, Vietnam’s largest e-wallet with 23 million active users, is largely inaccessible to foreigners as of 2025 due to new NFC ID verification requirements.

ZaloPay (linked to the popular Zalo chat app) is worth exploring for longer stays but similarly requires local registration steps.

Apps to Install Before You Leave

How Much Data You Actually Need in Vietnam

The biggest mistake travellers make is buying a small plan when larger data packs deliver far better value. Many underestimate the amount of data they need, then burning through a 1GB plan before lunch on day one. Here is what real activities consume per hour:

Phone Numbers and SMS

Most eSIMs sold to travellers are data-only plans with no Vietnamese phone number, which means you won’t receive SMS-based two-factor authentication (2FA) codes on your home number while in Vietnam. The practical workaround is a dual-SIM setup: keep your home SIM active on your device’s physical SIM slot (in low-data roaming mode to avoid charges) solely for receiving 2FA SMS, and use your travel eSIM for all data.

If your phone is single-SIM only, consider using an authenticator app (Google Authenticator or Authy) for your most important accounts before you leave, removing the SMS dependency entirely. Providers offering eSIMs with a local Vietnamese number are available if you need to register for local apps like ride-sharing or receive local calls from hotels and tour guides.

WhatsApp works normally and reliably in Vietnam.

It’s unaffected by internet restrictions and is the standard communication method for guesthouses, tour operators, and local contacts. Telegram was blocked in June 2025 and requires a VPN to access; VPNs themselves are not banned for tourists as of mid-2025.

Local emergency numbers are: 113 (police), 114 (fire), 115 (ambulance). The Vietnamese emergency services generally have limited English capability. If you need emergency help as a foreigner, contact your hotel front desk first who can assist with translation, or contact your country’s embassy in Hanoi or consulate in Ho Chi Minh City.

Where You Will Actually Use Your eSIM

Whether you spend your time in Vietnam in HCMC’s cafe culture or travels through Vietnam’s north to Ha Giang, coverage holds up across the main routes.

• Ho Chi Minh City (Saigon)Strong 4G and growing 5G coverage across Districts 1, 3, 7 and Thu Duc. You’ll use your eSIM constantly here. For Grab bookings, Google Maps navigation through the city’s chaotic one-way streets, GrabFood delivery, real-time translation of menus in the Ben Thanh Market area, and checking reviews before eating. Viettel has the most stable 5G rollout across central districts. Signal is consistent in all major tourist areas including Bui Vien backpacker street, the War Remnants Museum, and Cu Chi Tunnels.
• HanoiExcellent 4G coverage throughout the Old Quarter, Hoan Kiem Lake area, and beyond. You’ll rely on your eSIM for navigating the Old Quarter’s maze of narrow streets (many are one-way or motorbike-only), booking Grab from Noi Bai airport, researching temples and galleries, and booking overnight trains or buses forward to Ha Long Bay. The Grab pickup zone at Noi Bai requires you to walk some distance from the terminal. Have Google Maps open to find the correct exit.
• Ha Long BayMobile signal is intermittent on cruise boats and improves noticeably on the upper sun deck versus below deck. Ha Long Bay Cruises’ connectivity guide confirms 3G/4G is reachable from the sundeck on most vessels, while the restaurant area has the strongest onboard Wi-Fi. Download offline Google Maps of the bay and any walking areas (Cat Ba Island) before boarding. Most premium cruise operators offer onboard Wi-Fi but speeds are slow. Rely on your eSIM for anything important.
• Da Nang / Hoi AnAll three major networks perform well in Da Nang city and along My Khe Beach. In Hoi An’s Ancient Town (a vehicle-restricted UNESCO zone), you’ll use your eSIM for navigating lantern-lit alleyways, booking bicycle hire, and translating tailor shop sizing charts. Viettel maintains the most stable signal around the Marble Mountains and on the road between Da Nang and Hoi An. Coverage is consistent at all major beaches (Non Nuoc, An Bang).
• Sapa / Northern HighlandsCoverage is patchy outside town centres due to altitude and mountainous terrain. Unusual Nomad’s 2026 coverage guide found Viettel usable in most Sapa villages and along major roads, while Mobifone and Vinaphone drop out frequently on mountain passes. Download offline maps of the Muong Hoa Valley trekking routes before leaving Sapa town. For the Ha Giang Loop, Viettel is the only network with meaningful coverage between Dong Van and Meo Vac. Non-Viettel eSIMs will lose signal for extended stretches.
• Phu QuocStrong coverage in Duong Dong town and the main resort strip (Long Beach, Ong Lang). Viettel performs best on the island’s northern roads and the quieter eastern coast. Resort areas have strong Wi-Fi as a backup, but you’ll need mobile data for Grab bike rentals, booking boat trips to the Phu Quoc archipelago’s outer islands, and navigating to hidden beaches. Coverage thins out on dirt tracks to secluded northern beaches.
• HueGood 4G coverage in central Hue city and around the Imperial Citadel. Viettel performs best in rural districts and along the Perfume River. You’ll use your eSIM for navigating between the Imperial Citadel, royal tombs spread across a wide area, and Dong Ba Market. The road between Hue and Da Nang through the Hai Van Pass has variable signal. Download that section offline before the drive.
