Getting to Vietnam: Airports & Entry Points
Noi Bai International
Gateway to northern Vietnam — Hanoi's Old Quarter, Ha Long Bay, Ninh Binh and Sapa.

Gateway to southern Vietnam — the city itself, the Cu Chi Tunnels and the Mekong Delta.
Da Nang International
The convenient entry point for central Vietnam — Hoi An, Hue and My Khe Beach.

Getting Around Vietnam: Trains, Flights & Local Transport
Domestic flights
The fastest way to cover long distances, with budget carriers including VietJet Air, Bamboo Airways and Vietnam Airlines. Ho Chi Minh City -> Da Nang takes about 1.5 hours.
Reunification Express
One of the world's most scenic rail journeys: Hanoi -> Hue 12–14 h overnight · Hue -> Da Nang 3 h on the coastal stretch · Hanoi -> Sapa via overnight train to Lao Cai, then bus. Book sleeper berths.
Buses & city transport
Modern buses and limousine vans cover popular routes (Ho Chi Minh City -> Mekong Delta 2–3 h). In cities useGrab, Be or Gojek, metered taxis from reputable firms, and the new metro lines in Hanoi and Ho Chi Minh City.
Pro tip:reliable mobile data makes Vietnam dramatically easier — you'll use apps for train and flight tickets, Grab rides, navigation in the Old Quarter and finding the best food stalls. That's why aVietnam eSIMbelongs on your packing list.
Top 5 Must-Visit Destinations in Vietnam
Hanoi — Old Quarter, Lakes & Street Food
Wander the Old Quarter's 36 ancient streets, sip egg coffee by Hoan Kiem Lake, visit the Temple of Literature (Vietnam's first university) and the Ho Chi Minh Mausoleum complex, catch a water puppet show, and eat pho, bun cha and banh mi from tiny stools on the pavement.
Ha Long Bay & Ninh Binh — Limestone Karsts
Cruise among Ha Long Bay's 1,600 limestone islands and emerald water (UNESCO World Heritage), kayak through caves and lagoons, and visit floating fishing villages. Nearby Ninh Binh — "Ha Long Bay on land" — swaps crowds for rice paddies, karst scenery and easy cycling.
Hoi An & Da Nang — Lanterns & Beaches
Stroll Hoi An Ancient Town's lantern-lit streets after dark (UNESCO World Heritage), order tailored clothes, taste cao lau and white rose dumplings, cycle to An Bang Beach, then relax on Da Nang's My Khe Beach and explore the Marble Mountains.
Ho Chi Minh City — Energy & History
Bustling District 1, French colonial landmarks such as Notre-Dame Cathedral and the Central Post Office, the War Remnants Museum and Cu Chi Tunnels, rooftop bars, Ben Thanh Market and superb street food and cafe culture — plus the gateway to the Mekong Delta.
Sapa — Mountain Treks & Rice Terraces
Trek terraced rice valleys, stay in homestays with Hmong, Dao and Tay families, browse colourful weekend markets and enjoy cooler mountain air. The terraces are green in May–June and golden in September–October.

What is the best eSIM for traveling to Vietnam?

Combining Vietnam with Thailand, Singapore, Malaysia or Indonesia? TheSoutheast Asia 5 Regions eSIMcovers all five. Longer trips suit the 365-day 17 or 70-region plans.
How do I activate my Vietnam eSIM?
Connect to Wi-Fi first, open the email from UncleSim and scan the QR code to install your eSIM profile, then enable data roaming in your phone settings. About two minutes — do it before you fly or as soon as you land, so Grab and Maps work immediately.
Does the eSIM work outside the big cities — Sapa, Ha Long Bay and the Mekong Delta?
Yes. The Vietnam plans run on Vinaphone's nationwide network, covering Hanoi, Ho Chi Minh City, Da Nang, Hoi An, Hue, Ha Long Bay, Ninh Binh, Sapa and the Mekong Delta. Coverage in remote mountain valleys can be slower, as with any carrier.
Can I keep my home phone number while using a Vietnam eSIM?
Yes. The eSIM works alongside your existing physical SIM (dual SIM), so your home number stays active for calls and texts — check your carrier's roaming rates for voice — while the UncleSim eSIM provides your Vietnam data.
Is my phone compatible with an eSIM?
If your phone was bought in the last few years it almost certainly supports eSIM: iPhone XS or newer, and most recent Android devices. Check in Settings (Cellular or Mobile Networks > Add eSIM). No physical SIM needed, and you keep your home number active alongside it.
