Can I use the same eSIM for a day trip to Ha Long Bay or Sapa?

Yes. This is a single national Vietnam plan, so the same eSIM keeps working when you head out to Ha Long Bay, Ninh Binh or Sapa. Signal can thin on remote mountain roads and out on the water between the karsts.

Is data fast enough in the Old Quarter?

Very. Central Hanoi has dense 4G and growing 5G, so maps, GrabBike bookings and video calls all run smoothly between the tall shophouses. The only real weak spots are deep inside older buildings and crowded market basements.

Navigate Hanoi's Old Quarter, Hoan Kiem Lake and lantern-lit Train Street without losing signal.

Good to know in Hanoi

Grab's motorbike option (GrabBike) is the fastest way through Hanoi's gridlocked Old Quarter, and far cheaper than a car; you will need live data to book one and share your exact pin down the narrow lanes.

Does an eSIM work in Hanoi?

Yes — the Vietnam eSIM works in Hanoi wherever its partner networks have signal. Viettel, VinaPhone and MobiFone give strong 4G and expanding 5G across central Hanoi, the West Lake area and out to Noi Bai; coverage only really dips inside old shophouse basements and crowded covered markets.

Your guide to Hanoi

Hanoi eSIM: your local data guide.

Hanoi rewards constant navigation, from weaving motorbikes in the Old Quarter's 36 guild streets to finding the right platform on Train Street and timing the weekend walking street around Hoan Kiem Lake. A Hanoi eSIM keeps Grab, Google Maps and Google Translate live the moment you land, so ordering bun cha and booking a Ha Long day trip never means hunting for cafe Wi-Fi.

One eSIM for Hanoi and all of Vietnam. It's the national Vietnam eSIM — from £1.53/day with unlimited data, working the same in Hanoi as it does the moment you leave it.

Landing at Noi Bai International Airport (HAN)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

Hoan Kiem Lake

Check weekend walking-street hours and Ngoc Son Temple times, then share sunset photos from the red Huc Bridge.

Train Street (Phung Hung)

Look up the day's train timetable so you know exactly when to step back for the carriages that thread past the cafes.

The short version.

A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in Hanoi, and it finds a partner network on its own.
