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.

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.

Two simple ways to buy

Hanoi eSIM plans: unlimited, or by the GB.

Every Hanoi eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Hanoi — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Plan your data

How much data do you need in Hanoi?

A rough, honest guide to sizing your Hanoi eSIM so you're not guessing. Most travellers in Hanoi are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

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 $3.20/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.

On the ground

Where you'll lean on data in Hanoi.

Old Quarter

Follow Google Maps through the 36 narrow guild streets and pull up reviews before diving into a street-food stall.

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.

West Lake (Tay Ho)

Order a Grab out to the lakeside cafes and Tran Quoc Pagoda, then split the bill and translate the menu on the spot.

The practical bit

Getting around Hanoi on your eSIM.

Apps you'll want online in Hanoi

Grab— Vietnam's dominant super-app for car and motorbike rides, food and payments; needs data.
be— Popular Vietnamese ride-hailing app; a handy backup when Grab is surging in the Old Quarter.
Xanh SM— VinFast's green electric taxis and bikes, booked in-app and spreading fast across Hanoi.
Hanoi Metro— Buy tickets and check times for the Cat Linh-Ha Dong and Nhon elevated lines.

How long to stay in Hanoi

Most travellers spend two to three days in Hanoi, covering the Old Quarter, Hoan Kiem Lake, the Ho Chi Minh Mausoleum and a food tour before a Ha Long cruise.

How much data for Hanoi

For a two or three-day Hanoi stay, 3-5 GB comfortably covers Grab rides, live maps, translation and social posts; pick Unlimited if you plan to stream or hotspot a laptop from your hotel.

Coverage in Hanoi

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.

Peace of mind

Your Hanoi eSIM: data-only, zero bill shock.

Your Hanoi eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Hanoi, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
