eSIM Vietnam for Canadians: Hanoi, Saigon, Ha Long Bay (2026)

The best eSIM for Vietnam for most Canadians is a prepaid, data-only plan that connects to Vietnam’s major networks, Viettel, MobiFone and Vinaphone, with 5G, and that you install at home before the long flight. It costs far less than the $16 to $18 a day Bell, Rogers and Telus charge for international roaming, and it works from Hanoi to Ho Chi Minh City.

Vietnam is a country you travel through rather than stay put in: a typical route runs from Hanoi and Ha Long Bay down through Hue and Hoi An to Ho Chi Minh City and the Mekong Delta. That means maps, ride-hailing, train and bus bookings and translation every day. This guide covers what roaming costs, which networks to look for, how to use Grab and maps safely, how much data you need and how to set up your Vietnam eSIM.

How much does roaming in Vietnam cost for Canadians?

Bell, Rogers and Telus bill Vietnam at their international rate. You pay for every day your Canadian line uses data, calls or texts abroad, and the Government of Canada’s guide to using mobile devices abroad warns that background app activity can trigger charges without you noticing.

Carrier and plan	Daily rate in Vietnam	7 days	14 days	21 days
Bell Roam Better	$16	$112	$224	$320 (20-day cap)
Rogers (daily roaming)	$18	$126	$252	$378
Telus Easy Roam	$18	$126	$252	$378

Canadian dollars before tax, October 2026 rates, per phone. Bell stops charging after 20 days per line in a billing period, according to its travel page. Rogers also sells International Travel Passes for 180+ destinations at $45 for 3 days, $75 for 7, $100 for 14 and $120 for 30, which cost less than its daily rate on a long trip; check that Vietnam is listed on Rogers’ roaming page before you rely on one.

Vietnam trips from Canada often last three weeks. At daily rates, a couple pays roughly $640 to $760 in roaming over that time, and a family of four double that. Our Bell, Rogers and Telus roaming vs eSIM guide explains how the carrier plans compare.

What is the best eSIM for Vietnam?

A good Vietnam eSIM runs on networks with wide coverage, gives you enough data for daily navigation and ride-hailing, and starts counting only when you land. When you compare plans, look at:

• Network access: a plan that can reach several Vietnamese networks gives your phone a fallback in the northern mountains, on the central coast and in the Mekong Delta.
• 5G in the cities: useful in Hanoi and Ho Chi Minh City, where you will book rides and check maps constantly.
• Validity that starts on arrival: install at home and land at Noi Bai or Tan Son Nhat airport with data already working.
• Hotspot: handy for a laptop or a travel partner whose phone does not support eSIM.
• Plan size: a long, multi-stop trip calls for more data than a short city break.

Our Vietnam plans connect to Viettel, MobiFone and Vinaphone, with 5G. Your phone joins whichever network has the strongest signal where you are. Plans are data-only, so your Canadian number stays on the phone for calls and texts, and the days start when the eSIM first connects in Vietnam.

The plan page lists every network and shows whether hotspot is included under “Coverage & networks”. You can see all the operators our plans use on our mobile networks page, and if you are curious whether 5G matters on holiday, read our guide to 5G vs 4G when travelling.

Travel eSIM or a local SIM card?

You can also buy a Vietnamese SIM card after you arrive, which gives you a local number. It usually means finding a shop or airport counter after a long flight and swapping out your Canadian SIM. A data-only eSIM is already working when you land and leaves your Canadian SIM in place for bank codes. If you need a Vietnamese number for a long stay or local business, a local SIM is the better fit.

Hanoi eSIM: maps, Grab and the Old Quarter

Hanoi’s Old Quarter is a tangle of narrow streets named after the trades once practised there, and traffic moves in every direction at once. A Hanoi eSIM lets you follow a walking route through it, find street food stalls, book a car to the train station and translate signs and menus.

Grab is the ride-hailing app most visitors use in Vietnam. Its Vietnam site lists rides, food and grocery delivery, parcel delivery and an in-app wallet. Because Grab only needs mobile data and location, it works on a data-only eSIM. Sign in before you leave Canada, while your account’s verification texts can reach your Canadian number without any fuss.

The Government of Canada’s travel advice for Vietnam has three points worth knowing in the cities:

• Use official taxis or a trusted ride-hailing app, confirm the fare in advance or insist on the meter, and never share a taxi with a stranger.
• Avoid motorcycle taxis. Canada considers xe om rides unsafe, so choose a car option in your ride app.
• Be careful on public Wi-Fi. The page lists cybercrime on public Wi-Fi among the risks, which is one more reason to use your own mobile data for banking and bookings.

Ha Long Bay: what to expect from signal on a cruise

Ha Long Bay, a few hours east of Hanoi, is famous for thousands of limestone islands rising from the water. Most visitors take a day cruise or an overnight boat. Your Vietnam eSIM works in the bay, but signal can weaken among the karsts and further out from shore, so screenshot your booking and pickup details before you leave Hanoi.

Choose your boat with care. The Government of Canada reports boat accidents caused by overloading and poor maintenance, including in Ha Long Bay, and advises using a reputable operator and not boarding vessels that look overloaded or in poor condition. Having data on board lets you check weather updates and stay in touch with family.

Weather matters here too. Canada’s advice says typhoons usually occur between June and December, so keep an eye on forecasts and any cruise cancellations if you travel in those months.

Tip: Save Hanoi, Ha Long, Hoi An and Ho Chi Minh City as offline areas in Google Maps and download Vietnamese in Google Translate while you are still on Wi-Fi at home. Both keep working when the signal drops on a boat or a mountain road.

Hoi An and the central coast

Hoi An’s old town, with its lantern-lit streets and riverside cafés, is a short ride from Da Nang airport. Your Vietnam eSIM is useful for booking a Grab from Da Nang, finding tailors and restaurants, and arranging day trips to My Son or the beaches.

Timing matters on the central coast. The Government of Canada says the rainy season in central Vietnam runs from October to December, and seasonal flooding occurs there in October and November. If you visit then, follow local weather news and road updates on your phone and allow flexibility in your plans.

Ho Chi Minh City and the Mekong Delta

Ho Chi Minh City, still widely called Saigon, is Vietnam’s biggest and busiest city. You will lean on data for rides between districts, restaurant searches, museum hours and day trips to the Cu Chi tunnels or the Mekong Delta. Seasonal flooding is also common in the Mekong Delta, according to the Government of Canada, and the rainy season in the south runs from June to September.

Canada’s advice also lists card and ATM fraud, overcharging at bars and nightclubs, drugged drinks and snacks, and methanol-contaminated alcohol among the risks. Stick to reputable brands of alcohol, keep an eye on your drink and use bank ATMs in public places.

Before you fly: visa, registration and emergency numbers

Unlike many Asian destinations, Vietnam requires Canadians to have a visa. At the time of writing, the Government of Canada says holders of a regular Canadian passport can apply online for a single- or multiple-entry tourist e-visa valid for up to 90 days, and must enter through the port of entry named on the approval. Apply only through Vietnam’s official national e-visa website, and make sure your passport is valid for at least six months beyond your planned departure date.

Vietnam also requires visitors to register their presence with local authorities on arrival. Hotels usually do this for you, and the Government of Canada advises asking for your passport back after check-in.

Service	Number
Police	113
Fire	114
Medical assistance	115

How much data do you need in Vietnam?

Vietnam trips involve a lot of moving around, and travellers use their phones for transport, translation and bookings every day. As a rough guide for one phone:

Type of trip	Typical use	Suggested data
One week, Hanoi and Ha Long Bay	Maps, Grab, messages, photos	5 GB
Two weeks, north to south	Daily navigation, translation, social media	8 to 15 GB
Three weeks or longer	Heavy maps use, video calls home, uploads	15 to 20 GB
Working remotely or sharing a hotspot	Video calls, cloud files, laptop use	20 GB or more

Video calls, streaming and camera translation use the most data. Set photo backup to Wi-Fi only and pause app updates on mobile data. Our guide to how much data you need when travelling breaks usage down by app, and our guide to sharing mobile data abroad explains how families can share one connection.

How to set up your Vietnam eSIM before you fly

Setup takes about five minutes on home Wi-Fi, and doing it before the flight means you land with data ready. The validity only starts when the eSIM first connects in Vietnam, so installing it early costs nothing.

1. Check your phone. It needs eSIM support and must be unlocked. Use our compatibility checker or our guide to checking if your phone is eSIM compatible.
2. Buy your Vietnam plan. The QR code arrives by email, usually within about a minute. Travelling as a group? You can buy up to 10 eSIMs in one order and send each QR code to its own email. Each eSIM installs on one phone only.
3. Install it on Wi-Fi. On iPhone, follow Apple’s eSIM setup guide. On Android, open Settings, find SIM manager or Network and internet, and add an eSIM by scanning the code.
4. Label your lines. Name the new one “Vietnam” and your usual one “Canada”.
5. When you land, turn on the Vietnam line, enable data roaming for it and set it as your mobile data line.
6. Turn data roaming off on your Canadian line, including during any stopover in Asia, so your carrier cannot start a daily charge.

Apple’s guide to using Dual SIM with an eSIM explains how your Canadian line can stay on for texts, such as bank codes, while the Vietnam eSIM carries your data. Our guide to keeping your Canadian number with a dual SIM covers the set-up in more detail.

For phone-by-phone steps, read our guide to installing an eSIM before you fly. If the eSIM does not connect on arrival, try our eSIM not working abroad fixes or visit the help centre.

Visiting Vietnam as part of a bigger Asia trip?

A Vietnam plan covers Vietnam only. Many Canadians combine it with Thailand, Cambodia or a stop in Japan or Korea. For a multi-country route, look at our global plans, which list every country covered, or pick a plan for each stop from our destinations list. Our Thailand eSIM guide and Japan eSIM guide cover two popular add-ons.

Your next step

Check your phone with our compatibility checker, then compare every Vietnam eSIM plan by data and validity. Install it at home on Wi-Fi, switch it on when you land in Hanoi or Ho Chi Minh City, and keep your Canadian line’s data roaming off for the whole trip.
