Best travel eSIM Vietnam plans for Canadians
Updated August 21, 2026 · Cellulo Team
Land in Vietnam without a plan and your Canadian carrier starts billing at $18/day. Stay 10 days and that is $180 for one line, or $360 for two people, before tax.
That is why the best travel eSIM Vietnam option usually beats roaming on day one. A 10-day unlimited Cellulo Vietnam eSIM costs $48 CAD, activates automatically when you arrive in Vietnam, and keeps your phone usable for maps, rides, messages, and bookings without a surprise bill waiting at home.
Why a Vietnam eSIM beats roaming
Vietnam is the kind of trip where mobile data matters the moment you land. If you are arriving in Ho Chi Minh City, Hanoi, or Da Nang, you will likely need Google Maps to get out of the airport, a rideshare app to reach your hotel, and your booking emails or check-in details on hand. Arriving with no data means hunting for airport Wi-Fi, hoping it works, and wasting time when you are tired.
Carrier roaming makes that convenience expensive fast. A week in Vietnam costs $126 in roaming fees at $18/day. Two weeks costs $252. For a couple travelling together, that jumps to $504. By comparison, Cellulo's 15-day unlimited Vietnam eSIM is $67 CAD, while lighter travellers can get 15 days with 2GB for $9 CAD.
For many Canadian travellers, that is the real appeal of an eSIM Vietnam plan: your phone works when you land, your maps load on the street, translation apps stay live, and you can message home on WhatsApp or FaceTime using data instead of paying international roaming rates.
Best travel eSIM Vietnam plans on Cellulo
All Cellulo Vietnam plans are data-only eSIMs. They do not include local calls or SMS, so they are best for travellers who use apps for messaging and calling. If you need a one-time bank code or 2FA text, briefly turn your Canadian line back on, receive the code, then switch it off again.

The 7-day unlimited plan at $38 is the strongest middle ground for most travellers. It undercuts roaming hard, covers a typical one-week trip, and removes the need to ration data for maps, rides, uploads, or video calls.
Roaming math for a Vietnam trip
Here is how quickly the gap opens up:
- 3 days of carrier roaming: $54
- 7 days of carrier roaming: $126
- 10 days of carrier roaming: $180
- 15 days of carrier roaming: $270
- 30 days of carrier roaming: $540
Against that, Cellulo's Vietnam eSIM plans start at $6 CAD and top out at $96 CAD for 30 days of unlimited data. Even the 30-day unlimited plan costs less than six days of roaming.
If you are travelling as a couple for 7 days, roaming would cost $252 total. Two 7-day unlimited eSIMs cost $76 total. That is a $176 difference, and you still get data as soon as you arrive.
How to use an eSIM in Vietnam without triggering roaming
Install the eSIM before you leave Canada. You will need Wi-Fi for setup, and doing it at home is easier than trying to sort it out in an airport.
Once the eSIM is installed, keep your Canadian line turned off completely before landing in Vietnam. Do not just disable data roaming. If your Canadian line stays active, your carrier can still register you on a partner network and trigger the $18/day roaming charge.
Use the Vietnam eSIM for all mobile data during the trip. If you need an OTP or 2FA text sent to your Canadian number, turn that line on briefly, receive the message, then switch it off again.
Do not use Airplane Mode as a workaround. Airplane Mode disables the eSIM too. The safer move is to leave your phone's cellular service on and switch off the Canadian line specifically in your cellular settings.
Cellulo's Vietnam eSIM plans activate automatically on arrival in Vietnam, so you do not need to visit a kiosk or swap a physical SIM card.
What kind of traveller should pick which Vietnam eSIM
If your trip is built around cities, food tours, day trips, and constant navigation, unlimited data is usually worth it. Vietnam is easy to explore with a phone in hand, but only if your connection is live when you need directions, ride pickups, train details, or translation help.
If you are staying longer and mostly using hotel or cafe Wi-Fi, one of the 30-day capped plans can make more sense. The 10GB 30-day plan at $25 is a practical middle option for business travellers who need email, Slack, and occasional video calls on the go. The 20GB plan at $41 fits travellers posting stories, uploading reels, or working across multiple cities.
Coverage depends on the local networks the eSIM connects to in Vietnam. In major cities and tourist corridors, that is usually enough for most travellers. In remote or rural areas, expect coverage to be less predictable than in central urban areas.
If you want to stay connected in Vietnam without paying $18 a day to roam, start with Cellulo's Vietnam eSIM plans and pick the one that matches your trip length and data use.
