Best travel eSIM Vietnam plans for Canadians
Updated May 27, 2026 · Cellulo Team
Land in Vietnam without a plan and your Canadian carrier starts billing $18/day. Stay a week and that turns into $126 for one person, or $252 for two, before you've even left the airport.
The best travel eSIM Vietnam option is usually cheaper than one or two days of roaming. Cellulo's Vietnam eSIM plans start at $6 CAD, activate automatically on arrival in Vietnam, and let you get online for maps, rides, hotel check-in emails, and messaging as soon as you land.
Vietnam is the kind of trip where mobile data matters right away. If you're landing in Ho Chi Minh City or Hanoi, you may need Google Maps before you even reach your hotel. Rideshare and local transport apps need a live connection. So do translation tools, booking confirmations, and the messages you forgot to screenshot before takeoff. Relying on airport Wi-Fi or hotel Wi-Fi is a gamble you don't need to take.
Best travel eSIM Vietnam plans compared
All of these are data-only eSIMs, so they do not include calls or SMS. For most travellers, that is fine: WhatsApp, FaceTime, Google Meet, Slack, Gmail, Maps, Grab, and banking apps all work over data.

How much you save versus roaming in Vietnam
The math is not close.
A 7-day trip on Rogers, Bell, or Telus roaming costs $126 at $18/day. Cellulo's 7-day unlimited Vietnam eSIM costs $38 CAD. That is an $88 difference for one traveller.
A 10-day trip costs $180 in roaming. The 10-day unlimited plan is $49 CAD. Savings: $131.
Even a longer 15-day trip works out better on eSIM. Carrier roaming hits $270. Cellulo's 15-day unlimited plan is $68 CAD, or $202 less.
If you barely use data, the gap gets even wider. A 7-day trip with the 1 GB plan costs $6 CAD instead of $126 in roaming. That is the kind of price difference that makes roaming feel outdated.
Which Vietnam eSIM plan makes the most sense
For most people, the 7-day unlimited plan at $38 is the safest pick. It covers a typical Vietnam trip without forcing you to watch your usage every time you open Maps, upload photos, or call home on FaceTime.
The cheaper fixed-data plans make sense if you know you'll mostly use hotel or cafe Wi-Fi and just need backup data for navigation, messaging, and ride bookings. The 1 GB 7-day plan at $6 and the 2 GB 15-day plan at $9 are hard to beat on price.
The unlimited options are better for travellers moving between cities, using translation apps throughout the day, or posting stories and reels in real time. If you're working remotely from Da Nang or Ho Chi Minh City, the 30-day 20 GB and 30-day unlimited plans are the practical choices.
How to use an eSIM in Vietnam without triggering roaming charges
Install the eSIM before you leave Canada because Wi-Fi is required for setup. Once installed, the plan activates automatically on arrival in Vietnam.
The important part is what you do with your Canadian line. Turn it off completely in your phone's cellular settings before landing. Do not just disable data roaming. If your Canadian line stays active, your carrier can still trigger roaming charges.
Use the Vietnam eSIM for all mobile data. If you need a one-time password or 2FA text from your Canadian number, turn your Canadian line on briefly, receive the code, then turn it off again.
Do not use Airplane Mode as a workaround. Airplane Mode disables the eSIM too, which defeats the point.
Will a Vietnam eSIM work well for travel?
A Vietnam eSIM is the easiest way to stay connected in Vietnam if you want data the moment you land. It connects to local networks in Vietnam, which is what you want for everyday travel use: maps, messaging, rideshare, email, and travel apps. Coverage can be less consistent in remote areas and smaller islands than in major cities, so travellers heading far outside Hanoi, Ho Chi Minh City, Da Nang, Hoi An, or Nha Trang should plan for some variation.
That trade-off still beats paying $18/day for roaming just to avoid swapping settings on your phone.
