Best travel eSIM Vietnam plans for Canadians
Updated June 5, 2026 · Cellulo Team
Land in Vietnam without a plan and your Canadian carrier starts billing $18 per day. Stay a week and that is $126 for one person, or $252 for two, which is more than most travellers need to spend to stay connected for the whole trip.
The best travel eSIM Vietnam option depends on how long you are staying and how much data you will actually use, but the math is easy: Cellulo's Vietnam eSIM plans start at $6 CAD and top out at $101 CAD for 30 days of unlimited data. Even the 7-day unlimited option at $38 undercuts a week of carrier roaming by $88.
If you are landing in Ho Chi Minh City, Hanoi, or Da Nang and need Google Maps, Grab, hotel confirmations, translation apps, and WhatsApp working the moment the plane touches down, a Vietnam eSIM solves the biggest travel headache before the trip starts. You install it at home on Wi-Fi, it activates automatically on arrival in Vietnam, and you skip the airport SIM kiosk line entirely.

How much you save versus roaming in Vietnam
A Canadian carrier charges the same $18/day whether you use a little data or a lot. That flat daily fee adds up fast.
- 3 days in Vietnam: $54 in roaming vs $16 for unlimited data
- 7 days in Vietnam: $126 in roaming vs $38 for unlimited data
- 15 days in Vietnam: $270 in roaming vs $69 for unlimited data
- 30 days in Vietnam: $540 in roaming vs $101 for unlimited data
For a couple travelling together, a 10-day trip can mean $360 in roaming charges. Two 10-day unlimited Vietnam eSIMs cost $98 total. That is the kind of difference that pays for airport transfers, a hotel night, or a lot of banh mi.
The 7-day unlimited plan is the strongest middle ground for most travellers. It covers a typical Vietnam trip without forcing you to ration maps, rideshare bookings, restaurant searches, or video calls home. If you are posting stories, uploading reels, or working remotely between cities, the 15-day or 30-day larger plans make more sense.
Why a Vietnam eSIM matters on arrival
Vietnam is easy to navigate once you are connected. It is harder the moment you land without data.
Most travellers need a live connection right away for Grab, maps, booking emails, and messaging. If you are arriving late, switching hotels, or heading straight from the airport to another city, waiting to find public Wi-Fi is a bad plan. Hotel Wi-Fi is often fine for basic browsing later, but it is not something you want to rely on for airport pickup details, banking logins, or sensitive work messages.
A data plan for a Vietnam trip also matters outside the big tourist moments. Translation apps need data when menus are not in English. Google Maps matters when a driver drops you on the wrong street. Business travellers need email, Slack, and video calls without wondering what bill is waiting back home. If you are creating content as you go, you need consistent mobile data across the day, not just when you get back to the hotel.
These eSIMs connect to local networks in Vietnam. Coverage is generally strongest in cities and major tourist corridors. In rural or mountainous areas, expect coverage to be less consistent than in Hanoi or Ho Chi Minh City.
How to set up your Vietnam eSIM properly
Install the eSIM before you leave Canada. You need Wi-Fi for installation, so do not wait until you are in transit.
Once the eSIM is installed, keep it ready for the trip and turn your Canadian line off completely before landing in Vietnam. 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 passcode or 2FA text on your Canadian number, turn that line on briefly, receive the code, then turn it off again.
Do not use Airplane Mode as your workaround. Airplane Mode disables the eSIM too. Turn off the Canadian line specifically in your phone's cellular settings and leave the Vietnam eSIM active.
Which Vietnam eSIM plan should you buy?
If your trip is under a week and you use your phone normally, the 7-day unlimited plan at $38 is the safest pick. If you mostly need maps, messaging, and occasional browsing, the 1 GB or 2 GB options are cheap and practical. If you are staying a month, the 10 GB and 20 GB plans hit the best value for most people, while the 30-day unlimited plan is there for heavy users who do not want to think about data limits at all.
For Canadians trying to avoid roaming charges in Vietnam, the simplest move is to pick the plan that matches your trip length on Cellulo and have it ready before departure.
