Best travel eSIM Vietnam plans for Canadians
Updated October 9, 2026 · Cellulo Team
Land in Vietnam without a plan and your Canadian carrier starts billing $18/day. Stay a week and that's $126 for one phone, or $252 for two people, before you've even opened Google Maps in Ho Chi Minh City or booked a ride from the airport.
The best travel eSIM Vietnam option is usually whatever covers your trip length without pushing you into carrier roaming math that makes no sense. On Cellulo, Vietnam eSIM plans start at $6 CAD, activate automatically on arrival in Vietnam, and let you stay connected in Vietnam without hunting for airport Wi-Fi or a SIM kiosk after a long flight.
Why a Vietnam eSIM beats roaming
Vietnam is the kind of trip where mobile data matters right away. If you're landing in Hanoi, Da Nang, or Ho Chi Minh City, you need maps, hotel confirmations, and a working rideshare or messaging app the moment you step outside the airport. Arrive without data and you're stuck juggling screenshots, weak public Wi-Fi, or a roaming bill that keeps climbing by the day.
The math is blunt:
- 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
Compare that with a data plan for your Vietnam trip on Cellulo. A 7-day 1GB plan costs $6 CAD. Even the 10-day unlimited plan is $49 CAD, which is still far below the $180 you'd pay your Canadian carrier for the same trip length.
That matters if you're using Google Maps to navigate old quarters and side streets, calling home on WhatsApp or FaceTime, checking train or flight updates, translating menus, or uploading stories and reels while you travel. Business travellers get the same benefit: email, Slack, and video calls without coming home to a roaming charge that costs more than the hotel Wi-Fi was worth.

Which Vietnam eSIM plan makes the most sense
For most Canadians, the 7-day unlimited plan at $39 CAD is the sweet spot. It's long enough for a standard vacation and removes the need to ration data while navigating, messaging, translating, and posting on the go.
If you're taking a shorter trip, the 5-day unlimited plan at $27 CAD undercuts roaming fast. Your carrier would charge $90 over five days. If you're staying longer, the 30-day tiers are where the value gets obvious. The 10GB 30-day plan is $26 CAD, less than two days of carrier roaming. Even the 30-day unlimited plan at $98 CAD is still far below the $540 roaming bill from Rogers, Bell, or Telus.
The trade-off is simple: these are data-only plans. You won't get a local phone number, calls, or SMS. For most travellers, that isn't a dealbreaker because WhatsApp, FaceTime, Google Meet, iMessage, and other app-based services handle the communication side anyway.
How to use an eSIM in Vietnam without triggering roaming
Install your eSIM before you leave home. You'll need Wi-Fi for installation, and doing it in advance is easier than trying to sort it out after landing.
Once the eSIM is installed, keep your Canadian line turned off completely before you arrive in Vietnam. Not just data roaming off. Turn the line itself off in your phone's cellular settings. That's the step that helps avoid roaming charges.
Use the Vietnam eSIM for all data during the trip. If you need a one-time password or 2FA code sent to 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.
Plans activate automatically on arrival in Vietnam, so you can get online as soon as the phone connects to a local network.
Coverage and what to expect in Vietnam
A Vietnam eSIM connects to local networks in Vietnam. That's what makes it useful from the moment you land, whether you're booking a ride from the airport, pulling up a hotel address, or checking directions between neighbourhoods. In major cities and tourist corridors, staying connected in Vietnam is usually straightforward. In more remote or rural areas, coverage can be less consistent, so it's smart to download offline maps before day trips.
If your goal is to avoid roaming charges in Vietnam, the decision is mostly about trip length and how much data you'll actually use. Cellulo's Vietnam eSIM plans let you pick that balance directly at /travel/vietnam.
