Best travel eSIM Vietnam plans for Canadians
Updated July 12, 2026 · Cellulo Team
Land in Vietnam without a plan and your Canadian carrier starts billing at $18/day. Stay a week and that becomes $126 for one person, or $252 for two, before you've even opened Google Maps outside the airport.
The best travel eSIM Vietnam option is usually cheaper than one or two days of roaming. If you just need light data, Cellulo's 1 GB for 7 days costs $6. If you want to use maps, rideshare, messaging, and uploads all week without watching your usage, the 7-day unlimited plan is $39.
Why a Vietnam eSIM beats roaming
Vietnam is the kind of trip where data matters right away. Land in Ho Chi Minh City or Hanoi without connectivity and you're stuck hunting for airport Wi-Fi, trying to load hotel details, or guessing whether your rideshare app will work when you step outside. If you're heading straight into traffic with a driver, meeting a tour, or navigating to a train, that delay gets old fast.
A data-only eSIM fixes that before you leave Canada. You install it at home over Wi-Fi, it activates automatically on arrival in Vietnam, and your phone connects to a local network once you land. That means Google Maps works from the airport, Grab or other ride apps can load properly, and your booking emails, QR codes, and travel documents are available when you need them.
It also cuts out the usual hotel Wi-Fi gamble. Some hotels are fine. Some are overloaded, slow, or not a network you want to trust for banking, work logins, or video calls home. If you're travelling for work, reliable mobile data matters even more for email, Slack, and meetings. If you're posting stories and reels as you move between cities, small data caps disappear quickly.

What plan makes sense for your Vietnam trip
For most travellers, the 7-day unlimited plan at $39 is the sweet spot. It covers a standard one-week trip without forcing you to ration maps, translation apps, social media, or video calls. Compared with carrier roaming, the math is blunt: $18/day x 7 days = $126. The eSIM saves $87 on a solo trip.
If you're going for a quick long weekend, the 3-day unlimited plan at $17 is almost the same price as one day of roaming. For five days, $27 still undercuts roaming by a wide margin since carrier roaming would hit $90.
The smaller 1 GB, 2 GB, 3 GB, and 5 GB plans make sense if you mostly use hotel Wi-Fi and just want data for navigation, messaging, and the occasional lookup while you're out. They are cheap, but the trade-off is obvious: once you start using maps all day, uploading photos, or taking video calls, those caps can disappear fast.
For longer trips, the 10 GB for 30 days at $26 and 20 GB for 30 days at $42 stand out. A month of carrier roaming would cost $540. Even the 30-day unlimited plan at $103 is still far below that.
How to set up your Vietnam eSIM properly
Install your eSIM before you leave home because setup requires Wi-Fi. Don't wait until you're in the airport trying to connect on public internet after a long flight.
Once the eSIM is installed, turn your Canadian line off completely before landing in Vietnam. Don't just disable data roaming. If your Canadian line stays active, your carrier can still trigger roaming charges. If you need a one-time passcode or 2FA text, turn the Canadian line on briefly, receive the code, 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 active and switch off the Canadian line specifically in cellular settings while using the Vietnam eSIM for data.
What to expect from a Vietnam eSIM
A Vietnam eSIM gives you mobile data on local networks, which is what most travellers actually need. It won't replace your Canadian number for calls or texts because these are data-only plans, but apps like WhatsApp, FaceTime, Messenger, and Google Meet still work over data.
That makes a difference the moment you arrive. You can message your hotel, call home through an app, pull up directions, translate signs and menus, and book transport without touching carrier roaming. For Canadians trying to avoid surprise charges, that's the whole point.
