Your eSIM will activate automatically when you arrive in Vietnam. Though we recommend installing your Vietnam Travel eSIM before you arrive (this is different to activating).
To do this, scan the QR code we provide or install the eSIM directly from the ZenSim app while connected to WiFi. Once you arrive in Vietnam, your eSIM will activate automatically.
If you encounter any issues check out our eSIM Troubleshooting Guide or contact us directly ☺️
Not until you land in Vietnam. Installing ahead won’t start your plan; it goes live automatically when you arrive.
Make sure to install before you travel, as WiFi is required for setup and this way your Vietnam eSIM will be ready to use when you land.
If you encounter connection issues, see our eSIM Troubleshooting Guide or contact support.
The eSIM activates when you touch down in Vietnam — if you’ve already installed it, it should connect automatically.
Installing while already in Vietnam works too; it will start as soon as you complete setup.
If you experience connection issues, check our eSIM Troubleshooting Guide or reach out to our support team.
Good question! Opting for a travel eSIM instead of roaming in Vietnam offers clear advantages:
Lower Costs: Say goodbye to outrageous roaming bills by switching to a local travel package designed for Vietnam.
Seamless Switching: Change between data plans without fumbling with physical SIM cards - perfect for spontaneous travellers.
Budget Control: Track data usage in real time and avoid surprise charges or overages.
Absolutely! ZenSim’s eSIMs work in over 200 countries, and Vietnam is one of them. We also have regional eSIMs that cover several nations on a single plan - check out our Travel eSIMs page for details.
Definitely. Install your Vietnam travel eSIM up to 30 days before departure, and it will activate automatically when you arrive.
Installing early won’t consume data or days from your plan until you land in Vietnam.
If an iPhone shows an activation error when installing abroad, you can safely ignore it — check our eSIM Troubleshooting Guide for guidance.
Not exactly. Once your Vietnam eSIM is active, it’s tied to that country.
If you're visiting more than one place, our regional Travel eSIMs offer broader coverage so you can roam freely across multiple destinations.
Yes! You can top up any time via the ZenSim app. Log in and hit the top-up button to add more days or data.
For example, if you initially bought a 30-day plan but need more, just select another 30-day top-up and you’ll stay connected.
