Vietnam eSIM FAQs
Traditional calls and SMS aren’t part of our Vietnam eSIM packages - they’re strictly data provision. To talk or text, use internet - based services (WhatsApp, Signal, etc.) with your eSIM data.
No - our Vietnam travel eSIMs are data - only, so they don’t come with a voice line or phone number. Any calls or texts must go through internet apps like WhatsApp, Telegram, or Viber.
Yep! 99% of our eSIMs can be topped up within the ZenSim app with just a couple of clicks. If you run out of data, need more days, or you even want to add a new destination to the same eSIM, you can do all of this in the top up section in the Zen Garden in the app.
Log into the app, navigate to the Zen Garden, and you will see a button to tp up your eSIM right there.
Extending a long trip: If you're travelling for more than 30 days, you can add as many top ups as you need to your first eSIM to extend the days and data you have. Each top up will only take effect when the previous eSIM is expired so you can purchase the top ups any time you want without worrying about overwriting your existing plan.
Multi country top ups: You can now add multiple countries to most of our eSIMs via top up, so if you're in Europe for example and are stopping over in Dubai on the way home, you can add a Dubai top up to your Europe eSIM so you don't need to reinstall anything. Alternate country top ups will only activate when you arrive in the new country.
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 ☺️
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.
Yes! Your Vietnam eSIM can be installed as early as 30 days before you travel. It won’t start until you touch down in Vietnam.
Installing beforehand means no setup stress on arrival, and it won’t use any data or days until you land.
If you get an activation warning on iPhone when installing before arriving, that’s normal - check our eSIM Troubleshooting Guide for details.
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.
Connection Problems: If your Vietnam eSIM isn’t loading data, check our troubleshooting post. If that doesn’t do it, contact us and we’ll get you fixed up.
Installation Questions: Need help installing your eSIM? Visit our how-to guide, or shoot us a message at Contact Us and we’ll sort it out.
Anything Else: Got other queries? Visit our contact page and we’ll be right with you.
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.
Data and plan days only kick in when you arrive in Vietnam. Installing earlier just prepares it for activation which happens automatically when you arrive in Vietnam.
Install over WiFi before your trip to get connected from the minute you touch down.
If you have trouble connecting, see our eSIM Troubleshooting Guide or message us for assistance.
