Question 1

Which Vietnam eSIM plan fits a short trip vs a heavy-data trip?

Accepted Answer

For a short city break or light browsing, a 1–5 GB fixed-data plan is usually enough and costs less. For longer trips, remote work, or heavy streaming, look at daily unlimited plans — they give you a set high-speed allowance each day (often 500 MB–2 GB/day) with reduced-speed fallback. The right choice depends on how many days you're traveling and how much you rely on data-heavy apps.

Question 2

Should I choose a daily unlimited or fixed-data Vietnam eSIM?

Accepted Answer

Daily unlimited plans give you a set high-speed data bucket each day (e.g., 500 MB or 1 GB/day). If you hit the limit, data continues at reduced speed. Fixed-data plans give you a total pool to use however you like over the plan duration — but data stops when you run out. Choose daily if you want predictable per-day costs; choose fixed if your usage varies day to day.

Question 3

When does my Vietnam eSIM validity start?

Accepted Answer

It depends on the plan you choose. First network connection (On Arrival): The validity starts only when you arrive in Vietnam and connect to the local network. Most plans use this policy. First installation (Immediate): The validity starts immediately after you install the eSIM. Some plans use this policy. Please check the "Activation Policy" listed in the plan details above to see which one applies.

Question 4

Can I use Personal Hotspot with Vietnam eSIM?

Accepted Answer

Yes, absolutely! Personal Hotspot is fully supported for Vietnam eSIM plans. You can share your connection with your laptop, iPad, or travel companions. Perfect for working remotely during your trip.

Question 5

Is my phone compatible with Vietnam eSIM?

Accepted Answer

Most modern phones are supported. The quickest way to check is to dial *#06# on your phone. If you see an EID number (32 digits) on the screen, your phone supports eSIM! Check our full list of compatible devices at /esim-compatible-devices. (Note: iPhones purchased in China Mainland usually do not support eSIM.)

Question 6

How do I install and activate Vietnam eSIM?

Accepted Answer

It's instant and paperless. After purchase, you will receive a QR Code via email. 1. Scan the code in your phone's Settings > Cellular > Add eSIM. 2. When you land in Vietnam, turn on Data Roaming for this eSIM line. 3. You will connect to the best local network automatically.

Question 7

What happens if I use up my high-speed data?

Accepted Answer

This varies by plan type: Daily Plans (e.g., 500MB/Day): You get Unlimited Data. If you hit the daily high-speed limit, you can continue using data at a reduced speed (usually not lower than 256kbps) under the Fair Usage Policy (FUP). Fixed Data Plans (e.g., 10GB Total): These plans do not have FUP. The data service will stop immediately once the total limit is reached. We recommend buying a larger plan if you are a heavy user.
