Reviews: Vietnam 5G eSIM | Day Pass/Total Data Package | 1–30 Days | 24-Hour Billing | QR Code

Guest User2025-12-25

Great value compared to other "branded" eSim providers, I had downloaded the eSim prior to arrival in Vietnam and it connected without issue once my flight had landed. Only possible downside is there doesn't appear to be an app to track usage so you are reliant on your phones view of data usage.

Guest User2025-11-24

That was really easy to install and use it. I was even able to use it on the island. Highly recommend 🔥

★

Guest User2025-12-25

Good internet. Suitable for work. The only downside is that they don't explain how to check the remaining data on your package. The commands don't work because the plan is internet-only.

Guest User2025-12-24

It's very convenient. You're already connected as soon as you arrive in the country. It works reliably and is very affordable.

★

Guest User2025-12-10

It works! I pre-installed SMS to Kuala Lumpur, arrived, removed the old SIM card, pressed the new one, and everything works!

★

Guest User2025-11-29

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.
