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

Guest User2025-12-25

Very convenient. The connection is stable. Thanks to the e-SIM, you don't have to constantly swap SIM cards between your local and local ones. I chose the 1GB/day plan. It's enough for uploading, browsing, and other small tasks.

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.

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!
