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

Guest User2026-02-13

Very easy to use, convenient, and the internet signal is good with no problems. The price is also very cheap. I registered the eSIM in Thailand and was able to activate it as soon as I arrived in Vietnam.

★

Guest User2026-02-13

I got two eSIM cards, activated one from the airport, and shared the other using tethering. For daily use, I got the 2 GB/day plan, which was more than enough. Everything works flawlessly.

★

Guest User2025-07-27

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!

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

Guest User2026-01-11

I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.
