The SIM card worked perfectly throughout my trip. Internet speed was fast and stable, even in remote areas. Easy to activate and great value for money. Highly recommended!

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.

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!

Super convenient and cheap! Viettel is definitely the way to go when traveling to Vietnam and Phu Quoc! The signal is consistently excellent and stable. Just set it up, and you can connect as soon as you get off the plane, plus the speed is fast! Compared to the other physical SIM cards my husband bought (which had terrible signal, even at full bars it was slow), my eSIM was the only one with a stable signal among the four of us 😂 I was responsible for creating a hotspot for the family. The internet speed test was very fast, reaching over 800Mbps (don't test it unnecessarily, it consumes a lot of data).

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.
