Convenient and easy to use. No problems with operation. Excellent signal reception throughout the trip. Data allowance matched the purchase order.

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 connected without any problems, and upon arrival in Vietnam, everything was activated. I had ten days of internet access: taxis, Google Maps, social media, calls, and video streaming. I recommend it to all my friends.

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.

That was really easy to install and use it. I was even able to use it on the island. Highly recommend 🔥
Reviews: Vietnam Viettel Local 5G eSIM | TikTok & ChatGPT Available | Daily 5GB | Calendar-Day Billing | QR Code

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).
