Reviews: Vietnam Viettel Local 5G eSIM | TikTok & ChatGPT Available | Daily 5GB | Calendar-Day Billing | QR Code

This is my first time using an eSIM. I scanned the QR code before boarding the plane, turned it on upon arrival, and everything worked perfectly every day. The signal is excellent everywhere, no complaints whatsoever. I shared the internet with my husband; 3 GB was perfectly enough for both of us per day.

There were very rare network drops and loading times were long, but after switching to flight mode and back, everything immediately returned to normal.

Before buying a local SIM card, I purchased this service. Overall, everything installed and worked without any issues. It was more of a problem with the location we were in (Phu Quoc Island)—the internet was quite slow, even on 5G.

Excellent! We reserved two e-SIM cards in Russia and paid with a Russian card. Upon arrival in Vietnam, we connected to Wi-Fi at the airport and connected in just one minute using a QR code. The connection quality is very stable, and we can share it. Super convenient and easy! Thank you!

This is my second time buying it. It's very convenient. All the settings are configured automatically. You arrive and it works right away. The only thing I had to do was reboot my phone.
