During my trip to Vietnam, the reception and network speed of Viettel's eSIM in Ho Chi Minh City, Binh Duong, and Tay Ninh were quite stable and satisfactory. eSIM is really convenient because you don't need to insert and remove a physical SIM card anymore. Installation is easy and user-friendly. Highly recommended! 👍
We used the premium plan for a family trip (5 people). The total cost was about 22,000 yen. I don't think there's any benefit to the premium plan. (The regular plan seems fine.) December 27, 2025 Arrived at the airport at 1:00 PM local time. After completing check-in (1:45 PM), we met with the staff. We were able to depart the country just after 2:00 PM. There were fewer passengers than when we entered the country. Usually
Took us about 30 minutes to clear with basic line. Acceptable considering the usual line was very long. Would have taken at least an hour without fast track.
The eSIM performed well in Ho Chi Minh City, with 5G signal available in most areas. Ride-hailing and Instagram worked smoothly. I didn't specifically test video streaming, but it was more than enough for my daily internet needs.
