I bought a SIM card while the airport Wi-Fi was working. It took me a minute. It took another two minutes for the SIM card to install itself and connect to my phone 📲. 5G internet was available immediately. The speed was excellent throughout the entire trip 👍

Excellent. Internet is available throughout the island. This conclusion is based on the GPS in the rental car.

Just finished a 9-day trip across Vietnam and the Viettel eSIM was flawless. I had a strong signal everywhere—from the busy streets of Hanoi to the more remote areas. The setup was instant via QR code, and the speeds were fast enough for maps, grab bookings, and social media uploads without any lag. If you want a "set it and forget it" data plan, this is it. Highly recommended!

The sim card is easy to install (in-app). The internet is fast enough. For me the 9gb plan was enough for both: work and personal stuff.

Throughout our trip, the signal speed was excellent in various locations including Da Nang city, My Khe Beach, Marble Mountains, Son Tra Peninsula, Hoi An, and more. The only place we experienced poor signal was inside a restaurant outside Hoi An Ancient Town. (However, this was the same for our Trip eSIM, other travelers' roaming devices, and other eSIM providers.)
