Cost efficient and reliable internet connection. There were just some areas where connection was patchy such as in some areas in Ba Na Hills. But this is understandable since it is on top of the mountain. It was also easy to connect, just bought the esim once we landed in Vietnam then immediately activated it on my phone.

We decided to use Klook’s eSIM for our Hanoi trip, and it turned out to be an excellent choice. The internet connection was consistently strong and reliable throughout the journey. The network provider was Viettel, which offered coverage almost everywhere we went, except for a few stretches along the highway. I was able to navigate easily using maps, browse social media, and watch YouTube videos without any issues. Activation was straightforward, and having immediate access to data upon arrival made travelling around Hanoi much more convenient. Overall, it was a smooth and hassle free experience. Highly recommended for anyone travelling to Vietnam, and I would definitely use it again for my next trip.
