It worked great throughout the trip and was very economical. You should study the instructions carefully, or ask friends who have used it before, to ensure you use it correctly and without problems.

I added the map in advance, a few days before my flight, and activated it immediately upon arrival in Hanoi. There were some minor speed issues at Hanoi Airport before baggage claim and on the way from the airport to the city, and the connection dropped a couple of times on the highway. Otherwise, the signal was stable, even when going out to sea on an excursion. I used the map on the route Hanoi - Halon - Da Nang - Nha Trang - Phu Quoc - Ho Chi Minh City, and it worked without any issues throughout.

For my trip to Hanoi, Vietnam, I purchased a 10-day, 20GB e-SIM. The deciding factor was that it was a China Telecom product, which I had used before. I completed the e-SIM activation in Japan, and while waiting for my checked baggage at Hanoi airport, I switched the SIM, manually set the APN, and after turning airplane mode on and off a couple of times, the connection worked immediately. I was able to maintain a stable connection not only in Hanoi city but also while traveling to Sapa and on the bus during my Ha Long Bay cruise. Incidentally, the smartphone I used was a Sharp AQUOS sense 10. If you are using a Japanese Android smartphone, you will likely need to manually set the APN, so you should familiarize yourself with that procedure, but I was able to use it comfortably in Vietnam.

It's very convenient that you don't have to scan the code for each country; just reboot your connection and, if it can't find your connection, use the network search. The speed is excellent, and you can access Instagram and other sites without a VPN.
