The installation method was easy to understand, and setup was smooth. Communication was comfortable throughout the trip, and I was able to use it without any issues. However, the "Asia eSIM" I purchased this time included Japan as a covered country, so the usage period and validity countdown began as soon as I installed it in Japan. I failed to check this detail, and the validity period expired during my trip. Afterward, I purchased additional country-specific eSIMs for Thailand and Cambodia. They were very affordable and I could use them immediately, which allowed me to continue my trip with peace of mind. Next time, I will check the covered countries, and if Japan is included, I plan to install it on the day of departure or at the airport. For others in a similar situation, just being aware of this point will save you trouble. The product itself is very easy to use, and I would like to use it again.

I was able to use it without any problems in Siem Reap, Cambodia! If your home country is included in the coverage, pay close attention to the activation date and time! Days are counted starting from the moment of activation!

It was incredibly convenient for traveling around Asia. While buying individual tickets for each country I wanted to visit might have been slightly cheaper, opting for a multi-country itinerary eliminated the hassle of making separate arrangements, making it stress-free. I traveled from Hong Kong to Hanoi, then Da Nang, and back to Hong Kong, and after considering various options, choosing this plan was definitely the right decision to avoid the setup effort. The signal was almost always good; there were times my wife, who had the same plan, connected to a different carrier, but it wasn't an issue. We had no problems even in remote areas like My Son Sanctuary and Ha Long Bay, and it even connected while at sea.
