I only saw later that Trip.com offered something like this. I bought the 5G package and was "relatively" satisfied. Sometimes there were problems with no signal, so I had to use my other eSIM and could switch back and forth. Nevertheless, I was satisfied and would buy it again next time.

[Super Stable Signal and Extremely Fast Speed ​​While Traveling in Fukuoka – A Perfect eSIM with Easy Setup!] During my recent trip to Fukuoka, Japan, I decided to try out this KDDI 5G eSIM, and the experience was truly satisfying! 1. Super Convenient Setup and Activation: I quickly received the QR code via email after ordering. Before leaving, I scanned the code in Taiwan to set it up. Upon landing at the Japanese airport, I turned it on, switched mobile plans, and immediately connected to the internet. No need to change the physical SIM card – incredibly convenient! 2. Network Speed ​​and Signal Performance: Whether riding the subway, shopping in Hakata and Tenjin, or visiting more distant classic attractions (like Fukuoka Tower and Momochi Seaside Park), the network speed was consistently fast. Watching high-definition videos, checking maps, and posting photos on social media were all smooth without any lag. As a major Japanese telecom operator, KDDI's 5G signal coverage is truly excellent, remaining stable even indoors and in underground shopping malls. 3. Ample Data Capacity for Peace of Mind: With plenty of data available every day, there's virtually no need to worry about running out of bandwidth. The entire trip was an excellent experience. I will definitely repurchase this next time I'm in Japan. Highly recommended for travelers looking for a convenient, high-speed data SIM card!

The stable connection speed made it very easy to use. I was able to smoothly watch videos, use social media, and browse the internet without interruptions or long loading times, making it a very comfortable experience. The stable connection, especially when I was out and about, was incredibly convenient, allowing me to use it anywhere. I was also able to use online calls and video streaming services without any problems, which has been useful not only in daily life but also for work and hobbies. The good connection environment reduced stress and allowed me to use the internet with peace of mind, which I found to be a major advantage. Furthermore, app downloads and updates were completed quickly, minimizing waiting times and making it efficient. Not having to worry about data limits is also a huge help. Compared to my previous internet service, I'm very satisfied with the speed and stability, and I use it comfortably every day. Overall, I found the internet connection to be extremely user-friendly and a service that makes everyday life much more convenient. I'm so satisfied that I want to continue using it.

It was a very interesting trip to Japan, but I probably won't be going back anytime soon. My company's project there for this year has been successfully completed. Thanks to Ctrip for recommending the SIM card, the speed is so fast!
