Installation is quick and easy. Simply scan the QR code on your phone to add the service beforehand, and you can connect to the network as soon as you arrive at your destination. The 3GB high-speed data per day is more than enough; in actual use, it's around 2GB per day.

My Fukuoka trip was seamless! Checking train schedules was easy, the internet was strong, and I could post on social media non-stop. The internet was great, no interruptions at all. All apps worked perfectly, and the signal was good everywhere – trains, malls, tunnels – I was very impressed! 🤩 The price was also very affordable, and the eSIM was super easy and convenient to install.

I tried using an eSIM on my recent trip to Japan, and it was incredibly convenient! I loved being able to install it in advance and use it immediately upon arrival without having to swap my SIM card. The internet speed was fast, so I experienced no inconvenience searching for maps, finding restaurants, or uploading photos. I definitely want to use it again on my next trip to Japan! 😊

I spent 7 days in Hokkaido, and the internet connection was smooth and convenient throughout. I installed it with one click before departure, and the connection was immediately available after logging off. If the connection wasn't immediately established after logging off, try restarting your computer. Also, if you've used an eSIM while traveling elsewhere, remember to delete the old eSIM before installing the new one; otherwise, you might experience a false signal but be unable to connect.

Smooth and seamless experience. Very easy registration. Fast and strong internet connection throughout. Much better price than other places. Truly worth it. I've used it in China before, and this is my second time using it in Japan.

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!
