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.

Worked well, easy to install and activate on landing. So much cheaper than the bigger named one we used last year in Japan. Will use Trip for our eSIMs in future now, having had one for Korea and one for Japan without any problems on the latest trip. Great price.

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.

Didn't realise how easy this is! From the purchase to the information on how to set up, amazed how simple it is. Then the mobile reception and coverage is high quality and all using your own phone.

I couldn't activate it right away. Support responded quickly and the problem was resolved (I just had to wait). The signal quality and internet speed were excellent throughout the entire trip!
