It's simple to set up and operate—just scan and play! The only drawback is that it cannot be used as a Wi-Fi hotspot for other devices, which I overlooked due to not reading the details. Despite this, I would definitely buy it again in the future.

Installation is a breeze—simply follow the steps provided in the email. Upon arriving at Haneda Airport, you can start using the eSIM right away. The signal is stable, offering fast and reliable connectivity everywhere. Highly recommended!

THis is the best offer on klook to purchase an eSIM when visiting Japan. Just simple to use; scan the QR code and follow the email's instructions. I took the 7 days plan . truly worthwhile. I activated the card 1 day before my departure. when I arrived, I turned off my primary card and set this card on. It seamlessly linked to the network. During my 7 days trip in Japan, it worked perfectly. Highly recommend if your phone is eSIM compatible.

Immediately received the QR code via email. Setup guide was likewise provided, although uploading of the QR via photos only work for Android. For IPhone, if you do not wish to enter the code manually, simply press and hold the QR code and an “Add eSIM” option will appear. Once you have uploaded the eSIM, it will automatically activate once you reach your destination. Connection and coverage has been reliable so far. Will likely use it again in the future.

e-sims are very convenient for solo travellers like me that always rely on google map. just activate the e-sims at least 6 hours prior to your flight. upon arrival i get a 4g connection all thru out my entire stay in Japan. NO DEAD SIGNAL even on top of the mountains (Murodo). HIGHLY RECOMMENDED

The eSIM card is the most cost effective and flexible way to roam around Japan without having to pay a hefty international roaming fees. I activated the card a day before my departure to Tokyo. when I arrived, I turned off my primary card and set this card on. It seamlessly linked to the local network. During my 5 days trip in Japan, it worked perfectly. Highly recommend if your phone is eSIM compatible.

eSIM makes it much easier to switch mobile networks. Instead of needing to order a new SIM, waiting for it to arrive, then inserting it into your phone, you can switch to a different network with a phone call or online. You also won’t need to go hunting for a SIM ‘ejector tool’ to remove the old SIM from your phone.
