Used a SoftBank 4G eSIM while traveling around Tokyo and Fujikawaguchiko, and it worked great. Setup was easy, and the connection was stable the whole time. Speeds were good for maps, messaging, and socials, even outside the city. Super convenient and reliable for Japan travel.

This was our second time purchasing this eSIM, and it never disappoints! It worked perfectly everywhere we went and made our trip so much easier especially when using Google Maps for navigation. Definitely a must-have when traveling in Japan! We’ll absolutely buy it again when we come back!

Lovely way to have internet throughout your entire trip in Japan! I experienced little to no connection issues. The only ones I had were in the most remote areas, which is to be expected, but all this meant was a little less faster internet. Being able to use this as a hotspot was also a lifesaver as me and my partner would both be able to use the internet.

Using the 4G eSIM for Japan from Softbank was a game-changer for our trip! The setup was quick and easy—after receiving the QR code via email, we simply scanned it, and we were connected within minutes. The signal was strong throughout our travels, and we never experienced any issues with coverage. It was super convenient not having to worry about physical SIM cards or finding local Wi-Fi. The eSIM was reliable and made staying connected during our trip effortless. Highly recommend this service for anyone traveling to Japan!

This eSIM is hands down one of the most reliable and efficient solutions we’ve ever used. It never let us down—always working seamlessly, even in busy areas like Osaka. We relied on it heavily for Google Maps, and it consistently delivered, making our navigation and overall experience much smoother. Highly recommend it!

E-sims are easy to use! It helped us a lot as having our own internet data during the trip is a must - for checking train operating times, where to eat, what to buy and of course navigating GOOGLE MAPS! 🤩🥳 Thanks Klook!

As it was our first time using an eSim, we were unsure if we did the right procedure for the installation. Good thing it did work once we landed in our destination. The signal was good, it kept us connected while travelling. However, there were times when we lost the connection. Probably because of the location. Anyway, everything went well.
