Reviews
I bought the unlimited internet data. The internet is very strong- I went to Kansai region(Nara, Kyoto, Osaka) and also to Setouchi to Takamatsu and off islands. Specifically want to highlight that even on the islands like Naoshima, Megijima, Ogijima, Teshima… all have very good connection! Highly recommend!
I used this for my 7 days stay in Japan. I roam around Osaka, Kyoto, Nara and Shiga and the connection was good. The only time the signal is bad was when we are at Biwako Valley but that's understandable because it is on top of a mountain. Overall good experience and I will use this again on my stay next time in Japan.
We booked the 6-day 4G/5G unlimited data Japan eSIM through Klook and it worked well throughout our trip. We used it in several areas including Fukuoka, Yufuin, Nagasaki, and Miyazaki, and overall the connection was reliable and easy to use. There were a few moments when the internet signal became weak, especially during train rides through countryside areas, but this was expected and did not affect our overall experience. For most of the trip, the eSIM worked smoothly and allowed us to stay connected for maps, messages, and browsing. Just make sure that your phone supports eSIM before purchasing. We used a Samsung Galaxy S24 Ultra and an iPhone 13, and both devices worked perfectly with the eSIM. Overall, this eSIM is a convenient and hassle-free option for travelers to Japan who want unlimited data without carrying a pocket WiFi.
The internet was fast. I had no problem connecting to the internet and using it all around Japan. Make sure to turn on data roaming so you will have data and can use it. Very convenient.
I bought the Japan 4G/5G eSIM through Klook and it worked great during my trip. The activation was fast and simple — just scan the QR code and it connects right away. Mobile data was stable in Tokyo, Shibuya, Shinjuku, and even on the subway. Speeds were good for maps, social media, and video calls. Overall, it’s a convenient and affordable option for tourists who want reliable internet without needing a physical SIM card.
The entire experience was seamless. Activation was quick and effortless—just scan the QR code, and you’re instantly connected. The data speeds were fast and reliable everywhere we went. It was especially convenient not having to swap out my physical SIM card or worry about finding a local store after landing.
Great eSIM experience! The setup was quick and straightforward, and the connection was stable throughout my trip. Data speeds were reliable for navigation, messaging, and browsing, and I had no issues activating it upon arrival. It was very convenient not having to buy a physical SIM card. Highly recommended for hassle-free travel connectivity!
Activating the esim is easy and using it was very helpful. My 3 friends used it while they are connected to me thru personal hotspot and still the connection is fast. Highly recommended. I will definitely use and purchase it again. Made my travel easy and still connected while I’m busy strolling around the city and different tourist attractions.
used this esim several times now and it worked in places like tokyo, kanagawa, wakayama, shizuoka, kyoto, osaka, and nagoya. data is just limited during train rides in the province but otherwise it’s effective everywhere i went
This eSIM made my trip so much easier. Setup was very simple — I installed it before arrival, and it activated smoothly once I landed in Japan. The connection was consistently fast and reliable across multiple cities. I used it heavily for Google Maps, train schedules, restaurant searches, and uploading photos, and it never disappointed. No need to carry a pocket WiFi device or swap physical SIM cards. It was convenient, stable, and great value for money. I would absolutely purchase this again for future trips to Japan.
