Reviews: Japan SoftBank 4G/5G eSIM | TikTok & ChatGPT Available | Day Pass | 24-Hour Billing | 1-30 Days | QR Code
Guest User2025-12-06
The internet is okay, but the signal is weak in some areas in Kyoto. We bought 2GB per day, but it wasn't enough. Every day, it runs out at 5 PM. After it runs out, it's incredibly slow, making it almost impossible to do anything. If you're using it a lot to browse maps, use Instagram or TikTok, I recommend 5GB per day. It's better to have some extra than not enough, because it can be really difficult to search without internet.★

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.★

This time I traveled to Takamatsu alone. I installed the device beforehand, and after landing, I turned off flight mode and immediately got a signal. The signal was also good during my island hopping trip in Takamatsu, even though it was a bit pricey.★

I visited Takamatsu. I stopped by Naoshima, Kurashiki, and Kotohira Shrine. The speeds were comparable to those in Korea, so I used it comfortably. Sometimes, the speeds get significantly weaker when going uphill or underground, but that's to be expected. If you purchase this upgrade, you'll have a comfortable trip.★

Guest User2025-12-12
Using an eSIM card abroad is incredibly convenient. Activation is quick; simply scan the QR code to access the internet immediately, without needing to replace the physical SIM card. The network speed is stable, and the signal is excellent, making navigation, information retrieval, and contacting family and friends smooth sailing. Throughout the entire trip, there were no dropped calls or delays, making for a very satisfying experience. For frequent international travelers, eSIM is truly a lightweight and practical choice. I will definitely use it again on my next trip abroad and will recommend it to my friends and family!
