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.

Reviews: Japan SoftBank 4G/5G eSIM | TikTok & ChatGPT Available | 24-Hour Billing | 1-30 Days | QR Code

Guest User2025-12-30

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.

★

Guest User2026-02-20

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

★

Guest User2026-03-03

Nice, the line was good and reliable even in the train. Definitely recommended to anyone who needs an eSIM in Japan.

★

Guest User2026-03-04

I used a eSIM during my trip and it worked flawlessly. Setup was quick and straightforward, and I had stable connection throughout the city. Speeds were fast enough for maps and streaming. Super convenient, no need to swap physical SIM cards.

Guest User2026-03-06

The esim was really good, the signal was always strong everywhere I went to, some places are pretty high and far away like Togakushi Shrine, Shibu onsen … but I never had any problem with the signal, I bought 2 sim cards, 1 is unlimited and the other is 2gb/day but I felt like I never ran out of data even with the 2gb one haha
