Reviews: Japan SoftBank 4G/5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | QR Code
Guest User2026-04-23
After booking, you'll receive a QR code for installation. Installation is easy. Once in Japan, connecting to the signal is easy, and the speed is stable. We used 5GB a day and had plenty left over (but we didn't use it for maps). It's easy to use for general purposes and we had no problems at all. The kids used it to play games and watch cartoons all day without any issues. It's great, I highly recommend it.

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

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 au KDDI 5G eSIM | Unlimited Data | TikTok & ChatGPT Available | Calendar-Day Billing | QR code
Guest User2026-04-23
It's very convenient. I bought it, received a code by email, activated the SIM card, switched on the eSIM when I arrived in the country, and was instantly online. The internet speed is good, and I had a connection everywhere. The downside is that it only includes a data plan; outgoing calls and text messages are unavailable. But if you really need it, you can buy a SIM card once you're in the country. I recommend this service; it's very convenient and relatively inexpensive!

Reviews: Japan 5G eSIM | Daily/Total Package | 500MB/day - 30GB total | 1-30 days | QR code
Guest User2026-04-23
I used this eSIM during my trip and it worked perfectly. The installation process was very straightforward with the QR code. I was able to use maps, upload photos, watch videos, and stay active on social media without any major issues. The connection was stable and the speed was good enough for everyday use. It really made traveling more convenient.
