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: KDDI Japan 5G Local eSIM | Daily Package | 100GB/day | 3-26 days | QR code

On this trip to Japan, I tried an eSIM and I can honestly say my life improved by 300%! 🛫📶 No more searching for a SIM card at the airport, no more unpacking a SIM card, no more worrying about losing it. Just scan the QR code before flying, and as soon as you land…the internet is instantly there! ✨ The signal was incredibly stable. Even when I got lost in Tokyo, I could still use Google Maps smoothly and upload stories non-stop. Anyone who creates content will love it! What I liked most is that I didn't need to carry anything extra; one device did it all.

I had no problems using this eSim in Nagoya, Okazaki and Matsumoto. It was a breeze, and I never lost access to the internet, which was super important as we were navigating the roads while driving, and really depended on Google Maps to get to all our destinations through the rural areas as well.
