I bought an eSIM card, but I got the period wrong. I easily bought more days, and I didn't have to reinstall anything. I always had internet, and I'm very happy with the quality and price.

Guest User2026-01-13

Absolutely amazing! We used an e-SIM for the first time. We installed it before the trip, and everything worked immediately upon landing and throughout Fukuoka. We really liked it. Until we bought a local SIM card for the long haul—the 100% option.

Guest User2025-11-24

That was really easy to install and use it. I was even able to use it on the island. Highly recommend 🔥

Guest User2026-01-15

I activated my ESIM at the airport using a QR code. It was quick and easy, following the instructions provided. Internet was available immediately after landing, within 3-5 minutes. I didn't use customer support. The internet connection was good, but there were a few times when search pages wouldn't load. The 2GB of daily data was enough for chatting, sharing photos, searching for information, and using maps.

It was easy to install and worked well. Sometimes esp in countryside was not working well. Overall is good

Guest User2025-11-29

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.
