Misaki Tanaka
20s / Shanghai, China (4 days, 3 nights)
I used the unlimited plan in China. It was very convenient to use the internet comfortably without needing a VPN. The setup was easy, and even though it was my first eSIM, I had no problems at all.
Kenta Sato
30s / Asia Tour (2 weeks)
I traveled through Thailand, Vietnam, and Singapore. It connected automatically even when I changed countries, which was very convenient. I could also use tethering, so checking work emails went smoothly.
Yumi Suzuki
40s / Seoul, South Korea (4 days)
We used it for a family trip. The kids were very happy being able to check maps and upload photos to social media on their phones. Having 24-hour support was also reassuring.
Daisuke Yamamoto

It was my first time using an eSIM, but I could set it up easily just by scanning the QR code. The speed was fast with 5G support, and I could use it without any stress. I will definitely use it for my next trip.
