Misaki Tanaka
20s / Shanghai, China (4 days, 3 nights)
I used a daily plan in China. It was so convenient to use the internet comfortably without needing a VPN. The setup was easy, and even though it was my first time using an eSIM, I had no issues 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
50s / Taipei, Taiwan (5 days)
This was my first time using an eSIM, but it was very easy to set up just by tapping the quick link in the email. With 5G support, the speed was fast and I could use it without any stress. I’ll definitely use it again on my next trip.
