Loved by first-time travelers.

Canada trip

Not tech-savvy at all, but it worked in about a minute — I was amazed. I reached my friends abroad right away.

Rinsuke M. · Man, 20s · Canada

Korea trip

LINE and maps worked the moment I landed, and I could look up shops on the spot. Easier than renting Wi-Fi — easy even for a first eSIM.

Mizuki S. · Woman, 20s · Korea

Singapore business trip

I used an unlimited plan for business. I checked email right after landing and tethered my PC on the move. No need to watch my data while working.
