Business travel
A work trip has two problems a holiday does not: staying reachable on your home number, and feeding a laptop. Both have clean answers.
Our eSIM carries all data on KDDI 4G and 5G. Your home SIM stays on for calls, texts and bank codes with its data off. You keep your number, and nothing roams by accident.
A laptop on video calls eats data, so we steer that buyer away from our own unlimited plan: its flat 10 Mbps cap suits phones, not workdays. Take 20GB across 15 days at $21.84, the live catalog checked October 22, 2026, or 20GB across 30 days at $22.89, and run heavy meetings on hotel Wi-Fi. Most plans allow hotspot; each plan's rule is printed at checkout.
Phone-first work week: 10GB for a week at $12.44. Monthly rotation: 20GB across 30 days covers the whole stay for less than one taxi in from Narita.
Stripe emails the card receipt within minutes, issued against Fizen LLC. Need more for your expense system: reply to the order email and a human sorts it.
Install on office Wi-Fi, set the data line, done. Exact taps for both platforms are in the install guide below.

Yes, a Stripe card receipt by email within minutes of paying, issued against Fizen LLC. For anything your expense system needs beyond that, reply to the order email.
