Why an eSIM in Japan?
A travel eSIM for Japan keeps you online for maps, messaging, remote work or hotspot sharing, without hunting for prepaid SIMs at the airport. Keep your home number on the primary line and use the eSIM line for data. Pricing is transparent: pick GB and days, pay once, no subscription.
Tips before you go
Confirm your phone supports eSIM and is carrier-unlocked. Install the profile on Wi‑Fi at home, keep eSIM data off until you arrive, then enable data roaming on the eSIM line and turn off data on your home SIM to avoid surprise charges. If something fails, we can resend the QR from your order page or help on WhatsApp.
