Good to know

  • An eSIM only works on a phone that supports eSIM. Airalo's check: dial *#06# in the phone app and look for a 32-digit number labelled "EID"; if it appears, the device supports eSIM.
  • The phone must not be carrier-locked. Airalo lists three conditions: the device supports eSIM, is not carrier or network-locked, and is not jailbroken (iOS) or rooted (Android). Ubigi likewise requires "an unlocked eSIM compatible device".
  • These travel eSIMs are data only. Ubigi states "Ubigi is a data-only service"; Sakura Mobile lists its travel data eSIM and SIM plans as "No phone number, data only" (it also sells a separate Voice + Data eSIM).
  • "Unlimited" plans have fair-use limits: Airalo's Japan unlimited packages drop to 1 Mbps after 3 GB per day; Ubigi's Japan unlimited plans include 30 GB (15 days) or 60 GB (30 days) at full speed, then 2 Mbps; Sakura Mobile caps hotspot use on its unlimited plans and slows its 3GB/day plans after 3 GB per day.
  • Airalo shows prices in the visitor's local currency, so the same package can show a different figure (for example yen instead of US dollars) depending on where the page is opened.
  • Sakura Mobile charges in Japanese yen only ("Prices in other currencies are for reference only"). It advertises its travel eSIM "from 1,250 JPY (1,375 JPY, tax incl.)" and travel SIM "from 3,500 JPY (3,850 JPY, tax incl.)"; the exact price depends on the dates chosen in its price tool.
  • Sakura Mobile pocket Wi-Fi can be collected at Narita, Haneda, Kansai, Fukuoka or New Chitose airport, at a local post office, or delivered to your accommodation, and returned in any postbox.
  • Ubigi one-off plans start on arrival in Japan and expire if not activated within 6 months of purchase. Ubigi's monthly (auto-renewing) Japan plans cannot be bought on its website, only in the Ubigi app or on ubigi.me.
