ESIM.DOG 🐶 eSIM Data Plans for Japan

ESIM.DOG does not provide a truly unlimited high‑speed data eSIM plan for Japan. All listed plans have a defined data cap, such as 10GB or 50GB, and after reaching the limit the speed is throttled (for example to 512 kbps). The plans are billed with a fixed data allowance that can be purchased for various validity periods.

If a traveler needs a large amount of data, ESIM.DOG offers substantial fixed‑data options, for instance a 50GB plan valid for 30 days or a 20GB plan valid for 30 days. These plans can be a more cost‑effective choice for moderate or heavy data use compared to attempting to use a plan with an “Unlimited” label that actually limits data after a set threshold.

ESIM.DOG does not offer a Japan eSIM that includes a local phone number or SMS capability. The provider’s Japan plans are data‑only. Travelers who need voice or text can use data‑based VoIP applications such as WhatsApp, Telegram or iMessage instead.

ESIM.DOG offers 128 single‑country data plans for Japan, with no multi‑country options available. The plans vary in price from $1.38 to $2, 694.36 and in data cap from 100 MB up to 50 GB. They include a mix of daily data cap plans—108 variants—and fixed data cap plans—20 variants—providing flexibility for different usage patterns.
