eSIM4Travel eSIM Data Plans for Japan

eSIM4Travel does not provide a true unlimited data eSIM for Japan. The plans that carry the “Unlimited” name give 3 GB of high‑speed data per day and, after that limit is reached, the speed drops to 1024 kbps.

Instead, eSIM4Travel offers fixed data plans that can be more cost effective for most travelers. For example, a 50 GB plan for 30 days costs $50.35 USD and a 90 GB plan for 365 days costs $200.00 USD. These plans provide a set amount of high‑speed data without daily throttling, making them suitable for regular or moderate usage.

eSIM4Travel does not provide a phone number or SMS capability on its Japan eSIM plans; all available options are data‑only eSIMs. Travelers can still use the internet connection to access VoIP services such as WhatsApp, Telegram, and iMessage for voice calls and messaging.

eSIM4Travel lists 15 single‑country plans that cover Japan, and 16 multi‑country plans in which Japan is included. The provider offers both daily‑data‑cap options and fixed‑data‑cap options. Across the range, prices run from roughly $1.30 up to $200, data caps span from 1 GB to 90 GB, and validity periods vary between one day and one year.
