Earth Esim eSIM Data Plans for Japan

Earth Esim offers a range of unlimited data eSIM plans for Japan that run on 5G networks. Validity periods start at 3 days and extend up to 31 days, with prices ranging from $10 for the shortest plan to $75 for the 31‑day option. Each plan allows tethering but notes that speeds may be throttled after extended use, indicating a Fair Usage Policy.

Under this policy, a user’s speed could be reduced after heavy data consumption, although the plan remains unlimited in data volume. Travelers who are unsure about the exact Fair Usage limits or how much data remains available at normal speed are encouraged to contact Earth Esim directly for clarification.

Earth Esim does not provide any eSIM plan for Japan that includes a phone number or SMS capability. Their Japan offerings are data‑only, with no voice or SMS services. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

Earth Esim provides 32 single‑country plans that include Japan and 21 multi‑country plans that cover Japan together with other destinations. The available plans span a price range from about $0.79 to $159.00, with data caps that can go from 500 MB up to unlimited, and validity periods covering from 1 to 180 days. Some plans feature a fixed data amount for the entire validity, while others offer a daily data cap that resets each day; both options can be chosen depending on the traveler’s usage pattern.
