TraveleSIM.CH eSIM Data Plans for Japan

TraveleSIM.CH does not offer an unlimited data eSIM for Japan. Every plan listed has a fixed data cap. The largest available caps are 50GB, with smaller options such as 20GB.

Travelers who need high‑volume data can choose fixed‑data plans such as the 50GB plan valid for 30 days, priced at $23.31 USD, or the 50GB plan valid for 180 days, priced at $36.91 USD. A 20GB plan for 30 days is also available for $12.63 USD. Using a fixed‑data plan may be more cost‑effective unless the user requires unlimited usage.

TraveleSIM.CH does not provide a phone number or SMS capability for its Japan eSIM plans; only data‑only subscriptions are available. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though the accessibility of these apps can vary and some destinations may block or restrict certain services. It is advisable to confirm that the applications required for communication are usable in Japan before purchasing a plan.

TraveleSIM.CH provides 21 single‑country data plans and 40 multi‑country plans that include Japan. Plans come in two main styles: fixed data packs that deliver a set amount of data (ranges from 1 GB to 50 GB) and daily‑cap offers that allocate a specific data allowance for a single day or a few days. Prices for the Japan‑focused plans span from $2.47 to $117.65, giving a broad range for both short‑stay travelers and visitors on longer trips.
