TraveleSIM.CH eSIM Data Plans for Japan

TraveleSIM.CH does not provide unlimited data eSIM plans for Japan. The available options are fixed‑data packages. For example, a 50GB plan valid for 30 days is priced at $24.00 USD, and a 50GB plan valid for 180 days costs $38.00 USD. These plans offer a large data allowance but are not unlimited. Selecting a fixed‑data plan often offers a more cost‑effective solution unless the traveler requires truly unlimited data usage.

TraveleSIM.CH does not provide any eSIM plan that includes a phone number or SMS capability for travelers in Japan. All plans sold by the provider for Japan are data‑only and allow the use of mobile internet through 4G or 5G networks, but do not support inbound or outbound voice or text messaging. Travelers who need to make voice or text communications can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, as these services do not require a local phone number or SMS.

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.
