SIMDUCK.COM eSIM Data Plans for Japan

SIMDUCK.COM does not provide an unlimited data eSIM for Japan. All of its Japan‑specific plans have a fixed data cap, with the largest offering 50GB of high‑speed data.

Travelers who need a large data allowance can choose from SIMDUCK.COM’s fixed data plans, such as the Japan 50GB plan valid for 30 days or the Japan 50GB plan valid for 180 days. These options give a clear data limit and validity period, which can be more cost‑effective for most users unless they require truly unlimited data.

SIMDUCK.COM does not offer an eSIM plan that includes a phone number or SMS capabilities for Japan. All eSIM options sold by SIMDUCK.COM for Japan are data‑only plans without inbound or outbound voice or text services.

Travelers who need to make calls or send messages while in Japan can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but these services may be subject to local restrictions. It is advisable to check the accessibility of the specific applications you plan to use before purchasing a plan.

SIMDUCK.COM offers a total of 37 data plans for Japan, consisting of 28 single‑country plans and 9 multi‑country plans. These plans span a price range from about $1.99 to $118.99 and a data capacity range from 100 MB up to 50 GB. The single‑country options allow travelers to stay within Japan with a set amount of data (fixed‑data plans) or a daily data cap depending on the selected package.

Both sets of plans keep validity periods between 3 and 180 days and often include features such as tethering and optional speed reductions.
