eSimy eSIM Data Plans for Japan

eSimy does not provide an unlimited data eSIM plan for Japan. The provider offers fixed data allowance plans for travelers. For example, the “Japan - 50 GB - 90 days” plan costs $34.24 USD and includes tethering, while the “Global Explorer - 100 GB - 365 days” plan costs $342.53 USD and covers Japan and 106 additional countries. Choosing a fixed data plan such as these can be more cost‑effective for most users, though very heavy data consumers may prefer a higher‑cap option.

eSimy currently does not provide eSIM plans for Japan that include a phone number or SMS. Only data‑only offers are available in that market.

Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging, but some destinations might restrict access to these services. It is advisable to verify that the apps needed are accessible in Japan before purchasing an eSIM.

eSimy offers a portfolio of data plans in Japan that includes six single‑country options and ten multi‑country options. The single‑country plans cover only Japan, while the multi‑country plans allow the data to be used in Japan plus additional destinations. The plans span a price range from about $4.06 up to $348.66, with data caps that vary from as little as 1 GB to as much as 100 GB. Validity periods for the plans are between 7 and 365 days, and a number of the plans support tethering.
