eSimy eSIM Data Plans for Japan

eSimy does not provide an unlimited data eSIM plan for Japan. Their offerings in Japan are fixed‑data packages such as the Global Explorer plan that includes 100GB of data for 365 days and costs $347.57 USD, the Global plan that offers 25GB for 365 days at $86.90 USD, and the Japan‑specific plans that give 20GB for 30 days at $28.95 USD or 10GB for 30 days at $24.32 USD. Choosing a fixed data plan can be more cost effective for most travelers unless the user is an extremely heavy data consumer.

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.
