merdata eSIM Data Plans for Japan

Merdata does not provide an unlimited data eSIM plan for Japan. Travelers who need higher data allowances can choose from the fixed-data options available. For example, the eSIM Japan 50 GB 30 days plan costs $30.56 USD and the eSIM Japan 50 GB 180 days plan costs $51.01 USD. These fixed plans may be more cost‑effective for most users unless extremely heavy data consumption is required.

Merdata does not provide Japan eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available from this provider for travel to Japan.

Travelers who need to make voice or text communications can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on will work in Japan before purchasing a plan.

Merdata offers 16 single‑country plans and 50 multi‑country plans that include Japan. The available packages feature fixed data amounts ranging from 100 MB to 50 GB, with validity periods between 1 and 365 days. Prices for Japanese coverage start around $0.92 and can go up to about $102, depending on the chosen data allowance and duration. No additional plan types such as daily caps or roaming‑only options are listed in the data.
