merdata eSIM Data Plans for Japan

Merdata does not provide an unlimited data eSIM for Japan.
Instead, the provider offers fixed‑data plans that may suit most travelers. For example, a 50GB plan valid for 30 days costs $31.89 USD, and a 50GB plan valid for 180 days costs $53.22 USD. These fixed‑data options can be more cost effective unless a user requires extremely high data consumption.

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 provides a diverse range of eSIM options that include 15 single‑country plans and 50 multi‑country plans overall. While the dataset does not break down the counts by destination country, it indicates that within Japan users can expect a mix of both single‑country and multi‑country offerings. Plan types typically include fixed data amounts as well as daily data cap options, allowing travelers to choose between a set amount of data for the entire validity period or a daily allowance that resets each day. Prices across the catalogue span from about USD 0.94 to USD 104.29, and data caps range from 100 MB to 50 GB, giving customers a broad spectrum of choices for their data needs while traveling.
