Esimify eSIM Data Plans for Japan

Esimify does not provide an unlimited‑data eSIM for Japan.
Instead, the provider offers fixed data plans that cover all of Japan on a 5G network. For example, a 20GB plan for 30 days costs $28.99 USD, a 10GB plan for 30 days costs $16.99 USD, and a 5GB plan for 30 days costs $9.99 USD. Choosing a fixed data plan can be more cost effective for most travelers unless they need a very high data allowance.

Esimify does not offer a Japan eSIM that includes a phone number or SMS capability. The provider’s Japan plans are data‑only, so travelers can use the internet through 4G or 5G but cannot make voice calls or send SMS using a local phone number. For voice and messaging, users can normally rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may block or restrict access to certain apps, so travelers should confirm that the services they need work in Japan before purchasing.

Esimify offers five single‑country data plans specifically for Japan and an additional five multi‑country plans that include Japan as part of a broader regional package. The single‑country plans provide data usage limited to Japan alone, whereas the multi‑country plans cover Japan plus other destinations, offering flexibility for travelers who need connectivity in more than one country. Prices for the options range from $2.99 to $88.99, with data caps spanning from 1 GB to 20 GB.
