ESIMFUN eSIM Data Plans for Japan

ESIMFUN does not provide any unlimited data eSIM plan for Japan. The available options are fixed‑data plans with caps ranging from 15 GB to 30 GB for a 30‑day validity period. For example, a 30 GB plan valid for 30 days costs $31.34 USD, while a 20 GB plan valid for 30 days costs $207.01 USD.

Choosing a fixed‑data plan can be more cost‑effective for most travelers, though users who consume a very high amount of data may need to compare prices across providers to find the best fit for their usage.

ESIMFUN does not offer a Japan eSIM that includes a local phone number or SMS capability. The provider only sells data‑only plans for Japan, so travelers do not receive a traditional mobile number to make regular calls or receive text messages.

Travelers can still communicate by using VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and provide voice and messaging functions without requiring a phone number or SMS service.

ESIMFUN offers 16 single‑country plans that are limited to Japan alone and 10 multi‑country plans that include Japan as part of a broader regional bundle. The plans cover a price range from $6.24 to $207.01 and data limits between 1 GB and 30 GB, with validity periods spanning 3 to 30 days. Among the offerings, 4 plans feature a daily data cap, meaning the data allowance resets every 24 hours, while 22 plans use a fixed data cap that is available for the entire validity period.
