ESIMFUN eSIM Data Plans for Japan

ESIMFUN does not offer an unlimited data eSIM for Japan. All available plans list a specific data cap, with the largest being 30 GB for a 30‑day validity at $31.26 USD.

Travelers who need data in Japan can choose from fixed‑data options such as the 30‑day 30 GB plan at $31.26 USD or the 30‑day 15 GB plan at $20.93 USD. A 30‑day 20 GB plan at $206.48 USD is also available, providing coverage in Japan plus 95 other countries. Fixed‑data plans can be more cost effective unless a user expects extremely heavy data consumption.

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 sixteen single‑country data plans that cover Japan, and ten multi‑country plans that include Japan among their destinations. The available plans vary in price, with rates ranging from about $6.23 up to $206.48, and data caps spanning from 1 GB to 30 GB. The pricing and data limits are presented in a single‑day or multiple‑day validity period of 3 to 30 days, and plans come in both fixed data amounts and daily‑cap varieties.
