eSIM Prime eSIM Data Plans for Japan

No, eSIM Prime does not provide an unlimited data eSIM for Japan. They offer a selection of fixed‑data plans, such as the Japan 20GB 1 month plan at $28.34 USD and the Japan 10GB 1 month plan at $15.74 USD, along with smaller options like the 5GB, 3GB, and 1GB plans. Choosing one of these fixed plans can be more cost effective unless a traveler expects extremely high data consumption. All plans come with 4G, 5G, and LTE coverage in Japan and allow tethering.

eSIM Prime does not provide a phone number or SMS capability on any of its Japan eSIM plans. All Japanese plans from the provider are data‑only, allowing you to browse the web, rent a Wi‑Fi hotspot, or use VoIP applications. Popular messaging and call services such as WhatsApp, Telegram, and iMessage work over a data connection and can replace traditional phone and SMS functions, but a native phone number is not included.

eSIM Prime offers five single‑country data plans for Japan. The plans range in price from $2.10 to $28.34 and provide data caps between 1 GB and 20 GB, with validity periods of 7 to 30 days. No multi‑country plans are available for Japan from this provider, and some of the single‑country options allow tethering.
