eSIM.sm does not provide an unlimited data eSIM for Japan; all plans are limited to a fixed data allowance. Travelers who need more data can choose from several prepaid options that have large volumes of data. For example, eSIM.sm offers a 20GB plan valid for 30 days at $40.00 USD and a 10GB plan valid for 30 days at $21.20 USD. These fixed‑data plans can be more cost‑effective for most users unless the traveler is an extremely heavy data consumer.
eSIM.sm does not offer any Japan eSIM plans that provide a phone number or SMS capability. All Japan eSIMs sold by eSIM.sm are data‑only, so you will not receive inbound or outbound voice or text services. If you need to communicate while traveling, you can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.
