eSIM.sm eSIM Data Plans for Japan

eSIM.sm does not offer an unlimited data eSIM plan for Japan. The company’s available plans for Japan are fixed‑data options that range from 1GB for 7 days to 20GB for 30 days, all priced between $4.10 USD and $36.00 USD, with tethering allowed on each plan. For travelers who need a generous data allowance, the 20GB 30 days plan ($36.00 USD) and the 10GB 30 days plan ($18.50 USD) are the largest offerings and may be the most cost‑effective choice, unless the user is an extremely heavy data consumer.

eSIM.sm does not offer a Japan eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider. Travelers who need voice or text communication can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection.

eSIM.sm currently offers five data plans specifically for Japan. These plans provide data allowances ranging from 1GB to 20GB, with validity periods between 7 and 30 days. Plans are available at price points from $4.10 to $36.00. Tethering is permitted with some of the available options. eSIM.sm does not currently offer any multi-country plans that include Japan.
