Jett-On eSIM Data Plans for Japan

No unlimited plans are offered by Jett‑On for Japan. The network provides several fixed‑data packages instead.
Among the larger options, the 30GB 30 days plan runs at $111.00 USD, while the 20GB 20 days plan is $83.00 USD. These higher‑capacity plans are generally more economical for users who require a substantial amount of data, but travelers who use an exceptionally high volume of data may find that an unlimited plan would be more cost‑effective.

For travel eSIMs in Japan, Jett‑On does not provide a local phone number or SMS functionality. All of Jett‑On’s Japan eSIM plans are data‑only, so there is no built‑in voice or text messaging service. Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

Jett-On currently offers six single-country data plans specifically for Japan. These plans range in price from $9.00 to $111.00 and provide data allowances between 1GB and 30GB. There are no multi-country plans available from Jett-On that include Japan as one of the covered countries. Some plans allow for tethering.
