FullBars eSIM Data Plans for Japan

FullBars does not provide an unlimited data eSIM plan for Japan. Their current Japan offerings are fixed‑data packages. For example, the Japan 50GB · 30 days plan delivers 50GB of high‑speed data for 30 days, priced at $35.90 USD, while the Japan 20GB · 30 days plan offers 20GB for $17.28 USD. These fixed plans can be more cost‑effective for travelers who are not heavy data users, as they give a clear quantity of data at a set price over the plan’s validity period.

FullBars does not offer any Japan eSIM plans that include a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from this provider. However, standard VoIP services such as WhatsApp, Telegram and iMessage can generally be used over the data connection for calling and messaging. Because some destinations may block or restrict certain applications, users should confirm that the apps they rely on are functional in Japan before making a purchase.

FullBars offers a total of 16 distinct data plans for travelers heading to Japan. Six of these are single‑country plans that can be purchased solely for Japan, while ten are multi‑country plans that include Japan as part of a broader regional package. The plans cover data caps from 1 GB up to 50 GB and are priced between roughly $2.65 and $188.84, depending on the duration, data amount, and whether the plan is a fixed‑data package or a daily‑cap option. This range provides flexibility for short‑term stays or extended travel across multiple countries.
