FullBars for Japan FAQ

Does FullBars offer unlimited data eSIM for Japan?

FullBars does not provide an unlimited‑data eSIM plan for Japan. All of the plans available for Japan are fixed data bundles with a set allowance and validity period.

Travelers can choose from several large‑data fixed plans, such as the Japan 50 GB · 30 days plan priced at $36.10 USD or the Japan 20 GB · 30 days plan at $17.37 USD. These plans offer high‑speed 5G coverage across Japan, but each has a hard data cap and a 30‑day validity window. For users who need more data or a longer period, other fixed bundles or a pay‑as‑you‑go option are available, although they also have explicit data limits.

Does FullBars offer Japan eSIM with phone number and SMS?

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.

How many data plans does FullBars offer for Japan?

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.
