eSimpli eSIM Data Plans for Japan

eSimpli does not have a true unlimited data eSIM for Japan.
The plans that carry the “Unlimited” name give 1 GB per day, and once that daily allowance is used the speed is throttled to 1250 kbps. For travelers needing more high‑speed data, eSimpli offers fixed‑data plans such as the 20 GB 30‑day or 10 GB 30‑day options, which deliver the full data amount without speed reduction for the entire validity period. These plans are typically more cost‑effective for typical data usage, while the “Unlimited” plans may suit those wanting a larger daily allowance but accepting the reduced speed after the 1 GB threshold.

eSimpli does not offer any Japan eSIM plans that include a phone number or SMS capability. Travelers who purchase an eSimpli eSIM for Japan will receive a data‑only plan only. Voice and text messages can still be sent through popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may restrict or block access to these services, so travelers should verify that the apps they rely on are available in Japan before buying a plan.

eSimpli offers 9 single‑country data plans for Japan and 5 multi‑country data plans that include the Japanese market. The plans are priced between roughly $8 and $110, with data caps ranging from 1 GB to 20 GB. Some plans provide a fixed amount of data that remains available for the entire validity period, while other plans offer a daily data cap that is refreshed every day.
