FootySIMs eSIM Data Plans for Japan

FootySIMs does not provide a truly unlimited data eSIM for Japan. The only plan branded “Unlimited” actually offers 1 GB per day and reduces speed to 512 kbps once that amount is reached, which still imposes a hard cap on high‑speed data.

Travelers can instead choose from fixed data plans such as the 10 GB plan valid for 30 days or the 1 GB plan valid for 7 days. These bundles give a set amount of high‑speed data that must be used within the specified validity period, offering a clear price–data relationship that can be more cost effective for most users.

FootySIMs does not provide a Japan eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for travelers in Japan. Users who need voice or text services can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Japan before purchasing a plan.

FootySIMs offers 3 single‑country data plans for Japan. One of those plans is a daily data cap plan, while the remaining two are fixed data amount plans. Prices for the plans range from $3.09 to $17.64, with data caps spanning 1 GB to 10 GB. Validity extends from 7 to 30 days, and some plans allow tethering, though speed may be reduced to 512 kbps.
