Alodata does not provide a truly unlimited data eSIM for Japan. The plans that carry “Unlimited” in their name actually give a fixed daily allowance of 1 GB and throttle speeds to 1280 kbps after the limit is hit, so they are limited plans rather than free‑flow unlimited options. Travelers who need higher data volumes can choose from alodata’s fixed‑data plans, such as the 20 GB plan valid for 30 days at about $29 or the 50 GB plan valid for 90 days for roughly $221, which deliver full 4G/5G speeds while the data cap remains unexceeded and can be more cost‑effective unless the user requires extremely heavy data usage beyond the daily 1 GB allocation.
Alodata does not provide eSIM plans for Japan that include a phone number or SMS capability. The provider only offers data‑SIMs in that region. Travelers can still use popular VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice and text communication.
Alodata provides 12 single‑country data plans that cover Japan exclusively and 17 multi‑country plans that include Japan among other destinations. Across its catalogue the price ranges from roughly $4 to $320, while the data caps vary between 1 GB and 50 GB. Plans are categorized mainly as daily data cap offerings—about nine such plans that reset every day—or fixed data cap packages, twenty of which offer a set amount of data for the full validity period. Some selections allow tethering and apply a reduced speed of 1280 kbps.
