eSimfly eSIM Data Plans for Japan

eSimfly does not provide truly unlimited data eSIM plans for Japan. All plans listed under the “Japan Unlimited” name give 1 GB of high‑speed data per day and are subject to a daily limit; after the cap is reached the speed is reduced, though the dataset does not specify the throttled speed.

For travelers who need larger data allowances, eSimfly offers fixed‑data plans such as the Japan 50GB 30Days plan priced at $28.90 USD or the Japan 50GB 180Days plan at $47.60 USD. These fixed‑data options may be more cost‑effective unless the user requires an extremely high data volume.

eSimfly does not provide a Japan eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only eSIMs for Japan, so travelers cannot receive inbound SMS or make outbound voice calls through a local phone number. For messaging and voice communication, users can rely on internet‑based apps such as WhatsApp, Telegram, or iMessage, which operate over the data connection.

eSimfly provides 16 single‑country plans that cover Japan and 62 multi‑country packages that include Japan. The catalog features 72 fixed‑data‑cap options and 6 daily data‑cap options, with data limits ranging from 1 GB to 100 GB. Prices vary from about $1.19 to $224.40, and validity periods span from 3 to 365 days. Many plans also allow tethering.
