Does eSimfly offer unlimited data eSIM for Japan?
eSimfly does not offer a truly unlimited data eSIM for Japan.
The plans named “Japan Unlimited” contain 1 GB of high‑speed data per day; when that daily quota is reached the data is throttled, so the plan is not unlimited in the sense of an unrestricted data supply.
If a larger data allowance is desired, eSimfly provides fixed‑capacity options, such as 60 GB, 90 GB, or 100 GB plans valid for 180 days or 365 days, and 50 GB plans for 30 days or 180 days, among other alternatives.
Does eSimfly offer Japan eSIM with phone number and SMS?
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.
How many data plans does eSimfly offer for Japan?
eSimfly lists 24 single‑country packages that cover only Japan and 56 multi‑country solutions that include Japan. Prices range from roughly $1.37 up to $257.40, while data caps vary between 1 GB and 100 GB, encompassing both fixed‑data bundles and daily‑data‑cap options, with some plans allowing tethering.
