Does eSimfly offer unlimited data eSIM for Japan?
eSimfly does not provide a plan with an uncapped high‑speed data allowance for Japan. The plans that carry the “Unlimited” label offer a total of 1 GB per day for the validity period; after the allotted 1 GB the data is no longer counted toward that limit and the speed is reduced. For travelers who need more data, eSimfly offers fixed‑data options such as Japan 50GB 30Days (IIJ) for $19.89 USD or Asia 100GB 180Days for $257.40 USD, which may be more cost effective for heavy data users.
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 offers 16 single‑country plans for Japan and 72 multi‑coverage plans that include Japan as part of their network. Among these, 13 plans use a daily data cap while the remaining 75 provide a fixed data amount for the entire validity period. Prices start around $1.48 and can go up to roughly $257.40, with data caps ranging from 1 GB to approximately 100 GB, giving travelers a wide range of options depending on their usage needs.
