eSimfly eSIM Data Plans for Japan

eSimfly does not provide a truly unlimited high‑speed data eSIM for Japan. All of the plans branded Japan Unlimited give 1GB of high‑speed data per day and reduce speed to 5000kbps once that daily limit is reached. For travelers who need more data, eSimfly offers fixed‑data alternatives such as the Japan 50GB 30Days (IIJ) plan priced at $28.05 for 30 days and the Orange World 100 GB 30Days plan priced at $69.07 for 30 days. These larger data plans can be a more cost‑effective choice unless a user requires the higher daily capacity.

eSimfly offers a Japan eSIM plan that includes a phone number and SMS capabilities. The plan is called Orange World 20 GB 30 days, priced at $33.96 USD and valid for 30 days. It provides a phone number with dialing code +33 (a French number), and the plan supports both inbound and outbound voice calls as well as inbound and outbound SMS. Users who need to make or receive calls and send or receive text messages can confirm the exact functionality with eSimfly before purchasing.

eSimfly lists 16 single‑country plans and 37 multi‑country plans that include Japan. The available plans range in price from about $2.16 to $121.38, with data caps between 1 GB and 100 GB. Among these, 12 options feature a daily data cap while 41 offer a fixed data amount.
