Frequently Asked Questions
Does eSIM Cards offer unlimited data eSIM for Japan?
eSIM Cards does not provide a genuinely unlimited high‑speed data plan for Japan. The plans that carry the name “Unlimited” actually offer 1 000 GB of data; once that amount is used, the speed may be reduced.
Travelers who require predictable high‑speed usage may choose one of the fixed data plans instead. For example, the Japan 300GB Travel Plan for 15 days provides a fixed amount of high‑speed data with no speed throttling, and can be more cost‑effective, especially for heavy data usage.
Does eSIM Cards offer Japan eSIM with phone number and SMS?
eSIM Cards provides only data‑only eSIM plans for Japan. No plan includes a local phone number or SMS capability. Travelers can still use the data connection to run VoIP applications such as WhatsApp, Telegram, or iMessage for voice and text communication.
How many data plans does eSIM Cards offer for Japan?
eSIM Cards currently offer 12 single‑country data plans and 2 multi‑country plans for travelers in Japan. The single‑country plans cover a price range of $4.15 to $69.12 USD and a data cap from 3 GB to 1, 000 GB, with validity periods between 4 and 30 days. The multi‑country plans are within the same price and data ranges but provide coverage in additional countries beyond Japan. Some packages feature a fixed data allotment while others use a daily data cap, allowing users to manage usage according to their stay duration. Tethering is permitted on certain plans, and speeds may be throttled once the data cap is reached.
