Frequently Asked Questions
Does eSIM Cards offer unlimited data eSIM for Japan?
eSIM Cards does not provide a truly unlimited data eSIM for Japan. The plans labeled “Japan Unlimited eSIM” contain a large data allowance of 1 000GB. After that amount, the network speeds are throttled, so the plan is not unlimited in the sense of ongoing high‑speed data without limits.
Travelers looking for a truly unlimited experience would need to choose a different provider or a larger fixed‑data plan. eSIM Cards offers fixed data options such as a 300GB plan for 15 days, which while capped, may be more economical for heavy data users who can stay within the defined limit.
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 offers 12 single‑country plans that cover Japan, and 2 multi‑country plans that include Japan. The plans range in price from $4.09 to $69.48 USD and provide data caps between 3 GB and 1, 000 GB, depending on the specific option chosen. Some plans include a fixed data amount for the validity period, while others set a daily data cap for more flexible usage.
