Frequently Asked Questions
Does ZenSim offer unlimited data eSIM for Japan?
ZenSim does not offer a true unlimited data eSIM plan for Japan. The plans that carry the “Unlimited” name provide a daily allowance of 3 GB; after that limit is reached the speed is reduced.
Travelers looking for a higher data volume can choose from ZenSim’s fixed‑data plans. For example, Japan 20 GB for 10 days costs $23.00 USD, and Japan 20 GB for 30 days costs $24.00 USD. These options give users a larger, predictable data budget and can be more cost‑effective for most travelers.
Does ZenSim offer Japan eSIM with phone number and SMS?
ZenSim does not provide any eSIM plans for Japan that include a phone number or SMS capability. Only data‑only eSIMs are offered. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection instead.
How many data plans does ZenSim offer for Japan?
ZenSim offers eight single‑country plans for Japan and eight multi‑country plans. The available plans span a price range of roughly USD 10 to USD 70 and provide data caps between 3 GB and 20 GB. Some options are based on a fixed data amount, while others use a daily data cap, with both types present across the single‑ and multi‑country offerings.
