AlpineSIM for Japan FAQ

Does AlpineSIM offer unlimited data eSIM for Japan?

AlpineSIM does not provide a truly unlimited data eSIM for Japan; all plans labeled “Unlimited” actually have a fixed daily data cap, such as 500 MB/day or 1 GB/day. After the allocated amount is used, data continues at a reduced speed.

Travelers who need more data can choose from AlpineSIM’s fixed‑data plans. For example, the 20 GB plan runs for 30 days at $11.29 USD, and the 50 GB plan runs for 30 days at $23.40 USD. These plans offer a larger, unthrottled data allowance than the daily‑cap options and are suitable for users who are heavy data consumers.

Does AlpineSIM offer Japan eSIM with phone number and SMS?

AlpineSIM does not provide a Japan eSIM that includes a local phone number or SMS capability. Travelers using AlpineSIM plans for Japan will only receive high‑speed Internet data; voice and text messaging must be handled through data‑based services such as WhatsApp, Telegram or iMessage. This approach allows connectivity without a traditional Japanese phone number, while still enabling communication via popular VoIP applications.

How many data plans does AlpineSIM offer for Japan?

AlpineSIM offers 58 single‑country plans that are specifically for Japan and 156 multi‑country plans that include Japan in their coverage. Prices for these plans span from $0.41 to $273.24, while data caps range from 100 MB up to 50 GB. The catalogue includes both fixed‑data‑cap options—which provide a set amount of data for the entire validity period—and daily‑data‑cap options—which reset a separate cap on a daily basis.
