AlpineSIM for Japan FAQ

Does AlpineSIM offer unlimited data eSIM for Japan?

AlpineSIM does not provide a truly unlimited data eSIM for Japan. Plans that carry “Unlimited” in their name actually supply a fixed amount of high‑speed data—such as 500 MB per day, 5 GB per day, or 10 GB per day—after which the data capacity stops increasing and the speed may be reduced. Therefore, there is no continuous, unlimited data allowance with AlpineSIM in Japan.

Travelers who need larger data volumes can choose from AlpineSIM’s fixed‑data plans. For example, a 50 GB plan for 30 days costs $23.80, while a 20 GB plan for the same validity period is priced at $11.49. These plans guarantee the full, high‑speed data cap for the entire validity period, offering a more predictable and often cost‑effective alternative to the limited “Unlimited” packages.

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.
