AlpineSIM for Japan FAQ

Does AlpineSIM offer unlimited data eSIM for Japan?

AlpineSIM does not provide a true unlimited data eSIM for Japan. All plans that carry the word “Unlimited” in their name actually have a fixed high‑speed data allowance, such as 500 MB/day, 1 GB/day, 2 GB/day, 5 GB/day or 10 GB/day, and the data capacity is capped at that amount; once the cap is reached the plan may stop or reduce speed, although the reduced speed is not listed in the available information.

If a traveler needs a larger data volume, AlpineSIM offers fixed‑data plans for Japan. For instance, a 50 GB plan for 30 days costs $23.54, a 20 GB plan for 30 days costs $11.36, and a 50 GB plan for 180 days costs $38.78. These fixed‑data options give a more generous data allowance without the limitations inherent in the “Unlimited”‑named plans.

Does AlpineSIM offer Japan eSIM with phone number and SMS?

AlpineSIM does not provide a Japan eSIM that includes a phone number or SMS capability. All of the AlpineSIM plans for Japan are data‑only, so travelers will not receive a local number for incoming or outgoing calls or texts. Instead, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection. However, some services may be restricted in certain destinations, so it is wise to check whether the apps you depend on are accessible in Japan before purchasing a plan.

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.
