AlpineSIM for Japan FAQ

Does AlpineSIM offer unlimited data eSIM for Japan?

AlpineSIM does not provide an unlimited‑data eSIM for Japan. All of its Japan‑only products are fixed data plans with specified caps, such as the 10 GB/Day / 1 day bundle or the 50 GB / 30‑day plan. These fixed‑data offerings can be an economical choice for most travelers, while an extremely heavy data user might need to select the largest available plan.

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.
