AeroSims eSIM Data Plans for Japan

AeroSims does not provide a plan that offers truly unlimited high‑speed data for Japan. The plans that carry “Unlimited” in their name grant 5 GB of high‑speed data per day; once that amount is used the speed is reduced to 384 kbps, so the data is capped. Travelers who need a larger and constant data supply can choose from AeroSims’ fixed‑data plans, such as the Tokyo 50 GB/30 days plan or the Tokyo 20 GB/30 days plan, both of which give a single, larger data allowance that can be topped up while the eSIM remains valid.

AeroSims does not offer any Japan eSIM that includes a phone number or SMS capability. The provider only sells data‑only eSIM plans for Japan. Travelers who need voice or text functionality can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that the apps they rely on are accessible in Japan before purchasing an eSIM.

The information provided lists a total of 13 single‑country plans and 27 multi‑country plans overall for AeroSims, but it does not give a country‑by‑country breakdown. Consequently, the exact number of AeroSims data plans available for Japan is not specified in the current data.
