ASIMGO eSIM Data Plans for Japan

Yes, ASIMGO offers unlimited data eSIM plans for Japan. The plans range in price from $2.05 for a 1‑day plan to $68.31 for a 30‑day plan, and the validity period varies from 1 day to 30 days. Most unlimited plans use 5G networks and list a maximum speed of 5000kbps or 10000kbps, with a note that speeds may be throttled after heavy usage.

If you are concerned about potential speed restrictions, you can contact ASIMGO to confirm whether a Fair Usage Policy applies and to find out the typical amount of data that can be used at normal speed.

ASIMGO does not provide a Japan eSIM with a phone number or SMS capability. The provider only offers data‑only eSIM plans for Japan. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict certain apps, so it is advisable to verify that the services you need are accessible in Japan before purchasing.

ASIMGO provides 133 single‑country data plans and 394 multi‑country plans that include Japan. The plans vary in price—from roughly $0.54 to $126.50—while the data limits range from 500 MB up to unlimited. Customers can choose between fixed‑data packages that offer a set amount of data for the validity period and daily‑cap packages that restrict the data that can be used each day.
