EscapeSIM eSIM Data Plans for Japan

Yes, EscapeSIM offers a range of unlimited data eSIM plans for Japan. The plans are valid from 3 days to 31 days and cost between $5.39 USD for a 3‑day plan and $75.30 USD for a 31‑day plan, all using 5G networks with a maximum advertised speed of 10 Mbps (10 Mbps). All of these plans list “Unlimited” for the data cap and include tethering capabilities, but they note that speeds may be throttled after heavy usage under EscapeSIM’s Fair Usage Policy.

If you plan on using a lot of data or want confirmation of the typical data volume that can be streamed at normal speed, it’s advisable to contact EscapeSIM directly. They can provide a full explanation of how the Fair Usage Policy applies and give you details about the portion of the plan that remains at standard speed for each validity period.

EscapeSIM does not provide Japan eSIMs that include a local phone number or SMS capability. The provider’s Japan plans are data‑only, so travelers cannot make traditional voice calls or receive SMS messages on a local number. However, VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection for communication without the need for a phone number or SMS.

EscapeSIM’s catalogue includes 56 single‑country plans and 33 multi‑country plans overall, but the dataset does not specify how many of those are dedicated to Japan.
