A: We cannot guarantee successful activation.

A “physical eSIM” is a product that uses a physical SIM card with special technology to provide eSIM-like functionality. It is different from the standard eSIM built into smartphones.

JB Voice eSIM activation requires an EID (32 digits). Depending on the EID’s source, authentication status, or carrier system restrictions, a physical eSIM may encounter an “EID Error” during activation.

Therefore, customers using a physical eSIM may submit an application, but we cannot guarantee successful activation.

⚠️ If activation fails due to an EID-related issue, a reissue fee of ¥2,200 (tax included) will apply.
