Frequently Asked Questions

Does eSIM.sm offer unlimited data eSIM for Japan?

The current catalog lists only fixed data options, such as a 20GB 30‑day plan priced at $40.00 USD and a 10GB 30‑day plan priced at $21.20 USD. These large data allowances can be more cost‑effective for travelers who do not need unrestricted data usage. For users whose data needs exceed a fixed allowance, eSIM.sm offers no unlimited alternatives for Japan.
