SIMzip eSIM Data Plans for Japan

SIMzip does not provide an unlimited data eSIM plan for Japan.
The provider offers fixed‑data plans that range from 3GB for 5 days up to 40GB for 30 days. For example, the Japan 40GB for 30 days plan costs $216.00 USD and the Japan 20GB for 30 days plan costs $118.80 USD. Fixed‑data packages may be more cost‑effective for travelers who need large amounts of data but do not exceed the specified caps, while heavy data users might find a dedicated unlimited plan from other operators more suitable.

SIMzip does not offer a Japan eSIM that includes a local phone number or SMS capability. The provider’s Japan plans are data‑only; they provide internet access but do not support calling or text messaging over a traditional phone network. For voice or text communication, travelers generally rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection.

SIMzip currently offers 7 single-country data plans specifically for Japan. These plans range in price from $14.40 to $216.00 and provide data allowances between 1GB and 40GB. Plan validity periods vary from 5 to 30 days. SIMzip does not currently offer multi-country plans that include Japan as part of their coverage. Tethering is permitted with some of the available plans.
