SIMzip eSIM Data Plans for Japan

SIMzip does not offer any unlimited data eSIM plans for Japan. The provider sells fixed‑data options, including the Japan 40GB for 30 days plan, which gives 40GB of data for 30 days, and the Japan 20GB for 30 days plan, which supplies 20GB over the same period. Both plans work on 4G and 5G networks and allow tethering.

Choosing a fixed‑data plan can be more cost‑effective for most travelers. Only very heavy users who need more than the largest available fixed allowance might consider looking for an alternative unlimited option from another provider.

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.
