SIMzip eSIM Data Plans for Japan

SIMzip does not provide an unlimited data eSIM plan for Japan.
Travelers who need large data allowances can select from SIMzip’s fixed data plans, such as the 40GB plan valid for 30 days priced at $101.75 USD and the 20GB plan also valid for 30 days priced at $57.96 USD. These options offer substantial data and may be more cost‑effective for most users unless they require usage beyond the capped amount.

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.
