esimzon eSIM Data Plans for Japan

Yes, esimzon sells unlimited data eSIM plans for Japan. The unlimited options range from 4 days to 15 days of validity and are priced between $9.90 USD and $30.00 USD. These plans are advertised as high‑speed 4G/5G connections, although the package notes that speed may be throttled after certain usage thresholds.

Because the unlimited plans may be subject to a Fair Usage Policy, speeds can be reduced if heavy usage occurs. If you are concerned about potential speed restrictions, contact esimzon directly to confirm whether a FUP applies and to find out how many data hours are typically available at normal speed.

esimzon does not provide a Japan eSIM that includes a phone number or SMS capability. The available plans are data‑only and do not support inbound or outbound calls or traditional SMS messages. Travelers can still use communication apps such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging without requiring a local phone number.

esimzon currently offers six data plans for Japan, including five single-coverage plans specifically for Japan and one multi-country plan that includes Japan alongside other destinations. These plans range in price from approximately $4.00 to $28.00 and offer data allowances between 3GB and 20GB. Plans generally have a validity period of 30 days. The available options include both fixed data amounts and varying data caps to suit different travel needs.
