eSIM4Travel eSIM Data Plans for Japan

eSIM4Travel does not provide a truly unlimited high‑speed data plan for Japan. The plans branded “Unlimited‑xDays‑Japan” give a daily allowance of 3GB, after which the speed is reduced to 1024kbps.

For travelers who need a larger data allowance, eSIM4Travel offers fixed‑data options such as the 50GB/30Days 5G plan priced at $50.35 USD, or the 50GB/365Days plan for $200 USD that covers Japan and 69 other countries. These fixed‑data plans are typically more cost effective for heavy data users.

eSIM4Travel does not provide any Japan eSIM that includes a mobile phone number or SMS support. The only plans available from this provider for Japan are data‑only plans that grant internet access without voice or text capabilities. Travelers who wish to make calls or send messages can rely on internet‑based VoIP services such as WhatsApp, Telegram, or iMessage, which work over the data connection without requiring a phone number or SMS.

eSIM4Travel offers 15 single‑country data plans for Japan and 16 multi‑country plans that include Japan. The plans are available in both fixed data amount and daily data cap formats; fixed plans give a set amount of data for the validity period, while daily cap plans limit the amount of data that can be used each day. Prices for the Japanese‑focused plans range from about $1.31 to $200, and data caps span from 1 GB up to 90 GB.
