Lotso Travel eSIM Data Plans for Japan

Lotso Travel does not provide a truly unlimited data eSIM for Japan. The plans listed under “Unlimited” use a daily limit of 2GB to 5GB; once the daily allowance is reached, the speed throttles to 1000kbps. For travelers who need high‑speed data without a daily cap, Lotso Travel offers fixed‑data plans such as the Japan 20GB plan (valid for 5, 10, 15 or 30 days) and the Japan Unlimited MAX plan (5GB/day for 5 to 30 days). These fixed‑data options may be more cost‑effective for heavy‑data users compared to the capped “Unlimited” plans.

Lotso Travel does not offer Japan eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available for use in Japan, and travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage for calling and messaging over the data connection.

Lotso Travel lists 32 single‑country data plans for Japan and 32 multi‑country plans that include Japan. The price range for these plans is roughly $5.00 to $79.00, while the data caps vary from 1 GB to 20 GB. Some offerings provide a fixed data amount for the entire validity period, whereas other options implement a daily data cap, giving users flexibility on how much data they can use each day.
