Lotso Travel eSIM Data Plans for Japan

Lotso Travel does not provide a truly unlimited high‑speed data eSIM for Japan. The plans that carry “Unlimited” in the name offer a set data allowance per day, such as 2GB/day, 3GB/day, or 5GB/day, and after that limit the speed to 1000kbps. If unlimited high‑speed data is needed, a fixed data plan can be a more practical and affordable choice. For example, Lotso Travel sells a Japan 20GB plan valid for 5, 10, 15, or 30 days and a Japan 10GB plan valid for 5 days, both of which provide a larger data pool without the daily cap and throttling. These fixed‑data options may be more cost‑effective unless a traveler requires very high bandwidth usage on a daily basis.

Lotso Travel does not provide a Japan eSIM that includes a local phone number or regular SMS capabilities. Their Japan plans are data‑only, so travelers can use mobile data for internet access only. For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram or iMessage, which operate over the data connection and do not require a traditional phone number or SMS service.

Lotso Travel offers 32 single‑country eSIM data plans for Japan only, as there are no multi‑country plans from this provider. Among these 32 plans, the provider offers two types of data structures: 20 “fixed data cap” plans that provide a set amount of data for the plan’s entire validity period, and 12 “daily data cap” plans that allow a limited amount of data each day, with any unused data not carried over. The plans span a wide price range from $5.00 to $79.00 and cover 1 GB to 20 GB of data, with validity periods between 5 and 30 days.
