Yatelo does not provide a true unlimited data eSIM for Japan; every plan branded “Unlimited” actually contains a 2GB cap, after which the speed is throttled to 1000kbps. This is the only unlimited‑named offering and it is not unlimited in the sense of continuous high‑speed data.
Instead, Yatelo offers a range of fixed data plans for Japan that can be used as alternatives. Examples include a 10GB plan for 30 days priced at $6.91, a 20GB plan for 30 days at $11.73, and a 50GB plan for 30 days at $22.15. These fixed plans may be more cost effective unless the user is an extremely heavy data consumer.
