Yoho Mobile offers a range of unlimited data eSIM plans for Japan. These plans provide unlimited high‑speed data with validity periods that range from 1 day to 30 days, and prices that span from $1.00 USD up to $79.20 USD. The maximum speed available on these plans is 5000 kbps, though the network may throttle speeds after heavy usage in accordance with a Fair Usage Policy.
If you are concerned about potential speed restrictions, you should contact Yoho Mobile directly to confirm whether the Fair Usage Policy applies to the specific plan you choose and to find out how much data remains available at normal speed once a usage threshold is reached.
