Yes, ByteSIM sells unlimited‑data eSIM plans for Japan. The available options are the “Japan – 5G Ultra Unlimited eSIM by KDDI” series, which come in several validity periods ranging from 4 days to 31 days. Prices start at $18.90 USD for the 4‑day plan and go up to $79.90 USD for the 31‑day plan.
These plans are advertised as unlimited, but the provider applies a Fair Usage Policy: speeds may be throttled after heavy usage, usually limiting the data rate to about 10 240 kbps. Users concerned about potential speed restrictions should contact ByteSIM directly to confirm whether a throttle applies and to determine how much data remains available at normal speed.
ByteSIM does not offer Japan eSIMs that include a phone number or SMS capability. Their Japan plans are strictly data‑only; calls and texts would need to be handled through internet‑based messaging or VoIP services such as WhatsApp, Telegram, or iMessage.
