Roamic does not provide a plan that offers truly unlimited high‑speed data in Japan. The plans titled “Japan eSIM Unlimited Data” give 3GB of high‑speed data per day on the 1‑day to 30‑day options; after the 3GB limit is reached, the speed is reduced.
For travelers who require more data, Roamic offers fixed‑volume plans. Examples include a 20GB/30‑day plan priced at $17.40 USD, a 10GB/30‑day plan at $9.28 USD, and a 50GB/180‑day plan for $40.62 USD. These fixed plans may be more cost‑effective for heavy data users.
Roamic does not provide any eSIM plan for Japan that includes a phone number or SMS capability. Its Japan offerings are data‑only. Travelers can still use apps such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.
Roamic offers 14 single‑country data plans that can be purchased for Japan, as well as 13 multi‑country plans that include Japan among their covered destinations. The plans span a price range from approximately $2.31 to $174.12 and a data cap range from 1 GB to 50 GB. In addition to fixed‑data‑cap options, Roamic provides daily‑data‑cap plans whose data allowance replenishes each day.
