ChillaxSIM does not provide a truly unlimited data eSIM for Japan. The plans that carry “unlimited” in their name offer 1 GB per day; once the daily limit is reached, the speed is throttled to 5000 kbps.
If a fixed data allowance is preferable, ChillaxSIM offers larger flat‑data options. For example, a 50 GB plan valid for 60 days costs $28.90 USD, and a 30 GB plan for 60 days costs $20.90 USD. These plans use 5G and, after the data cap is reached, the speed is reduced to 128 kbps. Choosing a fixed data plan can be more cost‑effective, especially for travelers who do not need a large amount of high‑speed data overnight.
ChillaxSIM does not provide a Japan eSIM that includes a phone number or SMS capability. Travelers can purchase only data‑only plans from this provider for use in Japan.
If call or message functionality is needed, users can rely on VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, these services may be blocked or restricted in certain destinations, so it is wise to verify that the apps you depend on work in Japan before buying a plan.
ChillaxSIM offers 28 single‑country data plans that cover Japan, along with 5 multi‑country plans that include Japan in their coverage area. The provider’s plans are split into daily data cap options (19 of these) and fixed data cap options (14 of these). Across all plans the price range is approximately USD 3.10 to 79.30, while the data caps vary from as little as 1 GB up to 50 GB, depending on the plan’s duration and coverage type.
