Data plans for this provider are automatically updated. While we strive to keep the information accurate, we cannot guarantee its completeness or accuracy. Please confirm all details on the provider's official website or app before purchasing.
Bloomy eSIM does not provide a plan that offers truly unlimited high‑speed data in Japan. All plans marketed with “Unlimited” in their name actually contain a fixed data cap, such as 1GB, 2GB, up to 10GB per day, after which no further data is available and the speed is not sustained.
Travelers who need a larger, flat data allowance can choose one of Bloomy eSIM’s fixed‑data plans. For example, a 50GB plan for 30 days costs $30.15 USD, and a 20GB plan for the same validity costs $14.54 USD. These fixed‑data options are often more cost‑effective for heavy data usage than the limited‑day, per‑day “Unlimited” plans.
Bloomy eSIM does not provide a phone number or SMS service for Japan. All available plans are data‑only, so travelers will have access only to high‑speed internet without built‑in verbal or text messaging capabilities.
If a phone number is needed, travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations might restrict access to certain VoIP services, so it is advisable to check that the apps required for communication are available in Japan before purchasing a Bloomy eSIM.
Bloomy eSIM offers 178 single‑country plans and 209 multi‑country plans in Japan. The available plans range in price from $0.00 to $2, 551.50 and cover data caps from 100 MB to 50 GB. Bloomy provides both fixed‑amount data plans (73) and daily data‑cap plans (314), so customers can choose between a predetermined data bundle or a plan that renews daily at a set maximum.
