Roamable for Japan FAQ

Does Roamable offer unlimited data eSIM for Japan?

Roamable does not offer any unlimited data eSIM plan for Japan. Travelers can instead choose from several fixed data plans that provide large data allowances, such as the Japan 50GB 30 Days plan priced at $54.80 USD or the Japan 50GB 180 Days plan priced at $87.80 USD. Because these plans have fixed data limits, they can be more cost‑effective for many users, especially those who do not require a high‑volume data allowance that exceeds the fixed plan limits.

Does Roamable offer Japan eSIM with phone number and SMS?

Roamable does not provide a Japan eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for Japan. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are accessible in Japan before purchasing, as some destinations may block or restrict certain apps.

How many data plans does Roamable offer for Japan?

Roamable provides nine single‑country eSIM plans that are dedicated to travel within Japan, allowing users to receive data exclusively while visiting that country. In addition, there are 40 multi‑country plans that include Japan as one of the destinations covered, giving access to data across several countries simultaneously. The plans range in price from about $0.60 to $272.84, with data allowances spanning from 500 MB up to 50 GB and validity periods between 7 and 365 days. Some of the plans also permit tethering, enabling users to share the data connection with other devices.
