Always Mobile eSIM Data Plans for Japan

Always Mobile does not provide an unlimited data eSIM plan for Japan. All available plans have a fixed data allowance.

The provider offers fixed data options such as Japan 50GB 30Days for $21.50 USD and Japan 50GB 180Days for $35.25 USD. These high‑cap plans can be a more economical choice for travelers with heavy data usage compared with purchasing a lower‑cap plan.

Always Mobile does not offer an eSIM in Japan that includes a local phone number or SMS functionality. Travelers can only purchase a data‑only plan for that country. To make phone calls or send messages, you would need to use VoIP or messaging applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

Always Mobile offers 8 single‑country plans and 31 multi‑country plans for use in Japan. These plans cover a price range from about $2.50 to $111.75 and data amounts between 1 GB and 50 GB, with validity periods that can span 7 to 365 days. Plans are typically sold as fixed data packages—where each SIM provides a set amount of data for the chosen period—though some may offer daily data caps that reset each day, giving travelers flexibility based on their daily usage needs.
