Always Mobile for Japan FAQ

Does Always Mobile offer unlimited data eSIM for Japan?

Always Mobile does not provide an unlimited data eSIM for Japan. All of its Japan‑specific plans have a fixed data cap, the largest being 50GB.

Travelers can choose from fixed data plans such as the Japan 50GB 30Days plan, which costs $21.50 USD and is valid for 30 days, or the Japan 50GB 180Days plan, which costs $35.25 USD and is valid for 180 days. These plans offer 5G coverage on NTT docomo and KDDI/au networks and include tethering. Fixed data plans can be more cost‑effective unless a user requires an extremely high data volume.

Does Always Mobile offer Japan eSIM with phone number and SMS?

Always Mobile does not provide Japan eSIM plans that include a phone number or SMS service. The provider offers only data‑only eSIM plans for travelers going to Japan. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but the availability of these services in Japan may be limited or blocked in certain circumstances, so it is advisable to confirm that the apps you rely on are accessible before purchasing.

How many data plans does Always Mobile offer for Japan?

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.
