Strong eSIM eSIM Data Plans for Japan

Strong eSIM does not currently provide an unlimited data eSIM plan for Japan. Its offerings for that destination are fixed‑data packages, the most common being the Japan 50GB 30Days and Japan 20GB 30Days plans, each available for a set number of days and including tethering. Travelers who need higher data usage may choose a larger fixed plan or extend the validity, but an unlimited option is not part of Strong eSIM’s catalog for Japan.

Strong eSIM does not provide a Japan eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered, so the service cannot receive or send text messages or make calls using a local number. Travelers can instead use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection to make voice calls and send messages without a traditional phone number.

Strong eSIM provides 41 single‑country plans that cover Japan alone, and 50 multi‑country plans that include Japan among their destinations. The options span a price range from roughly $0.80 to $224.90, while data caps vary from 100 MB up to 50 GB and validity periods extend from 1 to 365 days. These plans may feature either a fixed data amount for a set period or a daily data cap for longer trips, with most of them allowing tethering.
