Travelsim Asia does not provide an unlimited data eSIM plan for Japan. The current offerings in Japan are fixed‑data plans, such as 10GB for 30 days, 20GB for 30 days, or 50GB for 180 days. All of these plans include tethering and use the 5G network. Since no unlimited option is available, travelers who require large amounts of data may find a fixed‑data plan to be a more cost‑effective choice unless they are an extremely heavy data user.
Travelsim Asia does not provide a Japan eSIM that includes a phone number or SMS capability. The available plans are data‑only, so you will not receive a local number for voice calls or text messaging. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without needing a traditional phone number.
Travelsim Asia offers six single‑country data plans for Japan. Prices span from $3.99 to $120.99 while data caps range from 1 GB to 50 GB; all plans permit tethering. No multi‑country plans are available for Japan on the provider’s catalogue.
