ViaConecta eSIM Data Plans for Japan

ViaConecta does not offer a truly unlimited data eSIM plan for Japan. All plans that are marketed with an “Unlimited” name actually provide a fixed daily data allowance, in this case 1GB per day for the stated validity period, and the data is not unlimited. These are fixed data plans that expire after the set number of days.

Travelers who need more data can choose fixed data plans instead. For example, the “Japan 30 GB 30 Days” plan gives 30 GB of high‑speed data over 30 days, and the “Global 80 GB 365 Days” plan offers 80 GB for a full year. These larger data allowances can be more cost‑effective for most visitors unless they are extremely heavy data users.

No, ViaConecta does not offer a Japan eSIM plan that includes a phone number or SMS capability. They only sell data‑only eSIMs for Japan. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, although some destinations may restrict certain apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Japan before purchasing.

ViaConecta provides a total of 22 data plans that include Japan – 12 single‑country plans focused exclusively on Japan and 10 multi‑country plans that cover Japan along with other destinations. The available options span a price range from $4.53 to $173.94 and a data cap range of 1 GB to 80 GB. Some plans are defined by a fixed data amount, while others offer a daily data cap that resets each day.
