Travelsim Asia eSIM Data Plans for Japan

Travelsim Asia does not provide an unlimited data eSIM plan for Japan. All of the plans listed for this destination have a fixed data cap.

Customers who need larger data allowances can choose from the fixed‑data options that are available, such as the 50GB plan valid for 30 days priced at $34.99 USD or the 20GB plan valid for 30 days priced at $22.99 USD. These fixed plans can offer a more cost‑effective solution for most travelers unless they require very high or unlimited data usage.

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 provides 6 single‑country data plans that cover Japan and 7 multi‑country plans that include Japan. In total, there are 13 data plans available for travelers visiting Japan. The plans range in price from $3.99 to $120.99 USD and offer data caps between 1 GB and 50 GB, with validity periods spanning 7 to 180 days. Some plans allow tethering, providing additional flexibility for users who want to share data across multiple devices.
