Travelsim Asia eSIM Data Plans for Japan

Travelsim Asia does not provide an unlimited data eSIM plan for Japan. The plans listed for Japan have data caps of 50GB, 20GB, or 10GB, each valid for 30 days. Travelers who need more data can choose a fixed‑data option such as the 50GB plan priced at $34.99 USD or the 20GB plan at $22.99 USD, which may offer a more cost‑effective solution unless the user is an extremely heavy data consumer.

Travelsim Asia does not offer an eSIM for Japan that includes a local phone number or SMS capability. The provider only sells data‑only plans for this destination, so travelers who need inbound or outbound voice and text services will need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. It is advisable to confirm that these apps are accessible in Japan before purchasing a plan.

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.
