Kolet eSIM Data Plans for Japan

Kolet does not provide any unlimited‑data eSIM plans for Japan. Travelers can choose from fixed‑data options, such as a 20GB plan valid for 30 days priced at $32.99 USD, a 20GB plan valid for 365 days priced at $82.49 USD, or a 10GB plan valid for 30 days priced at $21.99 USD. These plans offer 4G, 5G, LTE connectivity across Japan, and selecting a fixed data plan can be more cost‑effective for users who do not require truly unlimited data.

Kolet does not provide eSIM plans that include a phone number or SMS capability for travelers in Japan. All Kolet eSIMs sold for Japan are data‑only plans; they do not support inbound or outbound voice calls or text messaging through theSIM. Travelers who need to communicate while on the move can instead use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection provided by the eSIM.

Kolet provides five single‑country data plans that cover Japan, as well as ten multi‑country plans that include Japan among other destinations. The plans range in price from $3.99 to $82.49 and offer between 1 GB and 20 GB of data, with validity periods that can be as short as 30 days or extend up to 365 days.
