Bordersim eSIM Data Plans for Japan

Bordersim does not currently offer any unlimited‑data eSIM plan for Japan. All of its Japan‑specific plans are fixed‑data allowances.

For travelers who need large amounts of data, Bordersim provides fixed‑data eSIM options that could be more cost‑effective than buying multiple smaller packages. The Japan 50GB 30Days plan, priced at $22.99 USD, delivers 5G connectivity for a validity of 30 days and includes tethering. A longer‑term option is the Japan 50GB 180Days plan, priced at $36.49 USD and delivering the same 5G speed for 180 days. These plans provide substantial data for users who consume moderate to heavy data without the need for an unlimited tier.

Bordersim does not offer Japan eSIM plans that include a phone number or SMS capabilities. Only data‑only eSIM options are available for Japan. Travelers who need voice or messaging can still use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may block or restrict access to certain apps, so it is advisable to confirm that these services work in Japan before purchasing.

Bordersim offers 23 single‑country plans and 28 multi‑country plans for Japan. The provider provides both fixed data amounts and daily data cap options, so travelers can choose a plan that delivers a set amount of data over its validity period or one that resets every day. Prices range from roughly $2.99 to $111.99, while data caps span from 100 MB to 50 GB, giving a wide range of options to suit different needs.
