Giga.Tel eSIM Data Plans for Japan

Yes. Giga.Tel lists a number of unlimited‑data eSIM plans for Japan. The plans are available for 3 to 15 days and are priced from $5.49 to $28.49 USD. They allow tethering and include a Fair Usage Policy, so while the data allowance is unlimited, speeds may be throttled after heavy usage. The maximum advertised speeds are up to 10 Mbps, but some plans list a lower maximum speed. If you need confirmation on the FUP details or typical speed limits, contact Giga.Tel directly.

Giga.Tel does not provide eSIM plans that include a phone number or SMS service for travels to Japan. The provider’s Japan offerings are limited to data‑only eSIM packages, so travelers will not receive an inbound or outbound phone number. For voice and messaging, users can rely on internet‑based applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to particular VoIP services, so it is advisable to verify that the apps needed for communication work in Japan before purchasing a Giga.Tel data plan.

Giga.Tel provides 272 single country plans and 239 multi country plans for Japan. The plans cover a price range from $2.15 to $258.95 and data caps from 1 GB up to unlimited. Validity periods vary from 1 to 365 days. Giga.Tel offers both fixed data cap plans, which provide a set amount of data for the entire validity period, and daily data cap plans, which reset the data allowance each day. The provider offers a mix of daily and fixed data cap options across its single country and multi country offerings.
