Giga.Tel eSIM Data Plans for Japan

Giga.Tel does not provide a truly unlimited high‑speed data eSIM plan for Japan. Its “Global Unlimited” products name the plan as unlimited but the data cap is 1 GB per day, after which the speed is throttled to 512 kbps. Travelers who need more data without a daily cap can choose from Giga.Tel’s fixed plans, such as the 90 GB plan valid for 365 days or the 60 GB plan valid for 90 days, as well as several 50 GB 30‑day options. Selecting a fixed‑data plan can be more cost effective for users who require a larger amount of data and do not want speed reductions after a daily limit.

Giga.Tel does not provide eSIM plans for Japan that include a phone number or SMS capabilities. The available plans are strictly data‑only, meaning users can access the internet but cannot receive inbound calls or SMS messages on a local Japanese number. Travelers can still use data‑based VoIP applications such as WhatsApp, Telegram, and iMessage for voice calls and messaging without relying on a local phone number or SMS service, but no native telephony or SMS feature is offered by Giga.Tel for Japan.

Giga.Tel lists 24 single‑country data plans that cover Japan and an equal number of 24 multi‑country plans that include Japan. Across both categories the available plans span a price range of roughly $4.49 to $307.99 and offer data caps from 500 MB up to 90 GB, with validity periods that can last from a single day to a full year. Some plans use a fixed data amount, while others provide a daily data cap that resets each day, allowing customers to choose between a static bundle and a daily‑reset option depending on their usage patterns.
