Giga.Tel eSIM Data Plans for Japan

Giga.Tel does not provide a truly unlimited high‑speed eSIM plan for Japan. All of its Japan‑covered options either have a fixed data cap per day or a total data allowance that, after being consumed, throttles the connection to a reduced speed such as 512 kbps. For travelers who want a large, uninterrupted data allotment, Giga.Tel offers fixed plans like the 60 GB 90‑day plan priced at $59.99 USD, the 90 GB 365‑day plan at $181.99 USD, or the 50 GB 30‑day plan at $25.49–$30.49 USD. Choosing one of these fixed‑data plans can be more cost‑effective for moderate to heavy data users compared to the “unlimited” name plans that ultimately enforce speed reductions after the daily limit is reached.

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 provides 24 single‑country plans and 24 multi‑country plans for Japan.
The available plans vary in price from about $4.99 to $307.99 and in data capacity from 500 MB up to 90 GB. Some of the selections are based on a fixed data amount (35 options across all plans) while others are daily data‑cap based (13 options), offering travelers flexibility depending on their usage patterns.
