Hungry eSIM eSIM Data Plans for Japan

Hungry eSIM does not provide a truly unlimited data eSIM for Japan. Every plan that carries “Unlimited” in the name actually has a fixed data allowance, ranging from 500MB to 10GB. Once that limit is reached, the speed drops to a throttled level such as 384kbps, 512kbps or 1 Mbps.

Travelers who need large amounts of data can instead opt for the fixed‑data plans that Hungry eSIM offers, such as the 50GB 30‑day plan, the 20GB 30‑day plan, or the 50GB 180‑day plan. These plans give full‑speed high‑speed data for the entire validity period without the speed reduction that applies to the so‑called “Unlimited” plans.

Hungry eSIM does not provide a Japan eSIM that includes a local phone number or SMS capability. Only data‑only plans are available for Japan. Travelers who need voice or text can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but not all destinations allow unrestricted access to these services. It is recommended that travelers confirm whether the apps they depend on are accessible in Japan before making a purchase.

Hungry eSIM provides a wide selection of options for travelers visiting Japan. In Japan exactly 36 single–country data plans are available, while 58 multi‑country plans cover Japan alongside other destinations. These plans span a price range from about $1.84 to $179.36 USD and offer data caps from 100 MB up to 50 GB, giving users flexibility to choose between low‑cost, short‑term options and larger, longer‑term packages that may be bundled with coverage for other countries.
