EZsim eSIM Data Plans for Japan

EZsim does not provide an unlimited data eSIM plan for Japan. The available offerings are fixed‑data plans, such as the Japan – 20GB/30Days plan that costs $22.20 USD, the Japan – 10GB/30Days plan priced at $11.55 USD, and the Japan – 5GB/30Days plan for $6.20 USD. For travelers who do not need very heavy data usage, choosing one of these fixed plans can be a more cost‑effective option compared to a higher‑priced unlimited plan, which is not available from EZsim in Japan.

EZsim does not provide a Japan eSIM plan that includes a phone number or SMS service. Only data‑only eSIM plans are offered by EZsim for Japan, and travelers can use data‑dependent VoIP apps such as WhatsApp, Telegram, or iMessage to make calls and send messages.

EZsim offers 23 single‑country data plans for Japan. None of those plans provide multi‑country coverage, so no multi‑country options are available. The plans vary in price from about $1.85 to $22.20 and provide data caps ranging from 1 GB up to 20 GB for validity periods between 1 and 30 days. Some plans are structured as daily data caps—allowing a set amount of data each day—while others offer a fixed data amount for the entire validity period. All plans share common features such as tethering, while the daily‑cap variants usually incur a slightly higher cost compared to the fixed‑cap options.
