MicroEsim eSIM Data Plans for Japan

MicroEsim offers unlimited data eSIM plans for Japan that are available for purchase in a range of validity periods. Prices start at $2.13 USD for a 1‑day plan and go up to $43.92 USD for a 15‑day plan. The plans are valid from 1 day up to 15 days. While the plans are marketed as unlimited, the data bandwidth may be reduced after heavy use under a fair‑usage policy, and the normal speed can be capped when speeds are curtailed. Travelers who are concerned about potential throttling should contact MicroEsim to confirm whether a fair‑usage limit applies and the typical sustained speed at full allowance.

MicroEsim does not provide a Japan eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are available from this provider for Japan. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without a local phone number.

MicroEsim offers 136 single‑country plans that cover Japan, along with 97 multi‑country plans that include Japan. The single‑country offerings range in price from $0.81 to $165.24 and provide data caps from 500 MB up to unlimited, with validity periods of one to 60 days. The multi‑country plans follow the same price and data ranges but are available in both fixed‑data and daily‑cap formats, allowing a traveler to choose a plan that best fits a day‑by‑day usage pattern. Several plans also permit tethering and include speed‑tier options such as reduced speed at 128, 200, 256, 384, or 5000 kB/s and a throttled speed option.
