MicroEsim eSIM Data Plans for Japan

MicroEsim does provide unlimited data eSIM plans for Japan. The plans range in validity from 1 day to 19 days and are priced from about $2.24 USD for the 1‑day package up to $61.73 USD for the 19‑day option. Most of these unlimited plans allow tethering, and the advertised speed can be reduced to 5Mbps or 10Mbps, with the possibility that higher speeds may be throttled under a fair‑usage policy.

Because the exact amount of data that can be used at normal speed may vary with a provider‑specific fair‑usage policy, travelers who need precise details about how many gigabytes can be consumed before throttling should contact MicroEsim directly for confirmation.

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 provides 127 single‑country data plans and 97 multi‑country plans that include Japan, covering a wide variety of needs. For travelers who prefer a fixed amount of data, 118 plans offer a set data cap that can range from 500 MB up to unlimited, while 106 plans give a daily data allowance that can be used on a day‑by‑day basis. Across the board the price range for Japan‑specific coverage varies from about $0.85 to $165.24, and the data cap ranges from a small 500 MB bundle to unlimited data for longer stays.
