MicroEsim eSIM Data Plans for Japan

MicroEsim provides several unlimited‑data eSIM plans for Japan with validity periods ranging from 1 day up to 20 days. Prices for these unlimited plans start at $2.13 USD for a 1‑day plan and can go up to around $57.05 USD for a 19‑day plan, with intermediate options available. The network coverage uses 4G, 5G, and LTE, and normal data speed can be reduced after extensive usage under a Fair Usage Policy, meaning speeds may be throttled once the policy thresholds are exceeded. Travelers who need confirmation about speed limits or the typical amount of normal‑speed data before throttling should contact MicroEsim directly for the most current details.

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.
