Driffle eSIM eSIM Data Plans for Japan

Driffle eSIM does not provide a true unlimited data eSIM for Japan. The plans that use “Unlimited” in their names actually contain a fixed high‑speed data allowance of 1GB per day (or 1GB total for the day‑long options). Once that limit is reached the speed would be throttled, although the exact reduced speed is not listed in the available information.

Instead, Driffle eSIM offers several fixed‑data plans. For example, a Japan 20GB plan valid for 30 days costs $21.00, and a Japan 10GB plan for 30 days costs $13.00. These high‑data plans may be more cost‑effective for travelers who need more than the daily 1GB limit.

Driffle eSIM does not provide Japan eSIM plans that include a phone number or SMS capability. The available Japan plans are data‑only, offering high‑speed internet without built‑in voice or text messaging. Travelers can still use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

Driffle eSIM currently offers 12 single-country data plans specifically for Japan, alongside 11 plans that include Japan as part of a broader multi-country coverage area. These plans range in price from approximately $3.00 to $148.00 and offer data allowances between 1GB and 20GB. Within these options, you’ll find both fixed data plans, providing a set amount of data for the plan’s duration, and daily data cap plans which offer a certain amount of data each day.
