Airhub eSIM Data Plans for Japan

Airhub does not provide a truly unlimited data eSIM for Japan.
The plan titled “China Korea Japan unlimited data” actually grants 10GB of high‑speed data for 1 day and, after that cap, reduces the speed to 2000kbps. That is a capped plan and not an unlimited one.

Airhub offers several fixed‑data plans for Japan, including 100GB for 30 days, 750GB for 10 days, and 50GB for 30 days. These fixed‑data options give large data allowances and can be more cost‑effective for travelers who need substantial high‑speed data without the speed cut‑off that comes after the capped limit.

Airhub offers Japan eSIM plans that provide a local phone number with the dialing code +81 and support for both inbound and outbound voice calls. The plans available include 20GB, 50GB, and 100GB data allowances, each valid for 30 days, with prices ranging from $32.00 to $69.00 USD.

The dataset does not indicate SMS capabilities for these Japan plans, so it is unclear whether SMS can be sent or received. Travelers who require SMS functionality should confirm directly with Airhub to ensure the plan meets their needs.

Airhub provides a total of 29 distinct data plans for users visiting Japan. 13 of these plans cover only Japan, while an additional 16 plans allow roaming across multiple countries for travelers who wish to stay connected beyond Japan. The available packages span a price range from US$2.50 to US$69, with data caps varying from 1 GB up to 750 GB and validity periods that can be as short as one day or as long as ninety days. Many of the plans permit tethering and include a speed limit of 5000 kbps, with reduced speeds capped at 2000 kbps when necessary.
