Roafly eSIM Data Plans for Japan

Roafly does not provide an unlimited data eSIM plan for Japan. All available plans for Japan have a fixed data cap, with the largest options offering 20GB of high‑speed data for a 30‑day validity period.
For travelers who prefer a set amount of data, Roafly offers fixed‑data options such as the Japan 20GB for 30 days plan priced at $22.00 USD and the Japan 10GB for 30 days plan priced at $14.90 USD. These plans give sensible coverage for most users; however, if a traveler is an extremely heavy data consumer, a fixed‑cap plan may be less cost‑effective than a provider that offers an unlimited data option.

Roafly does not offer a Japan eSIM plan that includes a phone number or SMS capability; only data‑only eSIM plans are available. Travelers can still use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

Roafly currently supports 5 single‑country data plans and 10 multi‑country data plans for travelers visiting Japan. The single‑country offerings allocate a fixed amount of data for use solely within Japan, whereas the multi‑country plans provide a data package that can be utilized across several destinations, offering flexibility for extended travel. Across all plans the price ranges from about $3.90 to $89.90, the data caps vary between 1 GB and 20 GB, and validity periods span from 7 to 30 days. The plans also generally allow tethering to share the connection with other devices.
