Monty eSIM eSIM Data Plans for Japan

Monty eSIM does not provide an unlimited data eSIM for Japan. All plans listed for the destination come with a fixed data allowance, such as a 100GB plan valid for 30 days at $64.50 USD or a 50GB plan also valid for 30 days at $32.99 USD. These are examples of the larger‑sized plans available, though the full catalogue includes a range of options with lower data limits.

Choosing a fixed data plan can be more cost‑effective for most travelers unless they require an extreme amount of data. Monty eSIM’s higher‑capacity plans offer substantial data at a competitive price for users who need significant bandwidth while visiting Japan.

Monty eSIM does not provide a phone number or SMS capability for Japan. The provider offers only data‑only eSIM plans for travelers visiting Japan.

Because a local phone number is not assigned, voice calls and text messages can still be made by using VoIP applications such as WhatsApp, Telegram or iMessage over the available data connection.

Monty eSIM offers 16 single‑country data plans that cover Japan and 35 multi‑country plans that include Japan. The single‑country plans are fixed‑data packages ranging from 1 GB to 30 GB and are priced between about $2.50 and $70. The multi‑country plans provide larger data volumes, up to 100 GB, with prices that can go up to $140. All plans are available for validity periods that span from 7 days to 365 days.
