Monty eSIM eSIM Data Plans for Japan

Monty eSIM does not provide an unlimited data eSIM for travelers in Japan. All of its plans for the country have fixed data caps.
Instead, Monty eSIM offers large‑data fixed plans that may be more economical for most users. For example, a 100GB plan valid for 30 days costs $64.50 USD, and a 50GB plan for the same period is priced at $32.99 USD. These capped plans allow for substantial data usage while remaining predictable in cost, making them a practical choice unless a traveler needs unlimited data for very heavy consumption.

Monty eSIM does not provide Japan eSIM plans that include a phone number or SMS capability. Only data‑only eSIM plans are offered for Japan, and travelers can use VoIP applications such as WhatsApp, Telegram and iMessage to make calls and send messages over the data connection.

Monty eSIM lists 16 single‑country data plans that cover Japan alone and 17 multi‑country plans that include Japan among other destinations, offering customers 33 distinct options. The plans come in two main types: a fixed data amount (for example 5 GB for 30 days) and a daily data cap (for example 200 MB per day for 10 days), allowing travelers to choose based on usage patterns. Prices span from around $2.50 for the shortest, lowest‑capacity offerings up to about $134.50 for the longest, highest‑capacity selections, and data caps range from 1 GB to 100 GB.
