Roamify eSIM Data Plans for Japan

Roamify provides unlimited data eSIM plans that cover Japan. The plans start at 1 day for $3.00 USD and extend up to 30 days for $50.00 USD. They are available on 4G, 5G, and LTE networks, and the description indicates that speeds may be throttled after heavy usage.

Un­limited plans are subject to a Fair Usage Policy, so normal speed can be reduced if many gigabytes are used in a short period. Travelers who want to confirm the exact amount of data that remains at full speed or who want to discuss the Fair Usage Policy should contact Roamify directly.

Yes, Roamify offers several eSIM plans for Japan that include a phone number and SMS capability. The available plans range from 1GB data for 7 days at $15.00 USD to 20GB data for 365 days at $105.00 USD. Each plan provides inbound and outbound voice calls as well as inbound and outbound SMS, and the assigned phone number carries the dialing code +1. This means the number is not a local Japanese number, but it lets users send, receive, and dial (in or out) from Japan. For precise details about call rates, SMS charges, or to confirm any specific needs, users should contact Roamify directly.
