Roamify eSIM Data Plans for Japan

Yes, Roamify sells unlimited data eSIM plans for Japan. The plans cover validity periods from 1 day to 30 days and are priced from $3.00 USD for a single‑day plan up to $55.00 USD for a 30‑day plan. All plans support 4G, 5G, and LTE networks.

Roamify labels these plans as unlimited, but they are subject to a Fair Usage Policy, meaning speeds may be throttled after heavy use. Travelers who are concerned about potential speed restrictions should contact Roamify to confirm how long data remains at normal speed under the Fair Usage Policy.

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.
