Roamify eSIM Data Plans for Japan

Roamify does provide unlimited data eSIM options for Japan. The unlimited plans range from 1 day to 30 days, with prices starting at $3.00 USD for a 1‑day activation and rising to $50.00 USD for a 30‑day package. All unlimited products support 4G, 5G, and LTE network coverage in Japan and include tethering. In most cases, speeds can be throttled after a certain amount of high‑volume data use, a Fair Usage Policy that users should review by contacting Roamify for details on how much data can remain at full speed before throttling applies.

Roamify provides eSIM plans that include a phone number and SMS service while travelling in Japan. The available packages range in price from $15.00 USD to $105.00 USD and offer validity periods from 7 days to 365 days. All plans with telephony feature a mobile number with the dialing code +1 (or +33 for the Japan‑only 20GB plan) and allow both inbound and outbound voice calls as well as inbound and outbound text messages. Users should check with Roamify directly for the exact details of call and messaging rates and to confirm the local number assignment before purchasing.

Roamify offers 45 single‑country plans and 86 multi‑country plans that include coverage in Japan. The available plans range in price from about $2.00 to $140.00 and in data caps from 1 GB to unlimited, with validity periods spanning 1 to 365 days. Tethering is permitted on many of the plans, though speeds may be throttled after the data allowance is reached.
