SIMOVO eSIM Data Plans for Japan

SIMOVO does not provide a truly unlimited data eSIM for Japan; every plan that carries the word “Unlimited” in its name actually limits data to 1 GB or 2 GB per day. These plans stop high‑speed data after the daily limit is reached rather than continuing without restriction.

Travelers wanting higher data volumes can choose from fixed‑data plans instead. For example, SIMOVO offers a 50 GB plan for 30 days at $32.30 USD and a 20 GB plan for 30 days at $18.80 USD, both of which include a generous data allowance and are fully covered across Japan.

SIMOVO does not provide eSIM plans for Japan that include a local phone number or SMS capability. All of SIMOVO’s Japan eSIM offerings are data‑only and do not support inbound or outbound voice or text services.

Travelers who need to communicate can rely on Internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage, which operate over the data connection and eliminate the need for a traditional phone number or SMS service.

SIMOVO provides 31 single‑country plans and 40 multi‑country plans that include Japan. Prices across the catalogue range from $3.00 to $360.90 and data caps vary between 1 GB and 50 GB. The plan selection features 23 fixed‑data‑cap options, which offer a set amount of data for the entire validity period, and 48 daily‑data‑cap options that restrict the amount of data usable each day. Some of the plans allow tethering.
