SIMOVO eSIM Data Plans for Japan

SIMOVO does not have a true unlimited data eSIM for Japan. All of the plans listed under the “Unlimited” name actually provide a capped amount of high‑speed data, measured as 1 GB or 2 GB per day, and do not offer an unrestricted data allowance. Travelers can instead choose from fixed data packages that give larger total amounts of data. For example, SIMOVO offers a 50GB plan valid for 30 days at $28 USD and a 50GB plan valid for 180 days at $46.10 USD, as well as a 20GB plan for 30 days at $14.30 USD. These fixed‑data options can be more cost‑effective than a plan that limits high‑speed usage after a daily cap.

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.
