SIMOVO eSIM Data Plans for Japan

No, SIMOVO does not provide a truly unlimited data eSIM for Japan. The plans that carry “Unlimited” in their name actually grant a daily data allowance of 1 GB or 2 GB, after which the speed is reduced to 1 Mbps.

Travelers who need more data can choose from SIMOVO’s fixed data plans, such as the 50 GB for 30 days or the 20 GB for 30 days options, which offer larger data allowances without daily limits and can be more cost‑effective for heavy data users.

SIMOVO does not provide any Japan eSIM plans that include a phone number or SMS capability. All available plans are data‑only, so travelers who need a local number for calls or texts must use VoIP or messaging applications such as WhatsApp, Telegram, or iMessage over the data connection. However, they should verify that the specific apps they plan to use are accessible in Japan, as some destinations can block or restrict certain services.

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.
