Ovosim for Japan FAQ

Does Ovosim offer unlimited data eSIM for Japan?

Ovosim does not provide an unlimited‑high‑speed data eSIM for Japan. The plans labeled “Japan Unlimited” actually offer fixed daily data allowances: 10 GB/day for 3 days, 9 GB/day for 5 days, 8 GB/day for 7 days, and 7 GB/day for 10 days. Each of these plans includes a set amount of high‑speed data with no explicit elimination of limits; after the allotted data is used, the speed may be throttled as described in the plan’s features.

If you need a high‑volume data plan instead, Ovosim offers several fixed‑data options for Japan: a 61 GB plan valid for 90 days, and a 51 GB plan valid for 30 days. These plans provide a large amount of high‑speed data within the specified validity period and can be more cost‑effective for most travelers.

Does Ovosim offer Japan eSIM with phone number and SMS?

Ovosim does not provide a phone number or SMS capability for its Japan eSIM plans; only data‑only eSIMs are offered. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may block or restrict certain apps. It is advisable to verify that the specific VoIP services you rely on are accessible in Japan before purchasing an Ovosim eSIM.

How many data plans does Ovosim offer for Japan?

Ovosim offers 31 single‑country plans and 56 multi‑country plans that cover Japan. The available plans span a price range from about $3.35 to $89.60, with data credits between 1 GB and 61 GB and validity periods from 3 to 365 days. Most of the Japan‑specific offerings are fixed‑data plans, though a small number of daily data‑cap options are also available, allowing users to choose a plan that best matches their usage pattern.
