Silvy eSIM Data Plans for Japan

Silvy does not provide an unlimited data eSIM plan for Japan.
Instead, Silvy offers fixed‑data plans, such as 20GB for 30 days priced at $22.90 USD and 50GB for 30 days priced at $34.90 USD, both with 5G connectivity and tethering allowed. Choosing a fixed data plan can often be more cost‑effective unless you are an extremely heavy data consumer.

Silvy does not provide an eSIM plan in Japan that includes a local phone number or SMS capability. Travelers who need data only can purchase Silvy’s data‑only plans for Japan.
If calls or messaging are required, popular VoIP applications such as WhatsApp, Telegram, or iMessage can typically be used over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to confirm that the specific applications you rely on work in Japan before purchasing a plan.

Silvy provides seven single‑country plans for Japan and fourteen multi‑country plans that include Japan. The plans vary from $3.90 to $139.90 USD, offering data caps between 1 GB and 50 GB, with validity periods from 7 to 180 days. Single‑country plans are fixed‑data bundles that deliver a set amount of data for the duration of the validity, while multi‑country plans bundle the same data allowance across several destinations, permitting users to remain connected in multiple countries during the same period. Some plans also allow tethering.
