Voyasim eSIM Data Plans for Japan

Voyasim does not provide an unlimited data eSIM for Japan. Their offerings are fixed‑data plans, such as a 50GB plan for 30 days priced at $28.90 USD and a 50GB plan for 180 days priced at $42.00 USD. For travelers who need a larger allowance, there is also a 50GB plan with a 180‑day validity for $133.50 USD that covers Japan and 19 other countries. Choosing a fixed‑data plan can be more cost‑effective unless you anticipate consuming data far beyond these limits.

Voyasim does not offer eSIM plans for Japan that include a phone number or SMS capability; only data‑only eSIM plans are available from the provider.

Travelers who need voice or messaging can use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, although some destinations may block or restrict certain apps, so it is advisable to verify that these apps are accessible in Japan before purchasing a plan.

Voyasim offers 43 single‑country data plans for Japan and 58 multi‑country plans that include Japan. These plans cover a price range from about $0.50 to $134.50, with data caps that can be as small as 100 MB or as large as 50 GB and validity periods that stretch from one day to up to 365 days. Some of the plans are fixed‑data packages, while others provide a daily data allowance that reduces each day after activation.
