nadanada eSIM Data Plans for Japan

Nadanada does not provide an unlimited data eSIM for Japan. All plans listed by the provider limit data usage to a specific amount, such as 10GB, 20GB, 50GB or 100GB for a 30‑day validity period. Travelers who need larger data allowances can choose from these fixed plans; for example, the 100GB 30‑day plan is priced at $109.99 USD and the 50GB 30‑day plan costs $54.99 USD. Selecting a fixed data plan tends to be more economical unless a traveler is an extremely heavy consumer in which case they may need to purchase multiple plans.

Nadanada does not provide an eSIM for Japan that includes a local phone number or the ability to send or receive SMS. The provider offers only data‑only plans for travelers visiting Japan.

Without a phone number, users can still make and receive calls or send messages through popular VoIP applications such as WhatsApp, Telegram, or iMessage that operate over the data connection. However, some destinations may block or restrict specific VoIP services, so travelers should check that the apps they need are accessible in Japan before buying an eSIM from nadanada.

nadanada offers eight single‑country data plans for Japan while there are no multi‑country plans available. The plans vary in price from $2.99 to $89.99 and in data cap from 1 GB up to 100 GB, all of which are fixed‑amount data packages rather than daily data caps, giving travelers a clear overview of the data and cost they can expect.
