Does airdatalink offer unlimited data eSIM for Japan?
The data available for airdatalink shows no unlimited data eSIMs for Japan. All offered plans have data caps of either 30GB or 50GB and a validity of 30 days. Examples of the larger fixed‑data options include the Japan eSIM (IIJ‑Docomo) 50GB plan priced at $30.43 USD and the Japan eSIM (KDDI) 50GB plan priced at $41.60 USD, both valid for 30 days and using 4G or 5G networks. If you anticipate a very high data usage, a fixed plan might be more cost‑effective compared to a lower‑cap—or not‑available—unlimited offering.
Does airdatalink offer Japan eSIM with phone number and SMS?
airdatalink does not offer Japan eSIM plans that include a phone number or SMS capability. The provider’s Japanese eSIMs are data‑only, so they provide high‑speed internet only. Travelers who need calls or messaging can rely on VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection.
How many data plans does airdatalink offer for Japan?
Airdatalink provides a total of 12 single‑country plans and 6 multi‑country plans that cover Japan. The available plans range in price from about $4.75 up to $41.60 and offer data caps between 3 GB and 50 GB, with validity periods of 15 to 30 days. Some of these plans allow tethering and, where applicable, a reduced speed option at 128 kbps or 200 kbps.
