Frequently Asked Questions

Does airdatalink offer unlimited data eSIM for Japan?

Airdatalink does not provide an unlimited‑data eSIM for Japan; all plans listed have a fixed data cap, either 30GB or 50GB, for a 30‑day validity period.

For travelers who need a large but not unlimited allowance, airdatalink offers fixed data options. For example, the Japan eSIM (IIJ‑Docomo) with 50GB is priced at $30.37 USD for 30 days, and the 30GB version is $19.22 USD for 30 days. Choosing a fixed data plan can be more cost‑effective unless a user is an extremely heavy data consumer.

Does airdatalink offer Japan eSIM with phone number and SMS?
