Airdatalink does not provide an unlimited data eSIM plan for Japan. Travelers who need high data allowances can instead choose from fixed‑data plans. For example, aJapan eSIM (KDDI & Softbank) offers 50GB for 30 days at $31.14 USD, and the same provider also offers a 30GB plan for 30 days at $21.41 USD. These paid plans are often more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from an unlimited option.
Airdatalink does not provide an eSIM plan with a phone number or SMS capability for Japan. All of the plans they offer for Japan are data‑only; a phone number, inbound or outbound calls, and SMS are unavailable. Travelers can still use popular VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for voice and text communication.
Airdatalink offers 12 single‑country plans and 12 multi‑country plans for travelers to Japan. These plans cover data from 3 GB up to 50 GB and are priced between $4.86 and $50.60, with validity periods of 15 to 30 days. Some plans include tethering options, while others provide reduced‑speed caps at 128 kbit/s or 200 kbit/s.
