yaySIM for Japan FAQ

Does yaySIM offer unlimited data eSIM for Japan?

No, yaySIM does not provide an unlimited data eSIM for Japan. All of yaySIM’s Japan plans shown have a hard data cap, such as the JP_50_30 and JP_50_180 plans that each offer 50GB for 30 or 180 days. Travelers who need large amounts of data can select one of these fixed‑data plans. Because the data is bundled in a set amount and expires after the validity period, these plans can be more cost‑effective for most users unless they are extremely heavy data consumers.

Does yaySIM offer Japan eSIM with phone number and SMS?

yaySIM does not provide a Japan eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for Japan. Travelers who need to make calls or send messages can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but availability of these services can vary in Japan, so users should confirm that the apps they rely on work locally before purchase.

How many data plans does yaySIM offer for Japan?

yaySIM offers 31 single‑country plans and 69 multi‑country plans that include Japan. The available plans range in price from $2.18 to $132.68 and provide data caps from 102 MB up to 50 GB, giving travelers a broad spectrum of options from low‑cost, low‑data packages to high‑capacity plans suitable for extended stays.
