yaySIM for Japan FAQ
Does yaySIM offer unlimited data eSIM for Japan?
YaySIM does not provide any unlimited‑data eSIM plan for Japan. The only options available for that country are fixed data plans, such as the 50GB plan valid for 30 days at $45.68 USD, the same 50GB plan valid for 180 days also at $45.68 USD, and a 20GB plan valid for 30 days at $34.23 USD. Because these plans have a set data allowance and a fixed validity period, they can be more cost‑effective for travelers who do not need to consume data beyond the specified amount, while heavy data users might consider other payment models.
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.
