Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Japan?
No, Firsty does not offer an unlimited data eSIM plan for Japan. All of its Japan plans have a fixed data allowance of 5GB per day and are priced accordingly.
Firsty’s fixed data plans are available instead, such as the Firsty First Class (Japan) – 1 Day plan that provides 5GB for one day and the Firsty First Class (Japan) – 10 Days plan that provides 5GB per day over ten days. These fixed‑data options can be more cost‑effective for most travelers, though users who need a large volume of data continuously may find a different provider more suitable.
Does Firsty offer Japan eSIM with phone number and SMS?
Firsty does not provide Japan eSIM plans with a phone number or SMS capability. Only data‑only options are offered for travel in Japan. Travelers can still use VoIP applications – such as WhatsApp, Telegram, or iMessage – over the data connection for voice calls and messaging.
How many data plans does Firsty offer for Japan?
Firsty offers 16 data plans that cover Japan alone and does not provide any multi‑country plans. The available plans include two fixed data cap options that offer a set amount of data for the entire validity period, and fourteen daily data cap options that reset the data allowance each day. Prices for these plans range from about $1.74 to $69.62, while the data cap varies between roughly 1.5 GB and 5 GB over validity periods that can be as short as one day or extend up to thirty days.
