Frequently Asked Questions
Does Spark Roam offer unlimited data eSIM for Japan?
Spark Roam does not offer an unlimited data eSIM plan for Japan. All available plans have fixed data caps.
Instead, Spark Roam provides a range of fixed‑data options, such as a 300 GB plan valid for 30 days at $75.00 USD or a 200 GB plan for 30 days at $60.00 USD. These high‑capacity plans can be more cost‑effective for travelers who use a lot of data, especially given that no unlimited alternative is available.
Does Spark Roam offer Japan eSIM with phone number and SMS?
Spark Roam does not provide eSIM plans with a phone number or SMS capability for Japan. All of Spark Roam’s Japan eSIM offerings are data‑only, so travelers cannot receive or send SMS or make traditional voice calls through a local number. However, popular VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and can be used for calls and messaging without a phone number or SMS functionality.
How many data plans does Spark Roam offer for Japan?
Spark Roam provides 12 single‑country plans and 19 multi‑country plans that cover Japan. The single‑country plans deliver a fixed data amount per validity period, whereas the multi‑country plans often adopt a daily data cap for travelers moving between multiple destinations. Prices vary from roughly $1.33 to $111.00 depending on data size and validity, while data caps range from 1 GB up to 300 GB.
