Frequently Asked Questions
Does Flysimo offer unlimited data eSIM for Japan?
Flysimo does not provide an unlimited data eSIM plan for Japan. Travelers can choose from fixed‑data options instead. For instance, the Japan 50GB 30Days plan costs $29.06 USD, while the Japan 20GB 30Days plan is $14.02 USD. These plans include tethering and are valid for the stated number of days.
Selecting a fixed‑data plan can be more cost‑effective for users who consume large amounts of data, as the price scales directly with the amount of data purchased.
Does Flysimo offer Japan eSIM with phone number and SMS?
Flysimo does not offer any Japan eSIM plan that includes a local phone number or SMS capabilities. Their Japan packages are purely data‑only, so travelers cannot make or receive standard phone calls or text messages through the eSIM. For voice and messaging needs, users can rely on internet‑based applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.
How many data plans does Flysimo offer for Japan?
Flysimo lists 14 single‑country plans and 40 multi‑country plans for Japan. The available plans span a price range from about $2.59 up to $153.30 and provide data caps between 1 GB and 50 GB, with validity periods ആര് 7 to 365 days. Some plans also permit tethering.
