Does Flysimo offer unlimited data eSIM for Japan?
No, Flysimo does not offer unlimited data eSIM plans for Japan. Instead, Flysimo provides fixed data plans such as the Japan 50GB 30Days (IIJ) and the Japan 50GB 180Days, both of which include the option for tethering and are valid throughout Japan. Choosing a fixed data plan can be more cost effective for most travelers, unless an extremely heavy data consumer requires an unlimited option.
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 provides 14 single‑country data plans that cover only Japan and 40 multi‑country plans that include Japan among other destinations. The plans are priced from roughly $2.56 to $130.92 and offer data amounts between 1 GB and 50 GB, with validity periods ranging from 7 to 365 days. Several of the plans also allow tethering.
