Regular use? Check your monthly usage
Monthly plans suit regular, everyday use. Before choosing a tier, think about what you’ll use it for: browsing, AI chats, video streaming and file syncing all use different amounts of data. Access to a service doesn’t mean unlimited use, and the number of devices alone shouldn’t determine your plan.
If you don’t have usage history yet, start with your actual needs and track usage trends in the panel. Mid-cycle upgrades prorate the price difference for the remaining days; review the change details shown before proceeding. Data resets based on your activation date, not the start of the calendar month.
Occasional use? Check your remaining data
Data packs cost ¥158/300GB, ¥358/1000GB or ¥658/3000GB. They last until used and never expire. A good fit for project-based work, occasional research or an unpredictable schedule. The key difference is that you use a total allowance instead of receiving new data each month.
“Never expires” describes the validity of the data pack; it doesn’t mean you can keep using data after the allowance runs out. If you already have a monthly plan, don’t assume a data pack will automatically stack, replace it or be used first. Confirm how the products work together through a panel ticket.
