A good fit if your usage is irregular and you want to access the service as your remaining data allows. Data packs don’t reset monthly or receive a new allowance at the start of a calendar month.
Non-expiring data pack
300GB
¥158/300GB
A good fit for occasional visits to international websites, intermittent research or periods when your work needs are concentrated. Use the data at your own pace without planning around a monthly reset date. This pack includes 300GB total and won’t replenish once used. If you need continuous, long-term access and have steady monthly usage, compare it with a monthly plan rather than looking only at the one-time price.
- 300GB total data
- Use until depleted; never expires
- Unlimited devices

Non-expiring data pack
1000GB
¥358/1000GB
A good fit for users whose activity varies but who want a larger data balance available. Use the data as needed, whether for light browsing or a busy stretch of file work. Non-expiring means the data pack has no expiry date; it does not mean unlimited data or a new 1000GB each month. Make sure you want a lasting total balance rather than a monthly reset allowance.

Best value · Data pack unit price
3000GB
¥658/3000GB
A good fit for users who understand their long-term needs and want a larger total data balance. “Best value” compares the unit price of data packs on this page only; it does not indicate an additional discount or compare data packs with monthly plans. This tier is still a fixed total allowance that lasts until used. If you’re unsure about your needs, compare a smaller pack with a monthly plan instead of choosing more data than you’ll use just for the lower unit price.

Total data vs. monthly data
With a data pack, keep track of your remaining total balance. With a monthly plan, also check when its allowance resets based on your activation date. The data figures on the plan cards aren’t directly comparable: one is a total balance that lasts until used, while the other is a monthly allowance. If you need frequent, continuous access, start by evaluating a monthly plan. If your usage is spread out or includes long gaps, consider whether a data pack better fits your schedule.
For details on switching between billing options or handling an existing plan, check the confirmation information in your user panel first. We don’t promise that data packs and monthly plans will stack automatically, and no transfer, combination or conversion rules beyond those listed are offered. If you have a plan and want to change billing options, open a support ticket with your current plan and target tier, then wait for confirmation before proceeding.
