FAQ
Can I watch video every day and still stay within 20GB?
Watching 2–3 hours per day at standard quality (480p) is well within 20GB. However, watching 2+ hours daily at 1080p may push you over the limit. Setting your video apps to 480p–720p quality on mobile data and consistently using Wi-Fi at home will keep you comfortably within 20GB.
Is a 20GB plan good for remote work?
For hybrid workers (2–3 days at home per week) who work from cafes or while commuting, 20GB is generally adequate. Holding 1–2 video calls per day at 30–60 minutes each and focusing on text-based work otherwise typically stays within 20GB. Full-time remote workers with heavy video conferencing should look at unlimited plans instead.
Should I choose 20GB or unlimited?
If you consistently reach or exceed your 20GB limit each month, switching to an unlimited plan is worthwhile. Unlimited plans are available from around 2,000–3,000 yen per month, and the price gap over a 20GB plan is often only 500–1,500 yen. If you frequently have data left over, the 20GB plan remains the more economical choice.
