FAQ
Can I watch YouTube videos every day with a 5GB plan?
At standard quality (480p), a daily viewing pace of 30–40 minutes will last the full month. At 1080p, limit yourself to around 15–20 minutes per day. It is recommended to lock the mobile data quality setting in the YouTube app to 480p to avoid unexpected consumption from auto-quality switching.
Can I use tethering on a 5GB plan?
Tethering is supported on most 5GB plans, but data consumption spikes quickly. Web browsing on a laptop for one hour consumes roughly 500MB to 1GB. On a 5GB plan, tethering should be limited to occasional short sessions — once or twice a week at most.
How much does a 10GB plan cost compared to 5GB?
In 2026, the price difference between 5GB and 10GB plans is typically around 300–700 yen per month. If you consistently have data left over, a 5GB plan with rollover is more economical. If you frequently run short near month-end, upgrading to 10GB is worthwhile.
