Call duration management basics: practical steps to reduce overage
If you want to apply this right away, try CallTimer for free.
In call duration management, the key is not only installing an app but fixing your routine. With a call duration timer, using the same rule every time makes results much more stable.
What to check first
- Your plan's free call limit (such as 5 or 10 minutes)
- Billing unit when over limit (example: 22 JPY per 30 seconds)
- Notification style (vibration/alarm)
Basic setup rule
Set the timer about 30 seconds earlier than the plan limit. 4:30 for 5-minute plans, 9:30 for 10-minute plans. Decide a fixed flow to confirm key points and end after the alert.
Review points
Use the setup for one week. If overage remains, shorten by another 15-30 seconds. If margin is too large, move it back slightly. Small adjustments work best.
