Reviewing Airtime
Your phone records (or logs) and approximation of the
amount of airtime or talk time used. There are two airtime
measurements.
ᮣ
A “Total” measurement that lists the number of calls
made to or from your phone, and the total time in
hours and minutes for these calls. This airtime
measurement can easily be erased by you at any time
and therefore is convenient for estimating your usage
on a daily, weekly, monthly, etc. basis. This feature is
not intended for billing purposes.
ᮣ
A “Lifetime” measurement that shows (in hours and
minutes) the total time spent on all calls (incoming
and outgoing) since your phone was placed into
service. This airtime log is kept for historical and
maintenance reasons and cannot be erased. This
feature is not intended for billing purposes.
The timer rounds each call up to the next minute.
