Viewing call cost
This network feature lets you check the cost of your last
call and all calls. You can also set the maximum cost to
limit the cost of your calls to a certain amount of
charging units or units of currency, and the price per
unit. When the max cost is active, calls can be made
only as long as the preset max cost is not exceeded.
Viewing call cost may not be available, depending on
particular SIM cards. For more information, contact your
service provider.
To view the cost of calls:
On the Dialer screen, tap Tools → Options. You can
also access the screen by tapping the Start menu →
Settings → Personal tab → Phone.
Resetting the cost records to zero
On the Phone (Call Cost) screen, tap Reset Counters.
Setting the maximum cost
On the Phone (Call Cost) screen, tap Set Max Cost.
When the max cost you have set is reached, the counter
stops at its maximum value and you can no longer make
any calls until you reset the counter.
Changing the currency unit per call
On the Phone (Call Cost) screen, tap Set. This price per
unit is applied when calculating the cost of your calls.
