Determining the Call Cost
The Tariff function lets you enter and specify the price per
call unit. The price entered is stored on your SIM card.

and your network.
If you do not specify a price per call unit, the number of
call units is displayed during a call, and in Last Call and
Total Cost in the Call Info menu.

1. Scroll to Call Info , Y E S Options , Y E S , Set Tariff , Y E S .

3. Select Change Tariff .
4. Enter the code for the currency you want, for example
GBP for Pound Sterling, and then press Y E S .

Y E S . To enter the decimal point, press #.

Credit Limit for Calls
If both your network and SIM card support this feature, you
can enter a total amount of money that can be used for mak-
ing calls. This could be useful when you lend your phone to
someone and do not want their call costs to exceed a certain
amount which you can decide. After a call is made, the cost
is deducted from this amount. When the amount reaches
zero, no more calls can be made.
Note! As the price of a call may vary due to where you are
calling from, at what time of the day you are calling and
so on, the credit limit is only an estimated value.
