To set the maximum cost
If you have set a maximum cost, when the total number of call units is
equal to this value, you will be prevented from making outgoing calls and
receiving chargeable incoming calls.
If you are in a call, 30 seconds before this limit is reached, you will be
warned that you have approximately 30 seconds of talk time left by the
RADIO PATH NOT AVAILABLE TONE being given and the message
‘Cost Limit Approaching’ being displayed.
When the maximum cost limit is reached, the message ‘Cost Limit
Reached’ will be displayed and the call terminated. The message ‘Cost
Limit Reached’ or ‘Chargeable Incoming Call’ will then be displayed
on the screen if another call is received.
You will now only be able to make emergency calls and receive non-
chargeable calls (some incoming calls are chargeable) until the cost limit
is reset. This can be performed as long as the SIM supports Advice Of
Charge fields.
