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.

2. Press 4 to display the Call Cost menu.
3. Press 3 to display the Maximum Cost screen.
4. Enter the maximum number of call units you want the phone to have
available for chargeable calls.
5. Press YES to enter this information.
If it is an Advice of Charge SIM, you may be required to enter the
"SUPER PIN" on page 27. When the PIN has been confirmed, the
message 'Request Accepted' will be displayed before returning to
standby.
R290 User's Guide
If using a non-Advice of Charge SIM, any attempt to access the Cost
results in the message 'Request Rejected' being displayed.
NOTE:
The call charge indications provided by the phone are only an
approximation of the true cost of your calls as determined by your service
provider. These will be more accurate if you have subscribed to Advice
of Charge, as the phone will calculate call charges using the cost entered
and time units supplied by the Advice of Charge Information (AOCI)
and/or Advice of Charge Charging (AOCC).
