and from the following options:
•
PIN code request

— to set the device to ask for your PIN or UPIN code every time the device is
switched on. Some SIM cards do not allow the code request to be turned off.
•
PIN2 code request
— to select whether the PIN2 code is required when using a specific device feature which is protected
by the PIN2 code. Some SIM cards do not allow the code request to be turned off.
•
Call barring service
— to restrict incoming calls to and outgoing calls from your device (network service). A barring password
is required.
•
Fixed dialling
— to restrict your outgoing calls to selected phone numbers if this function is supported by your SIM card.
When the fixed dialing is on, GPRS connections are not possible except while sending text messages over a GPRS connection.
In this case, the recipient’s phone number and the message center number must be included in the fixed dialing list.

change the memory in use.
