NOTES ABOUT FIXED DIALING
• If a SIM card with fixed dialing that is activated is inserted into a phone
that does not support fixed dialing, the SIM card is rejected.
• When 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.
• You cannot access SIM memory manually (view or copy numbers on the
SIM card) while fixed dialing is active.
Closed user groups
A closed user group is a network service that specifies the group of people whom
you can call and who can call you. For more information, contact your service
provider.
1 Select Menu > Settings > Security settings > Closed user group > On,
Off, or Default.
2 If you selected On, enter the group number provided by your service
provider, and select OK.
When calls are limited to closed user groups, calls may be possible to
emergency numbers programmed into your phone (for example, 911). Enter the
emergency number and press Call. The number appears in the display after you
have keyed in the last digit.
Security levels
The security level determines your access to features when a non-owner SIM card
is used. A non-owner SIM card is one (other than the original) that is inserted
after you power off the phone. There are three security levels:
Off—Owner and non-owner cards are treated the same.
Memory—The phone will ask for the security code when the SIM card memory
is selected and you want to change the memory in use or copy from one
memory to another.
