Call Restrictions - Nokia 3155 User Manual

To ensure the security of your device, you may want to change the preset lock
code to your own selected four digit number. Avoid using codes similar to
emergency numbers to prevent accidental dialling of the emergency number.
If you enter an incorrect lock code five times in a row, your device may ask you for
the security code. By default, the security code is 12345, a five digit number.
With the wrong lock code entered five times in succession, your phone will not
accept your correct lock code for 5 minutes, even if you power off the device
between incorrect entries.
1. In standby mode, select Menu > Settings > Security.
2. Enter the lock code, and select OK.
3. Select Change lock code.
4. Enter the new lock code (must be 4 characters in length).
5. Reenter the new lock code for verification, and select OK.
When changing your lock code, make sure you store it in a safe place, away from
your device. Avoid entering access codes similar to emergency numbers to prevent
accidental emergency calls.

Call restrictions

Select call restrictions to block or allow numbers for incoming and outgoing calls.
With any numbers entered as allowed numbers, all those entered as blocked
numbers are ignored. With a number blocked, the phone blocks any call from it,
and send the caller to the voice mail.
