Select Menu > Settings > Rest. factory sett. (or Reset device or Restore factory sett. or Rest. fact. sett.).
Enter the security code before the restore. If you have never changed your security code, then enter the default code 12345. If your phone still requests a security code or if you have forgotten it, please bring it to the nearest Nokia Care point for inspection.
Security keyguard lets you lock your phone’s keypad with a security code. The security code is asked when you unlock the keypad.
To activate or deactivate the security keyguard:
Note: Note: Once you change your security code, the default setting is no longer valid. If you have changed your security code and do not remember the new code, contact your dealer or local Nokia Care Point.
You can answer a call or make an emergency call while the security keyguard is activated.
Press and hold the key 1 until your device dials to your voice mailbox number or select Menu > Messaging > Voice mail (or Voice messages, or More > Voice messages) > Listen to voice mails (or Listen to voice msgs. or Listen to voice messages). For the first time use, enter your voice mailbox number which you get from your service provider.
Note: The voice mailbox is a network service, contact your service provider for subscription. If supported by the network, the voice mail icon (the icon on the key 1) will display on the device to indicate new voice mails.
To lock the keypad in the standby mode, press the center Navi (scroll) key and then the * key. To unlock, press the same keys.
For QWERTY devices the lock / unlock sequence is Navi key followed by the Fn key (the key showing an arrow in the lower left corner of the keypad).
You can also set the keypad to lock automatically after a time-out, select Menu > Settings > Phone (or Phone settings or Device) > Automatic keyguard > On, enter the time you want and select OK.
Note: When the keypad lock is on, calls may be possible to the official emergency number programmed into your device.
To remove one or more applications from your Series 40 device:
In two (double) SIM phone, only one SIM card can be standby/active at a time.
In dual SIM phone, both SIM cards are available at the same time when the device is not being used (so-called 'dual standby'), but while one SIM card is active, for example, making a call, sending or receiving a message, or transferring data, the other is unavailable.
Select Menu > Settings > Display (or Main display) > Font size.
Both SIM cards can be connected to the network at the same time, but while one SIM card is active, for example, making a call, sending or receiving a message, or transferring data, the other is unavailable.
If your device is a dual SIM device (like X1-01 and C2-00), which means both SIM cards can be connected to the network at the same time, your device has two IMEI numbers.
If your device is a two SIM device (like C1-00), which means only one SIM card can be connected to the network at a time, your device has only one IMEI number.
Only sim 1 IMEI is used to check for warranty.
You can activate call divert to voice mailbox so that the caller can leave messages to your voice mailbox when you are not available.
To activate call divert, select Menu > Settings > Call > Call divert, (for dual SIM devices, select the SIM card to use), and select If not available or If out of reach > Activate > To voice mailbox and enter the voice mailbox number which you get from your service provider.
