Remotely lock your phone!
One of the best additions to the new Symbian is the ability to lock a lost phone by a single SMS! In case you lose your precious phone, this option is a phone-saver! You need to enable this, by going to ”Settings -> Phone -> Phone management”, then to “Security settings“, and then to “Phone and SIM card“. Now, locate the “Remote phone locking” field, and enable it.
You will be prompted to enter the remote locking message (the password). Now you can lock your phone, even if you’re not near the device, by sending an SMS (from any other phone) that contains the remote locking message.
Update phone software regularly.
Nokia will publish various firmware updates for your phone, so make sure you always have the newest version. Because all Symbian^3 phones support OTA (Over the Air) updates, you can easily update software without the PC. Just type in *#0000# (these are zeros), and you’ll see firmware details.
Tap “Options -> Check for updates“, and see if there’s an update from Nokia!
