SIM CLOCK STOPPING
*#746025625#

Checks if the sim clock can be stopped. Sim clock stop is a kind of stand-by mode which will save battery time. This code doesn't work with software version 4.59. It will tell you if it can be stopped or not.


EFR CALL QUALITY

NOKIA SPEED TRAP DETECTOR-Urban Legend spread by Nokia Engineers
The settings for radar speed traps detector. Your Nokia cell phone can be programmed to pick up radar speed traps, when programmed your cell phone picks up the radar and alerts you on the message alert tone. ( Doesn't work with Nokia 7110! )
1. Enter your menu
2. Select settings
3. Select security setting`s
4. Select closed user group
5. Select on
6. Enter 00000
7. Press ok
8. Clear back to normal, within a few seconds your phone will display a radar sign with five zero's next to it. It is now activated.

Unfortunately only Nokia phones have this function. The Cell Phone info display needs to be de-activated. Settings -> Phone Settings -> Cell Info display. Each time you turn off your phone, or even each time you loose contact with your carrier, you'll have to activate it again... It is done using steps 1 through 5 above, but the number (00000) will be already on the field as a default.


THE JAMES BOND TRICK
If you short-circuit the left, middle and right pins on the bottom of the phone with all connections touching each other, the Nokia software hangs! The profile "Headset" will be activated. Before you do this just activate the "Automatic Answer" in the headset profile and set the ringing volume to "Mute". Now you can use your phone for checking out what people are talking about in a room. Just place it under a table in a room and call it. The phone receives the call without ringing and you can listen to what people are saying!
